Project Files and Concurrent Design

Autodesk Inventor is very flexible in its ability to handle the needs of the small shop with individual users

designing entire products, to large customers with 20 person teams working in a concurrent design

environment.

No one likes to read a Users Manual. You certainly dont want to have to read one before you test drive

a new car and you shouldnt have to. Nevertheless, if you want to optimize the longevity of that new

vehicle and minimize your maintenance costs, it might be a good thing to get acquainted before you log

too many miles. Project Files and file management in Autodesk Inventor is a little like that. You dont

need to know about it to use Autodesk Inventor for the first time, but users often remark after getting

some education on this subject, That should have been the first thing you taught me!

Projects

What are projects?

Autodesk Inventor uses projects as a means of identifying and structuring the valid locations where filescomposing a product design are stored. When Autodesk Inventor searches for a file, it looks in the

locations defined by the Active Project. Project files are very flexible and can address the simple needs

of a single user working on a small assembly, and large multi-user teams working on assemblies

composed of thousands of parts.

When Autodesk Inventor is first installed, it contains three projects. The first is the Default project,

which allows a user to create simple assemblies of parts with no setup required. The second project is

Samples, and allows easy access to all the sample files delivered with Autodesk Inventor. Lastly, the

Tutorials project is used to teach the basic design workflows of Autodesk Inventor.

How do projects benefit the user?

Projects allow products designed in Autodesk Inventor to be largely independent of the file system. Thisindependence makes the set of files defining a project more portable, easier to archive, and easier to

restructure their layout within the network as the design grows. Often when a design starts, it is easily

contained in a single directory, but as it grows and more designers become involved, it may spread out

across multiple directories, disks, and servers.

Another benefit of Projects is that it provides a common framework for a design team. Each member of

the design team references a common project thereby providing a shared view of the design from a file

management perspective, and ensuring that key Autodesk Inventor setting are common for all users

working on the design.

How do projects work?

The Active Project defines how Autodesk Inventor searches for a file that is referenced by another file.How this is done is critically important to the smooth functioning of Autodesk Inventor since a product

design is composed of a large number of files that contain references to one another.

In Autodesk Inventor, each part and assembly

is contained in a separate file. A subassembly

is defined by storing references to the parts and

subassemblies that it contains. New parts can

be derived from other parts using file

references. Lastly, drawings reference the file

that they are documenting. So, if a product

design is composed of 1,000 parts, 100

subassemblies, and 1,100 drawings, there are atleast 2,200 Autodesk Inventor files that

reference one another.

File References

The files composing a product design can be stored virtually anywhere on the network. So how does

Autodesk Inventor know where to find a file referenced by another file?


4/49


www.autodesk.com 4

Historically, this has been done by the parent file storing an absolute path to each file it referenced.

This is a very inflexible system. If a file is moved, files that reference it do not find it and the user has to

intervene. Even then, the part file has to be edited to store the new location. This can be a problem if the

file represented a released file or a file that is read-only.

Autodesk Inventor takes a different approach where a minimum set of information is stored, most notably

the name of the file. To find the file, Autodesk Inventor searches in the file storage locations defined by

the active project. Using this approach, a file can often be moved to a different location within the project

and Autodesk Inventor still finds it without user intervention.

How does Autodesk Inventor search for files?

When Autodesk Inventor needs to find a file, it searches for it using the Active Project. The project

defines options that control Autodesk Inventor file management functionality and may contain storage

locations defining where Autodesk Inventor should search for files. With the exception of Libraries,

Autodesk Inventor searches storage locations in the order they are defined within the project file. A

project file can define two fundamentally different types of storage locations: Editable Project Locations

and Libraries. The editable project locations are further subdivided into three categories: Workspace,Local Search Paths, and Workgroup Search Paths. When the different types of storage locations should

be used is discussed later in this document.

This is a sample of a complex project file using

features not required by many users, but illustrates

how Autodesk Inventor searches for referenced files.

A file reference stored within an Autodesk Inventor file can be in one of two forms: Library and non-

Library.

Library reference

Most assemblies contain a significant number of what Autodesk Inventor refers to as Library parts.

Library parts are read-only parts that cannot be edited. Often parts contained in libraries are shared by

multiple projects; that is to say, they are used in the design of multiple products. Most commonly,

libraries contain standard hardware such as fasteners or purchased parts such as motors or hydraulic

cylinders. In the case of very large assemblies worked on by multiple design groups (structural,electrical, hydraulics), a library may contain the baseline work of another design group.

Autodesk Inventor makes use of the properties of library documents to enhance performance. When an

Autodesk Inventor file references a library document, it stores:

Library Name

Filename


5/49


www.autodesk.com 5

Subfolder Path (may be empty)

Non-Library reference

Storage locations that are not defined as libraries contain files that the user edits during the design

process. It is often the case that as the design matures; the files are moved either to different storage

locations, or to subfolders of the current location.

When an Autodesk Inventor file references a document not contained in a library, it stores:

Filename

Subfolder Path (may be empty)

What is a subfolder path

A project file defines storage locations where Autodesk Inventor looks for a file when it is referenced

from another file. Without any supporting information, Autodesk Inventor only looks in the folder

defined by the storage location; it does not look in any of the subfolders. Sometimes it is convenient to

create a structure of subfolders within a storage location to classify design files in various ways.

