2.2 General

Improvements in concrete detailing

To better fulfill the various requirements in cast-in-place and precast detailing practices, TeklaStructures 17.0 contains changes in concrete detailing.

The following changes have been made for cast units in concrete detailing:

Family numbering is only applied for precast cast units. The top-in-form setting is only taken into account in the numbering of precast cast units. Precast components can only be applied for precast cast units. Precast manufacturing exports are only allowed for precast cast units (for example,

Unitechnik, ELiPLAN).The following improvements have been made in the Reinforced Concrete Detailing (RCD) configuration:

Cast-in-place cast units and reinforcements can now be numbered in RCD . When reinforcing precast concrete parts, conceptual reinforcements are created in RCD . It

is possible to convert the conceptual reinforcements to detailed reinforcements in thePrecast Concrete Detailing (PCD) configuration.

You can now add steel embeds to cast-in-place cast units in RCD . You can now warp, camber and shorten a part using the options on the Deforming tab in

the part properties dialog box in RCD . It is now possible to create cast unit drawings of cast-in-place cast units. Precast cast unit

drawings cannot be created, and the existing drawings are only in read-only mode in RCD .

Improvements in snappingThe following improvements have been made to snapping in Tekla Structures 17.0:

When snapping to extension lines, it is now easier to follow an extension line as it extends past the cursor.

Cast units have the cast unit type part property - they are set either Castin place or Precast . It is now important to use the correct cast unit type,

because some functionalities, for example numbering, are based on thecast unit type.


13/68



When snapping to an extension line that is perpendicular to the part reference line, anangle symbol is shown.

When both the Snap to extension lines snap switch and the Snap to nearest

points (points on line) snap switch are active, it is now possible to snap to theintersection of the extension line and the grid line. Snapping to the intersection also works

when both the Snap to extension lines snap switch and the Snap to intersection

points snap switch are active.

It is now easier to find the extension line in 3D view when snapping. To show theextension line, you can move the mouse pointer along the part reference line and continuein the direction of the extension.


14/68


The Snap to nearest points (points on line) switch and the Snap to lines and edges

switch are now next to each other in the Snapping toolbar . They have beengrouped so that turning one of them on automatically turns the other one off.

For moreinformation

Snapping to extension lines

Improvements in Mini Toolbar The following improvements have been made to the Mini Toolbar in Tekla Structures 17.0:

You can now quickly show or hide the Mini Toolbar using the keyboard shortcut Ctrl+K .You can still also go to Tools > Options > Mini Toolbar to show or hide the toolbar.

You can now modify polygon welds using the Mini Toolbar .For moreinformation

Mini Toolbar

Font used in Tekla Structures user interfaceThe font used in the Tekla Structures user interface now follows the Windows default systemfont. If you change the system font in Windows, the font used in Tekla Structures dialog boxesand other user inteface elements changes accordingly.

Using the Windows default system font makes the user interface more easy to read.

Improvements in using l ists in dialog boxesWhen selecting options from a list in a dialog box, you can now point to the list you want todisplay, click and then enter one or two characters to find the desired option.

Previously, you had to open the list and then drag the pointer to highlight the desired option.

15/68



Improvements in FLEXnet licensing

Tekla Structures 17.0 works with version 17 entitlements. You need to deactivate version16 entitlements in order to activate the version 17 entitlements.

New version of Tekla Structures license server is released with Tekla Structures 17.0. Theversioning of Tekla Structures license server has been harmonized with the TeklaStructures version numbers. From now on the version number of the licensing tools refersto the Tekla Structures main version, same way as the entitlement version number.

Tekla Structures Licensing Service is now configured automatically during the licenseserver installation. Your server computer hostname is automatically written intotekla.lic license file, and the license server manager lmgrd is set to run TCP/IP port

27007. This reduces the need to edit the tekla.lic file manually.

There is a new tab in Tekla Structures License Administration Tool . The Statistic tabshows the license usage at one view. The Statistic tab gives the total number of eachconfiguration activated on the server, licenses in use, borrowed licenses and free licenses.

Tekla Structures 17.0 beta versions work with version 16 entitlements.


16/68


The usage of the enterprise licenses can now be controlled through tekla.opt optionsfile. You can, for example, assign the enterprise licenses to a certain work group with thefollowing rule:INCLUDE STD-E GROUP detailers-india

The configuration code of Construction Management has changed fromConstructionManagement to CM-C. You can use the new configuration code intekla.opt file to control access to Construction Management licenses.