When this is done, how does Autodesk Inventor know to look in the subfolder?

When a part is placed into an

assembly, Autodesk Inventor

performs a process called back

resolution. At the time the part is

placed into the assembly,

Autodesk Inventor knows exactly

where it is located even though

this absolute path is not stored in

the assembly. Using back

resolution, Autodesk Inventorfinds the corresponding storage

location, and determines the

subfolder location relative to the

storage location.

Active Project

Subfolder

6/49


www.autodesk.com 6

As an example, lets say that the user places the part DIN1587.ipt into an assembly using the Project File

information shown in the previous figure.

Autodesk Inventor knows that the absolute

location is:

\\server\library1\nuts\hex\din1587.ipt

Autodesk Inventor back-resolves this

location and finds that the location

corresponds to Library1 which has a storage

location of:

\\server\library1\

It then determines that it is located in a

subfolder path of:

nuts\hex\

referred to as the subfolder path

The file resolution information stored in the assembly is then:

Library Name Library1

Subfolder Location -- nuts\hex\

Why doesnt Autodesk Inventor just search the storage location and all its subfolders, and not store a

subfolder location? Performance!

Autodesk Inventor was designed to handle assemblies of thousands of parts. If Autodesk Inventor had to

search each storage location for each part, File Open performance could be impacted. By storing a

subfolder location, Autodesk Inventor knows exactly where to look.

The Autodesk Inventor File Open and Save dialogs present the subfolder path graphically within the

Locations explorer pane.

In this example, the project file has three

library locations, one of which is calledFasteners. The Fastener library is selected.

The blue folder indicates that Autodesk

Inventor recognizes the Fastener library as

the storage location.


7/49


www.autodesk.com 7

In this example, the project file has five

library locations. The Bolts and Nuts

locations are subfolders of the Fastener

library.

Notice that the Fastener library has a blue

folder even though Nuts is selected

When Autodesk Inventor back-resolves the

location, it matches the location of the

Fastener library and quits looking before it

encounters Nuts, which is a subfolder of

Fasteners. From Autodesk Inventors

viewpoint, any part placed from the Nuts

Library is really placed from the Fastener

library with a subfolder path of Nuts\.

The only real value of the Nuts library in

this case is as a convenience to the user innavigating to that section of the Fastener

library.

The search process

Perhaps the most important part of the search process is what Autodesk Inventor does if it does not find

the file in any of the libraries or search paths. This is the situation when the Default project is used. In

this situation, Autodesk Inventor looks in the location containing the parent file. If Autodesk Inventor still

does not find the file, it then asks the user where it is located.

It may seem odd that Autodesk Inventor tries to look where the parent file is located if it is not found in

the library. This is done to enhance portability of Autodesk Inventor data sets. By always looking in the

location containing the parent file, it is always possible to gather up all the files defining a design and putthem in a single location. When this is done, Autodesk Inventor is able to find all the files. This ability

allows an Autodesk Inventor data set to be easily mailed to a subcontractor or archived for historical

value or legal requirements. It is important to note that duplicate file names must be avoided, or a

document will be overwritten. In general, it is a good rule to avoid having different documents with the

same file name.

A Library Reference

When Autodesk Inventor searches for

a document, it first looks at the

information describing the reference to

see if it is a library document. This is

achieved by looking to see if a Library

Name is present. If a Library Name is

present, Autodesk Inventor looks up

the name in the Active Project to find

the corresponding storage location.

File

Libraries

Active Project

Subfolder

Location

The Autodesk Inventor search for the file takes the following steps:

1. Autodesk Inventor first looks using the subfolder location in: \\server\Library1\nuts\hex\.

2. If the file is not found, Autodesk Inventor looks in: \\server\Library1\.

3. If the file is not found, Autodesk Inventor looks in the location containing the parent file.

A Non-Library Reference

When Autodesk Inventor searches

for a file, it first looks at the

information describing the

reference to get the file name, and

if present the subfolder location.Based on the active project,

Autodesk Inventor searches the

storage locations defined in the

order they are listed.

Local1 = \\server2\project1\local1\Local2 = \\server2\project1\local2\

then the basestorage location

Subfolder

Location

Autodesk Inventor searches for the file in each storage location in the order they are listed. The search of

a storage location is a two-step process:

1. If a subfolder path is defined, Autodesk Inventor first searches relative to the storage location

using this path. Using the storage location Local1 as an example, if the subfolder path was

aaa\bbb\, then Autodesk Inventor first searches in \\server2\project1\local1\aaa\bbb\.


9/49


www.autodesk.com 9

2. If not found, then Autodesk Inventor searches in \\server2\project1\local1\.

3. If the file is not found in any of the storage locations defined in the active project, then Autodesk

Inventor looks in the location containing the parent file.

File not found

When Autodesk Inventor cannot find a file using the active project, it presents the Resolve Link dialog

box. The resolve link dialog allows the user to specify the current location of the file being referenced

within the Active Project. Once Autodesk Inventor can find the file, it writes new information into the

file containing the reference the next time it is saved. As a result, the file will be found the next time the

referencing file is opened.

There are several situations when Autodesk Inventor cannot find a file:

The file no longer exists within any of the storage locations defined by the active project.

The file has been moved from one library to another.

The file has been moved from one subfolder to another within a storage location or library.

There are network or server problems.

The dataset was taken home without the shared libraries. This may be acceptable, but the

dialog is displayed and the Skip All option chosen.

The Resolve Link dialog box provides information useful in diagnosing why Autodesk Inventor cant find

the file.

Filename The name of the file that is being referenced. Maybe the file was simply renamed.

Relative path This is the subdirectory that Autodesk Inventor is looking in relative to each

storage location defined in the Active Project.

Library name If the file was placed from a library, this field contains that librarys name.Maybe the project file was edited and the library was removed, or its name was changed.


10/49


www.autodesk.com 10

Depending on the reasons that Autodesk Inventor cant find the file, you can take different corrective

actions.

Move the file to a location covered by the active project. If you move the file to a subfolder of a

storage location, you still must tell Autodesk Inventor where the file is using the Resolution

Dialog (one time) to establish the correct subfolder path.

If the file exists within a location covered by the active project, you tell Autodesk Inventor where

it is using the Resolve Link dialog box.

It is often the case that the reason Autodesk Inventor cant find one file is the same reason it cant find an

entire set of files. For example, if the name of a library was changed, none of the files placed from that

library will be found.

Obviously, it would be a tedious process to have to specify the location of each file that could not be

found when they all cant be found for the same reason. To address this problem, Autodesk Inventor

provides what is called a substitution rule. When you browse to a new location, Autodesk Inventor

automatically creates a simple substitution rule that allows it to find other files that could not be found for

exactly the same reason.

Using the More button (>>) on the Resolve Link dialog box, you can see the substitution rule that

Autodesk Inventor automatically creates. Depending on the situation, you may be able to edit the

substitution rule (usually by deleting some tail portion of the paths) to further reduce the number of times

Autodesk Inventor asks where to find a file. Take the following example where the user desires to change

the name of folder ABC to DEF.

asking for the location of 1.ipt. After browsing to 1.ipt, the dialog would be filled in as follows:


12/49


www.autodesk.com 12

The automatically generated substitution rule represents the change in subfolder path. If the Open button

were selected, the dialog would appear for part 2.ipt and for each of the other parts. However, what is

different for each parts subfolder path is that ABC changed to DEF. If you edit the path as follows, all

the parts will be found.

Defining a project

Autodesk Inventor provides a Project Editor that can be used to edit existing projects and create newprojects. The Project Editor is available both outside Autodesk Inventor and from within Autodesk

Inventor. Activate the Project Editor from within Autodesk Inventor by selectingFile>Projectsfrom the

menu. Outside Autodesk Inventor, use the Microsoft Windows Start menu to selectPrograms>Autodesk

Inventor >Tools>Project Editor. When using the Project Editor, it is important to note that

the active project cannot be edited while files are open in Autodesk Inventor. If you need to edit the

active project or change which project is active, close all open Autodesk Inventor files.

A project defines where Autodesk Inventor looks to find your files when other files reference them. You

can create as many projects as you need to suit your working environment. Some users find the default

project that comes with Autodesk Inventor is suitable for all their needs. Others users may decide to

create a project for each design that they work on.

New project

The New button invokes a project creation wizard. It is important to note than many of the defaulted

values of the wizard are based on the project file that is selected in the project editor when the command

is invoked.

Step 1

The first page of the wizard asks what type of project is to be created: Personal Workspace or New

Project.

If you are not using Autodesk Inventors Multi-User functionality (covered later in this document) to

implement a semi-isolated workflow, then you always want to choose New Project. If you are working

within a Multi-User environment using a semi-isolated workflow, which option you choose is based on

the following question:

Are you adding a user to an existing design project, or creating a new design project for people to share?

If you are adding a user to an existing Semi-Isolated design project, select the Personal Workspace

option; otherwise, select the New Project option.


13/49


www.autodesk.com 13

Step 2

The next step (for both types) is to provide the basic required information.

Name

This is the name that is shown in the Project List when choosing which project to make

active.


14/49


www.autodesk.com 14

Location

This is the location where the Project File (.ipj file) is stored. The Project File defines all

aspects of the project including Search Paths and Libraries. It is good practice to co-locate

the project file with the files it is to manage with the possible exclusion of the libraries.

Note: Ideally, project search locations should be in subfolders of the folder containing the

Project File. If you decide to create a new project file for an existing design folder, it

would be best to move all of the files to a workgroup subfolder that the Project Editor (by

default) creates for you.

Workgroup Search PathsLibraries

Library 1

Workgroup 3

Library 2

Location of New or Existing Files

This is typically the location of Workgroup1 as denoted in the preceding figure. While there

may be several search paths, most situations only call for a single search path so the option to

specify it up front is provided. You can leave this field blank and define your search paths at

a later step in the process.

Step 3

The final step is to specify any libraries. While you may specify libraries after completing the wizard, it is

often the case that a new project uses the same libraries as existing projects. The wizard makes it easy to

reuse these library definitions. The libraries in the left pane are a combined collection from all the project

files you have identified in the project editor. Those in the right pane are identical to the libraries in the

project that was selected when you initiated the wizard through the New command.