You can now run Tekla Structures license server without troubles with VPN connection.

Global and local folder for XS_MACRO_DIRECTORYThe advanced option XS_MACRO_DIRECTORY in Tools > Options > Advanced Options... >File Locations now accepts two folders: a global and a local macro folder, and finds macros inthese two folders. Use a semicolon (;) as a separator. Do not define more than two macrofolders.

First define the global folder and then the local folder:XS_MACRO_DIRECTORY=%XSDATADIR%\environments\common\macros;%XSDATADIR%\environments\\macros

In the Tools > Macros dialog box, you can select which macros to run by selecting the Local orGlobal option button. The buttons are not visible if you specify only one macro folder.

Please do not change the global folder. If necessary, you may change thelocal folder.


17/68


18/68


You can define a specific color of your own for each object group. When you click Choosecolor... , the Color dialog box is displayed. You can select a color either from the Basic colors

palette, or create custom colors of your own.

You can use an unlimited number of colors in a model. The Color list in the ObjectRepresentation dialog box shows 10 previously defined colors above the dashed line.

Information about the colors that you set for the object groups is stored in theused_custom_colors.clr file, which is located in the model's attributes folder.

Information about the colors that you add in the Custom colors palette is stored in thexs_user.xxx file in the model folder ( xxx is your user name).

Changes in view type selectionThe View type selection has been removed from the model View Properties dialog box. Allmodel views are now by default rendered.

If you want to use wire frame, set the advanced option XS_ENABLE_WIRE_FRAME to TRUE through Tools > Options > Advanced Options > Model View .

Rendered views:

The Autostick options in the Display dialog box are unavailable.Wire frame views:

The View type selection is available in the View Properties dialog box, and you can setthe view type to rendered or wire frame.

The Autostick options are available in the Display dialog box.Both rendered and wire frame views:

The command Create Zoom Window has been removed from the View menu. You can usethe zooming commands Zoom In and Zoom Out instead of Create Zoom Window .

View types

New tools for creating surface viewsWith the new surface view creation commands you can pick the surface of any part, and TeklaStructures automatically creates a new aligned temporary view looking directly at the surface,fits the work area of the model to the selected part, and aligns the work plane to that surface ora user-selected edge of the surface. This makes it easier to model in bolt groups, stiffener

plates, and hole penetrations on complex geometry. While you model in the newly createdtemporary view, you can see your modeling work being done in the original 3D view forverification.You can also use these tools to easily create views along the surface of concrete

panels, slabs, columns, or beams, which makes it easy to place embeds, formwork, or wall

penetrations.The commands are available in the Macros dialog box ( Tools > Macros ), and you can also addthem on a toolbar ( Tools > Customize ).

To create a surface view using the toolbar:

Choose color is not available in Tekla Web Viewer. If you intend to publish the model as a web page, use only standard colors.


20/68


1. Click one of the view creation commands: To create a surface view from the part surface, click CreateSurfaceView and select

the surface of a part you want a new view to be created from. If creating the surface view from only selecting the surface does not align or orientate

the view along the edge you might want, click CreateSurfaceView_wEdge , select thesurface, and pick the edge in which you want to align the view to (this means the edge

that will form the X axis of the view).

Ensure that you have Snap to geometry lines /points on. This allows you to pick along an edge to define the direction.

Tekla Structures creates a new temporary view with the view plane at the selectedsurface and the work plane changed along typically the longest edge of that faceunless you chose the CreateSurfaceView_wEdge command.

2. Once the view is created, press Esc or right-click and select Interrupt to interrupt.3. Use t he command WorkPlaneGlobal to return the work plane in the model back to the

origin and aligned with the global X,Y, and Z planes of the model.

Example Below is an example of a view that has been created with the CreateSurfaceView command.

Below is an example of using the CreateSurfaceView_wEdge command. The first image

shows the snap to lines arrow. The head of the arrow represents the positive direction the x axiswill be set to on the work plane. The view will be rotated to this direction in order to form theflat horizontal edge of the view. The origin of the view and work plane will be at the start of thearrow snap line. Once you have hovered over the edge and in the correct direction, click yourmouse and the new view will be created and aligned to that edge.