15/49


www.autodesk.com 15

Edit project

There are many situations when you would want to edit a project. You may need to add new search path

locations, edit the location of existing paths, or edit a newly created project. Most Project Editor

functions are available from the context menu.

The order of search paths in the Project File impacts

how Autodesk Inventor searches for files.

Conceptually, it searches in the order they are listed.

To change the order of the search paths, select a search

path and use the Up and Down buttons on the toolbar.

Options

The Project File allows the specification of options that should be adhered to by all users of the project.

Multi User Sets the Autodesk Inventors mode

of operation. There are three settings: Off,Shared, and Semi-isolated

Old Versions Each time a file is saved, the

previous version of the file is stored in a

subfolder called OldVersions. This option

controls the number of old versions that are

kept.

General construction guidelines

Consider the following tips and guidelines for creating projects.

If you have a small assembly where there is only one designer, consider keeping all the AutodeskInventor files in a single directory and using the Default project.

Create libraries for read-only parts such as fasteners or purchased parts. Using libraries can

increase performance of large assemblies.

If your assemblies are less than 200 parts, create a search path for each directory where files will

be stored. This allows for more flexible restructuring as file references does not include any

subfolder path information.

Note: When creating search paths that are subfolders of other search paths it is critically

important that the subfolders be listed first in the project file.

If a Workspace is defined, never define storage locations that point to subfolders of theWorkspace. For example:

This is OK

Workspace = c:\my design\workspace

Workgroup1 = c:\my design\abc

This is NOT ok

Workspace = c:\my design\workspace

Workgroup1 = c:\my design\workspace\abs

Assign a meaningful unique name to each Search Path and Library. Meaningful names maximize

the usability of the File Open and Save dialog boxes.

To maximize portability of your Autodesk Inventor data sets, define all storage locations as

subfolders of a directory, which only contains the project definition file (.ipj file). Set the Project

Files Use Relative Paths option to True.

The Projects folder

The Projects dialog box displays a list of all Autodesk Inventor projects you have created through New or

browsed to using Browse. Given that each file defining a project is usually stored with the data set it

controls, how does Autodesk Inventor know how to construct the list of Projects?


17/49


www.autodesk.com 17

Autodesk Inventor constructs the list by looking for shortcuts to the project files, which are stored in the

Projects Folder as defined in the Files tab of the Autodesk Inventor Options dialog box.


18/49


www.autodesk.com 18

The File Open and Save Dialog boxes

The Autodesk Inventor Save and Open

dialog boxes make it easy for the user to

select files located within the active project.

The Locations explorer of the dialog box

lists the Workspace, Search Path, and

Library locations defined by the Active

Project.

The Default project

Autodesk Inventor is installed with a Default project. The Default project is all that many users require to

effectively use Autodesk Inventor. This is especially true in a single user environment, or multi-user

environment where design data is segregated and there is no fear of users editing each others files.

Following are some scenarios where the Default project may provide sufficient file management

flexibility.

Case study 1

There are multiple design projects, but each design is a self-contained set of files that can be co-located in

a single folder. There is no sharing of data between the designs through file references. When there is aneed to share data, the design files are copied.

In this situation, the Default project delivered with Autodesk Inventor is sufficient. There is no need to

define any search paths or libraries. When Autodesk Inventor needs to find a referenced file, it can

always find it co-located with the referencing file, or in a subfolder of where the referencing file is

located.

Case study 2

There are multiple design projects where each project is a self-contained set of files with the exception of

standard hardware, purchased items, or previously released data, which will not be edited.

This is a case were Libraries can be employed to define the locations where the shared content will be

stored. Why not use Search Paths? Libraries are better suited for several reasons:

Autodesk Inventor treats library data as read-only. This prevents accidental editing of shared data

files.

While unlikely, it is conceivable that files in different libraries may have the same file name even

though they represent a different part. For example, suppliers of motors and air cylinders both

deliver a part with the same filename. There is no global naming authority to ensure this does not


19/49


www.autodesk.com 19

happen. Autodesk Inventor treats Libraries as Name Spaces, which means that Autodesk

Inventor understands and allows each library to have a part with the same name.

Libraries can increase performance of assemblies of significant size.

There are two good ways to approach this problem. The first is to edit the Default project supplied withAutodesk Inventor by adding Libraries to it. (You may need to change the file property from Read-Only,

first.) Autodesk Inventor only allows libraries to be added to the Default project; no workgroups or local

search paths can be added. The second approach is to create a new project and add the required libraries.

There is essentially no difference between the two approaches.

File versions

Each time Autodesk Inventor saves a file, it creates a new file and moves the existing file into a folder

called OldVersions. Each location where Autodesk Inventor files are stored will have an OldVersions

directory if any of the files have been edited and saved.

The previous versions of an Autodesk Inventor file

have a very specific naming convention.

..

Autodesk Inventor creates versions for two reasons. First, it is an essential component to the functioning

of Autodesk Inventors Multi-User environment. Second, it provides the ability for a user to retrieve aprevious copy of a file. It is very important to note that Autodesk Inventor provides versions on a per file

basis. As a result, a user can restore an old version of an assembly file, but there is no automated way to

restore thestateof an assembly including the edits to all the various parts.

When it is required to restore an old version, there may be a temptation to move the file and rename it

using the MicrosoftWindows Explorer. Doing so can have a variety of undesirable side effects.

Restoring an old version should be accomplished by asking Autodesk Inventor to restore the file. Using

the File Open command, select the file you want to restore from the OldVersions directory. Autodesk

Inventor then displays the following dialog box.


20/49


www.autodesk.com 20

Autodesk Inventor provides three options for proceeding:

Open that old version of the file. Since the current file still exists, you cannot save, but you can save

a copy.

Make the selected old version the current version. It is important to note that the current version is

not lost, as it now becomes a file in the OldVersions folder.

There are times when it may be an accident that an old version was opened. The open current

version option opens the current version of the file.

Autodesk Inventors Multi-User environment

Autodesk Inventor does not provide a PDM system, but it does provide tools that enable design teams to

work productively in a multi-user environment. The Autodesk Inventor file management facility provides

the following important capabilities:

Concurrent design Allows users to work in the context of the same assembly, while avoiding

conflicts when editing.

Collision avoidance In a multi-user design environment where only one user can edit a document at

a time, it is essential that users do not overwrite each others edit, but at the same time can work in the

context of the same assembly.

Personal Workspace A user can spend days working on a change, only to decide to take a different

design approach, or even decide the design was perfect the way it was. In such an environment, a

designer only wants others to see changes they decide are ready for the design team to see.

Refreshing the users design session to see changes made by others.


21/49


www.autodesk.com 21

Autodesk Inventor provides a solution of these

needs through its Multi-User environment

which can operate in two different modes,

Shared and Semi-Isolated.

The Multi-User option is defined by the Active

Project and can be edited through the Project

Editor.

The two modes of operation offer different advantages. Shared mode provides for collision avoidance,

but does not isolate each user from the in-work changes of others. Some customers find that this is not a

serious limitation in their environment and that the Shared mode of operation is easier to administrate.

When to use Shared mode

The multi-user Shared mode is mostly provided for legacy support. Prior to Autodesk Inventor release 6,

it was very difficult for customers to setup and manage a Semi-isolated, multi-user environment. As a

result, customers tended to use multi-user in Shared mode

Customers that have been using a Shared mode of operation prior to Autodesk Inventor release 6 may

want to continue to use Shared mode as a stepping stone to a Semi-isolated mode of operation.

Semi-isolated mode

Semi-isolated mode is similar to Shared mode, except that parts to be edited are copied to the users local

workstation. Files not copied continue to be referenced from the central server. In this example, Gary,

Christian, and Paul have all opened the top-level assembly A. Gary has the four green components

which he is editing copied to his workstation, but references the remainder of the files from the server.

Christian and Paul will not see

the edits that Gary makes until

they are copied back to the

server.

A common Project file defines

Workgroup Search Paths and

Libraries.

Each user has a personal project

that includes the group project

file, but also defines a personal

workspace.

Setting up for Semi-Isolated mode

When working in Semi-Isolated mode, it is most common for each user to have a project file that defines

only a workspace and that includes a group project file located on the server.

When the user performs a file Check

Out operation, a copy of the file will

be placed in the users personal

workspace.

Other users will not see changes to

this file because the group project file

knows nothing about this location.

Each users workspace keeps a

private copy of the files they are

editing.

Autodesk Inventor Check-in/Check-out

Both the Shared and Semi-Isolated modes provide a Check-in/Check-out facility. The functioning of the

facility is somewhat different in the two modes, but the function is the same. It allows users to reserve

files for editing.

When Autodesk Inventor is in a Multi-User mode

of operation, a File Status browser is provided.

The File Status browser allows users to perform file

management operations such as check-in and

Check Out, as well as communicating the status ofall open documents.

To the left of each project based item in the browser is a status box. (The status box is missing if the file

is in a library or outside the project altogether.) The status box can have the following values:

You checked out the file, but have not saved edits. It is possible that edits were made that

have yet to be saved.

You checked out the file and saved the changes.

There is some discrepancy between the Check Out state of the file in the workgroup and the

workspace. The most common reason is that a new file was created and saved to the

workspace. Since the file was never checked in, it is unknown to other users. You can use

the Resolve command to define the status of the file.

The file, as you see it, is out of date relative to the most current version available. This results

from someone else updating a file in the workgroup (Check-In in Semi-Isolated mode or Save

in Shared mode) that you currently have open. To see the latest version, you must reopen the

assembly or use the Refresh command.

The file is checked-out by someone else and is unavailable for edit.


26/49


www.autodesk.com 26

You canceled the Check Out of a file that you edited and saved to your workspace. However,

what you currently see is the edited file (now in the OldVersions folder in the workspace) and

not the original on the server. To see the current version on the server, you must reopen the

assembly or use the Refresh command.

The File Status Browser has a toolbar that

controls the presentation of content.

The first three buttons define the current filter,

of which only one can be selected at a time.

The last button is the Refresh All command.

The browser does not track in real time the

moment-to-moment changes that are taking

place as users check in and check out

components. The Refresh All command

synchronizes the status presented in thebrowser with the actual status of the files you

have open. If the file you have open is in the

workspace, the full status relative to the

workgroup file is only updated when you

Check-in/out, Cancel Check Out, or Resolve

Check Out.

The Check Out process

Lets first take an example of a semi-isolated workflow where no files are checked out. The context menu

for each item contains a Check Out entry, and if the selected item is an assembly, there is a Check OutTree entry.