2.4 ReinforcementDefining your own reinforcing bar bending shapes

In Tekla Structures 17.0 you can define your own custom reinforcing bar bending shapes withthe Rebar shape manager tool. Custom bending shapes are useful when Tekla Structures doesnot recognize a reinforcing bar bending shape and assigns it UNKNOWN bending type.

The custom bending shapes can be used in bending schedules and pull-out pictures in the sameway as the predefined, Tekla Structures internal bending shapes.


22/68


To define your own reinforcing bar bending shape:

1. Set the advanced option XS_USE_USER_DEFINED_REBARSHAPERULES to TRUE to enablethe user-defined bending shape recognition.

2. Select reinforcing bars in the model.3. Go to Tools > Macros... , and select RebarShapeManager .4. Click Run .

Rebar shape manager opens, and lists the selected reinforcing bars on the Model rebars list.

Model rebars list shows the ID number and the bending shape code of the reinforcing bars. If the bending shape is not recognized, three question marks ??? are shown.

5. Select one unknown shape from the Model rebars list.6. Define the needed bending shape information.

Bending shape rules lists the rules for the bending shape. You can add or a delete arule by clicking the plus and minus buttons.

Use the Shape code box to enter a shape code for an unknown shape.If you have defined the shape code for a selected reinforcing bar and you havemodified the shape code, bending shape rules or the bending schedule fielddefinitions, click Update to update the existing shape code defintion.

Select the Require hooks check box if you want to define different shape codes fortwo bars that have been modeled with or without end hooks but still have exactly thesame geometry. By default, the hooks are not required and the check box is notselected.

Use Bending schedule fields to define the content for a bending schedule. Right-click a field to select the shape properties, or to enter a formula.

Alternatively, you can first open Rebar shape manager and then selectreinforcing bars in the model.

Click Get selected to add the reinforcing bars to the Model rebars list.


23/68



7. When you have finished defining the new shape, click Add to add the bending shapedefinition to the RebarShapeRules.xml file.

8. Click Save to save the RebarShapeRules.xml file.

By default, the file is located in the ..\TeklaStructures\\environments\\system folder.

Next time you create, for example, a bending schedule, Tekla Structures uses the updated bending shape information and recognizes the added bending shape and assigns a correct bending shape code for it.

2.5 Drawings

Improvements in associativity and cloningThe following improvements have been made to associativity and cloning in Tekla Structuresversion 17.0.

3D views in GAdrawings

Objects are now associative in 3D views also in general arrangement drawings.


25/68



Intelligentcloning

Intelligent cloning is now enabled by default. This means that dimensions, marks, welds,texts, associative notes, and graphical objects are adjusted per their associations duringcloning. The advanced option XS_INTELLIGENT_CLONING_ALLOWED is not availableanymore.

TT52695

Views View frame is now updated if necessary when additional dimensions are created for new parts during drawing update or cloning. View frame is the gray box around the view.TT53592

Now the view boundary of main views is enlarged if necessary when new parts are addedto an assembly, or when a cloned drawing contains more parts than the cloning template.View boundary is the dashed frame around the contents of a drawing view.TT53980

Sometimes section views and detail views expanded in cloning. This was caused by theview boundary becoming too big. If the view was associated to a reinforcement bar in thecloned drawing, sometimes a wrong reinforcement bar was used, which caused the view toexpand. This has now been fixed.TT56952

A new advanced option XS_DETAIL_VIEW_MAX_GROWTH was added in Tools > Options >Advanced Options > Drawing View . The default value is 1.2 that prevents the view fromgrowing more than 20%. If you set this advanced option to 0.00 , the view size does nothave any upper limit.TT56952

The view placing during drawing update and cloning has been improved. Now viewsretain their relative location to other views better when view sizes change or when thedrawing contains lots of views.TT53547

When cloning, if there are new single parts in the resulting drawing, single-part views arenow created correctly for the new parts.


26/68


TT36256

Views for included single parts are now placed correctly after cloning and when you selectCreate single-part views from the pop-up menu.

TT54623

Dimensions The new advanced option XS_DRAWING_COMBINE_ADDED_DIMENSIONS controlswhether added dimensions are merged to existing ones in updated or cloned drawings.