The Check Out command marks just the selected item as reserved

and copies it from the appropriate Workgroup Search Path to the

Workspace. The Check Out Tree does the same for the assembly

and all dependents.

27/49


www.autodesk.com 27

After the assembly is checked out, each item in the File Status

browser has a check mark next to it.

The black check mark indicates that you have the file checked

out, but that no edits have been saved.

After checking out the files, the Large Cap and Shaft parts were

edited (but not saved). The File Status browser indicates files that

have edits that are not saved to disk by appending an asterisk

symbol (*) to the end of the name.

Notice that the Tuner also shows as having edits even though you

did not explicitly edit Turner. Many actions that you can take

will make changes to a file that you do not expect. The good

news is that the Save command does not require you to save

Turner, it gives you the option.

When the Save command is invoked the Autodesk Inventor Save dialog box is presented. The dialog box

lists each file that was edited either explicitly by the user or indirectly by Autodesk Inventor. For each

file in the list a Checked Out status is displayed along with a Save option. By default, Autodesk Inventor

assumes that you want to save all files that are checked out and were edited. If you dont want to edit one

of the files, click Yes and it changes to No. If a file is not checked out but available, you can click on No

and it changes to Check Out/Yes.


28/49


www.autodesk.com 28

When you save the files, the File Status browser reflects a status

of . This status indicates that the files have been edited and

saved by changing the status mark from a black check mark to a

green filled check mark.

Note: Sometimes the status may not automatically update. To

verify the status of files, use the File Status browsers Refresh

command.

Creating new files

A common practice is to add new files. The user might accomplish this by several methods. In all cases,

the dialog boxes allow the user to specify both the name of the new file and where to save it (for example,

what Project location and subfolder path).

Using the Assembly Create In Place dialog box.

Using the File New command.

Using the Save Copy As command


29/49


www.autodesk.com 29

This example shows two

new parts created using

the Assembly Create In

Place command. This

command allows theuser to specify where to

save the file.

The first part was saved to a Workgroup Search Path and the

second to the Workspace.

The next step is to use the Save command. Notice that one

part has a status of , and the other a .

The means that there is a discrepancy in the Check Out

status between the file in the workspace and the

corresponding file in the workgroup. The most common

reason is that a new file was created and saved to the

workspace. Since the file has never been checked in, it has

no corresponding file in any of the workgroups and Autodesk

Inventor does not know in which workgroup the user

ultimately plans to store it.

It is best to resolve such situations as soon as possible to

ensure that another user does not create a file with the same

name.


30/49


www.autodesk.com 30

The File Status browsers Resolve command can be used to

investigate the details of and set the Check Out status of the

file.

When the Resolve command is used on a file of unknown status, the following dialog box is presented.

The Resolve Check Out dialog box allows the user to specify which Workgroup is used to store the new

file by selecting one of the Projects Workgroups from the drop-down list. After choosing the desired

Workgroup, you can use the Create Check Out command to reserve a location on the server for the new

part and ensure that another user does not take the filename.


31/49


www.autodesk.com 31

After using the Resolve Check Out command, the file initially

saved to the Workspace now has a status of , meaning that the

file is checked out and that the file in the Workgroup is at a

different current version than the one in the Workspace.

In the case of workspace file that has never been checked in, the

file in the workgroup is conceptually a version 0; it has little

more in it than the Check Out status information.

Canceling a Check Out

In a multi-user environment, there are times when you check out a file that you are not going to edit, or

you want to discard edits that were made. This does no harm unless someone else needs to edit the file, in

which case you need to release the file. This is done using the Cancel Check Out command.

Scenario 1 Unedited files

In this example, all the files composing the assembly were

checked out. Three files were edited and saved, two files

are from a library, and the rest were not edited.

Using the context menu, the Check Out of the trim washerand string postare canceled.


32/49


www.autodesk.com 32

Once you have canceled the Check Out, the files show as

available until someone else checks the file out.

If someone else does check the files out, you do not see this

reflected in the browser until you Refresh the File Status

browser, attempt to Check Out, Resolve status, or reopen

the assembly.

Scenario 2 Edited files

In this example, all the files composing the assembly were

checked out. Four files were edited and saved, two files are

from a library, and the rest were not edited.

Using the context menu, the Check Out of the small capand

casting2are canceled.

After canceling the Check Out, the files have a status of .

This status indicates that the assembly still reflects the edited

versions of the files that were checked out to your workspace.


33/49


www.autodesk.com 33

To see the correct version of the

files, the assembly Refresh

command must be used.

Alternatively, the assembly can be

closed and reopened.

Upon issuing the Refresh, the

assembly and the File Status

browser are updated.

The Check-In processWhen you are ready to post changes back to the server for others to see, the Check In command is used.

The Check In command has two forms:

Check In Used to check in a specific part.

Check In Tree Used to check in an assembly or subassembly, and all it dependents that were

checked out and edited.

The Check In command skips over all parts that were edited, but were not checked out.

Working with others

The status of files in a multi-user environment can be very dynamic. The essential value of Autodesk

Inventors multi-user functionality is that it assists users to avoid editing collisions. An editing collision


34/49


www.autodesk.com 34

is when two users are editing the same file simultaneously. Without edit collision aids, it is like a game

the last person to save wins! Unfortunately, the consequences of losing design data and impacting

time to market are real.

The following is a step-by-step workflow example using the multi-user environments semi-isolated mode.

Setup

There is a server, which is the central file repository. Located on the server is a Group Project File that

defines all file storage locations defining the repository. Each user has a personal workstation. Located

on each workstation is a Workspace Project File that includes the Group Project File and defines a local

Workspace. All files that are checked out from the server are located in the Workspace (usually on the

users personal workstation). The contents of a users workspace are not visible to the other users or from

the Group Project file.

Step 1

We start with two users, Rob and Paul. All the files currently defining the product design are located in a

workgroup search path on the server. Neither Rob nor Paul have any files checked out. One way to view

this is that all files are checked in to the server, which is how the figure depicts the situation.

Vault RobPaul

Step 2

Paul checks out the casting2and shaftparts. If Rob already opened the tunerassembly, he does

automatically see that Paul checked out some parts. To see the updated status, Rob uses the Refreshcommand on the File Status browser toolbar. Note: If Rob tried to check out either part, he would see

that the parts are already checked out by another user.


36/49


www.autodesk.com 36

Server RobPaul

Step 3

Rob checks out the large cap, small capand buttonparts.

Server RobPaul

Step 4

Rob edits the small capand buttonparts, which are checked out, but does not save the parts. The File

Status browser indicates the edited files by placing an asterisk (*) after the file name. Notice that thetuner is shown as edited. Why? Sometimes Autodesk Inventor makes edits to parts even though the user

does not explicitly make edits. In most cases, it is optional for the user to save the edits, but saving them

usually makes subsequent file opening faster as an assembly update can be bypassed.


37/49


www.autodesk.com 37

Server RobPaul

Step 5

Paul activates the shaft part in-place, and then makes some edits. When this happens, Autodesk Inventor

presents the following message box:

Once again, Autodesk Inventor made some edits to the tuner, but realized that Paul does not have it

checked out. Paul is informed that the edits will be made, but changes to the assembly will not saved.


38/49


www.autodesk.com 38

Server RobPaul

Step 6

Both Rob and Paul select the Save command. The Save dialog box lists the parts that were edited, and

which parts it intends to save. The following dialog box displays what Paul sees when the Save command

is invoked. It lists two files that are dirty. He is not the owner of the assembly tuner.iam, so it is not

saved.

Upon saving, the File Status browser indicates that the edits were saved to the workspace.


39/49


www.autodesk.com 39

Server RobPaul

Step 7

Rob and Paul are talking over lunch, and a decision is made for Paul to take over the design of the button.

Furthermore, Paul does not want the changes Rob made since checking it out. To relinquish the Check

Out of the button so that Paul can check it out, Rob must perform a Cancel Check Out operation.

After performing the Cancel Check Out operation on the button, it has a status indicating that Rob

canceled the Check Out of a file that he edited and saved to his workspace. The status indicates that he

still sees the version with the edits, and he must either use the assembly Refresh command or close and

reopen the assembly.

Server RobPaul

Step 8


40/49


www.autodesk.com 40

Rob uses the assembly Refresh command to see the button the way it was before he made the edit that he

subsequently cancelled. Rob finishes updating the large capand small capparts, and saves the changes.

Rob is ready for Paul to see his updates, so he Checks In the large cap, small cap, and tunerassembly.

Rob sends Paul an e-mail message letting him know the changes are up on the server. To verify this, Paul

uses the File Status browsers Refresh command, located on the toolbar. The three parts large cap, small

cap, and tunerindicate that there is a newer version on the server than what is currently displayed in the

assembly.

Server RobPaul

Step 9

Paul uses the assembly Refresh command to update the view of the assembly and the most current version

of each part up on the server. However, Paul has parts that were edited, but not saved. If the Refreshcommand is invoked, Paul is prompted to save the edited files.

Server RobPaul


41/49


www.autodesk.com 41

Step 10

Paul realizes that a few more parts are required. There are a couple of ways that new parts can be added.

Paul uses two methods. New Part 1is created using the assembly Create In Place command and is saved

to Pauls Workspace. When trying to create the part, Paul was prompted if he wanted to Check Out the

tunerassembly. New Part 2preexists on the server and is placed into the tunerassembly.

Server RobPaul

When a part is created with the Create In Place command, by

definition it has edits that need to be saved. Upon saving the file, it

gets a status of Unresolved .

When New Part 1 was created, it was initially saved to Pauls local

workspace. There is no copy of it on the server because Paul never

stated in which workgroup it will ultimately be saved, and as a

result no other users know of its existence.

As soon as Paul is fairly certain that he is going to keep the part in

some form, the Resolve command should be used. Resolve is

available from the context menu of a selected unresolved part.

The Resolve Check Out command allows Paul to specify where the file will be stored on the server and

creates a Check Outplaceholder file for the part on the server. The result of the placeholder is that other

users will know of the parts existence and cannot create a part using the same name.


42/49


www.autodesk.com 42

Step 11

Paul is done editing and is ready for Rob to see his changes and new parts. Paul uses the Check In Tree

command to Check In tunerand all its children that have been checked out. Rob uses the File Status

browsers Update Statuscommand to see the changes.