Added dimensions are not merged to existing ones if this advanced option is set to FALSE through Tools > Options > Advanced Options > Drawing Properties . The default valueis TRUE.TT50191

Internal bolt dimensions of added bolts were sometimes missing after drawing update.This has now been fixed.TT53653

Bounding dimensions (first and last dimension points) are now cloned correctly. Theywere sometimes missing from manually added reinforcing bar dimensions in cloneddrawings.


27/68



TT50695

Dimensions located on the drawing sheet are now cloned to new drawings.TT54624

Duplicate dimensions are no longer created for bolts in updated or cloned drawings.TT54308

All obsolete dimension points are now removed after update or cloning. Previously, not allobsolete dimension points were removed, especially if the point was located near thecenter plane of the main part.TT55233

Now angle dimensios are correct after intelligent updates.TT50456

Dimension tags sometimes disappeared when dimensions were merged, or when moredimension points were added to the dimension line. This has now been fixed.

TT55232

Leader lineanchor points inmerged weldmarks

Merged weld marks now maintain leader line anchor points in cloning. Earlier straightlines were drawn.


28/68


29/68



Below is an example of ghost associative symbols. The ghost symbols are shown even thoughthe dimension is not selected.

In the image below, the selected 2'-8 dimension line has two associative symbols shown, and

the selected 4'-0 dimension line has a ghost associative symbol indicating that it is notassociated to anything.


30/68


31/68



The example below shows a tag that automatically contains concrete parts.

In the example below, a drawing view filter concrete is created.

The created drawing view filter was used to remove all concrete parts from the tag content.

4. Pick the first point to specify the origin of the dimensions. The origin is the point fromwhich you want to measure the location of the center of gravity. This point must be locatedwithin in the view frame.

5. Pick the second point to place the dimensions. This point may fall outside the view frame.

6. When the dimension is selected, handles are shown at the dimension origin and thedimension location. You can drag these handles to adjust the origin or the location, ormove them using the standard editing commands.


34/68


Limitations If a drawing containing COG dimensions is copied or linked to another drawing, such as amultidrawing, the COG dimensions will not be copied.

COG dimensions cannot be created in general arrangement drawings or multidrawings.

Adding dimensions

New tool for dimensioning spiral stirrup reinforcement groupsYou can now add dimensions to spiral stirrup reinforcement by using the CreateStirrupDimPlugin application.

Creating the dimensions successfully with this application requires that you model thereinforcing bar group using the creation method By exact spacings in the Reinforcing BarProperties dialog box.

Before you can use this feature, add the Create StirrupDIMPlugin command to a toolbar or tothe User menu through Tools > Customize .

To add the dimension, select the reinforcement, click the command Create StirrupDimPlugin that you added on a toolbar, or select the command from the User menu, and then pick alocation where you want to place the dimension.

Layout Manager - new tool for using model data on site

Layout Manager makes it possible to use accurate model data on the construction site.You can export model data from Tekla Structures to an external device, Trimble LM80, andimport data from Trimble LM80 back to Tekla Structures.

Using real model data on the site brings considerable improvements to construction productivity and accuracy. There are fewer errors as you do not need to manually calculatedistances and angles from plans, and, for example, pull tapes to measure distances.

To start Layout Manager , go to Tools > Layout Manager... .

To export model layout data, you need to define layout points and/or layout lines in yourmodel. You can define them using the LayoutPoint and LayoutLine tools in the Componentcatalog. When you have defined the points and lines in the model, refresh the view in LayoutManager to be able to manage the layout points and lines. You can for example, create groups,name the groups, and define the point class, size and shape.

Improvements in IFC import and exportThe following improvements have been included in the IFC import and export functionality inTekla Structures 17.0:

Otherimprovements

The top-in-form setting is now taken into consideration when exporting wall products.This change affects plotter data (the coordinate values for openings and embeds) of walland sandwich wall product types.

The total thickness of walls is now calculated for sandwich elements in the followingmanner:

Width (W) and height (H) are calculated based on extreme dimensions of all concrete parts of the cast unit. The origin for the plotter data is the lower left corner of the W*H box.

Thickness is now calculated based on extreme dimensions of concrete parts whosearea is 25% or more of the gross area of the whole cast unit. This way corbels or anyother small parts are not counted in the thickness.

Openings of all larger plates are exported in the plotter section. Earlier only main partopenings were exported.