Notice that Robs File Status browser does not show the new parts. Why? Autodesk Inventor checks the

status of each open file. The tunerassembly that is currently open does not know about the new parts.

The new parts show up when the assembly is refreshed to see the latest version of the tunerassembly.

Server RobPaul


43/49


www.autodesk.com 43

Step 12

Lastly, Rob uses the Assembly Refresh command to see the files that Paul updated. Notice that the File

Status browser now shows the new parts.

Server RobPaul

Duplicate file names

In general, it is not a good idea for different files to have the same file name. In most cases, Autodesk

Inventor takes the first file it comes to as it looks for the referenced file in the active project. There is one

exception to this rule, Libraries.

What is a library? It is typically some collection of related data files that you reference but dont modify.Often the files come from third-party vendors that have their own file naming schemes. As a result,

Autodesk Inventor allows different libraries to have files with the same name.

What distinguishes a Library from other search paths is that you locate them in a separate folder with

which you associate a name. The name distinguishes these files from those that are specific to your

project and from other libraries. Autodesk Inventor refers to a library as aName Space. Within a given

library, each file must have a unique file name. However, different libraries can have files with the same

name.

When things go wrong

There are many scenarios where things do not go as planned, and there is a need to either steal a Check

Out from someone else, or cancel a Check Out. Lets look at some possibilities:

1. A user leaves the company, or for vacation, with files checked out.

2. Workspace files get lost due to deletion or perhaps a failed disk drive.

3. A network interruption at an inopportune time occurs.


44/49


www.autodesk.com 44

In these situations, you can use the Resolve command on any file that has a Check Out pending. When

issued, the following dialog box is displayed and provides options to either Steal Check Out or Cancel

Check Out.

A Cancel Check Out makes the file on the server available for Check Out to anyone. The user who

previously had it checked out still has the file in their workspace with whatever changes were made and

its status eventually changes to unresolved (the Check Out can be stolen back). The Steal Check Out is a

combination of a Cancel Check Out and a Check Out, except that the person you stole the Check Out

from is an unknowing participant, and may have cleanup work to do as a consequence. It is best to avoid

using Steal Check Out unless there are no alternatives.

Autodesk Inventor Content Library

The Autodesk Inventor Content Library allows the

user to specify where generated files that represent

standard content should be stored. The storage

location is defined by selecting the Configure

button on the Content Library browser.


45/49


www.autodesk.com 45

By default, the Content Library store files with the Parent Assembly. This is an appropriate setting when

the multi-user option is turned off. If the multi-user option is set to Shared or Semi-isolated, then it is

required that a library be defined as the storage location.

Case studies

Case 1: Single user

The simplest of single user setups uses an

unaltered Default project file. Each design that is

worked on is stored in a separate folder. There is

no sharing of files between designs. If a design

needs to use a part in another design, the part is

copied. Alternatively, all designs are stored in a

single folder.

Default Project


46/49


www.autodesk.com 46

Case 2: Single user with libraries

This scenario also uses the Default project,

but the project is edited to contain two

Library definitions.

The user can hop around from design to

design, and always have access to a shared

set of common components.

Default Project

Fastenersc:\fasteners

Purchased

Partsd:\purchased

Case 3: Advanced single user

In this scenario, the user creates a project file for each design that they are working on. The project file

contains the two libraries and two workgroup search paths. The addition of the workgroup search paths

allows for file references to cross-folders, which do not have an ancestral relationship.


47/49

C:\D1\ABC C:\D1\XYZ

E:\D2

E:\D2\ABC E:\D2\XYZ

Design_1.ipg Design_2.ipj

Purchased Partsd:\purchased

Notice that the Workgroup search paths point to folders that are subfolders of where the Project File is

located. This allows the design to easily move from one location to another without having to edit the

Project file.

Case 4: Multi-user in semi-isolated mode

Following is a recommended procedure for setting up a team to work in semi-isolated mode.

1. Define a location on the server where the different workgroup storage locations will reside.

Create a subdirectory for each storage location.

2. Define the locations for all libraries. These may be on the same server as the workgroup storage

locations or on different servers.

3. Create a group project file that defines the workgroup storage locations and libraries. Set the

Multi User option to Semi-Isolated.

4. Decide on a workspace location for each users machine and create the required folder.

Administrative costs can be kept to a minimum by using the same location on each users

machine. Create a project file that includes the group project file and defines a Workspace that

points to the appropriate location on the users machine. Store the project file on the server in the

same location as the group project file.

5. Start up Autodesk Inventor on each users machine and bring up the Project Editor. Select the

Browse button and the Choose Project File dialog will appear. Select the user project file,

user.ipj, located on the server. The result will be a new entry in the Project List.

6. Make the new project the active project.

Case 5: Single-user in semi-isolated mode

The semi-isolated mode of operation can add value even for a single user. In this situation, the user is notmaking use of collision avoidance, but simply the ability to isolate in-work changes from the baseline

design. By not making changes directly to the baseline design, it is easier to cancel a design change if it

does not work out as expected. All the user has to do is a cancel Check Out.

This is the only situation where it can make sense for a single project file to contain both Workspace and

Workgroup definitions. Even in this scenario, there may be merit to using a separate workspace project

file that includes a group project file.
