Introduction to Pro/DESKTOP V8Pro/DESKTOP is a feature based solid modelling and assembly modelling package with aninbuilt feature-based drafting package designed to run on a PC.

Version 8 differs from previous versions as it is built on the same platform as Pro/Engineerand because of this files can now be transferred between these two packages.

The software has three major parts to it being 3D Design, 2D drafting and a 3D Album orvisualisation package.

All three parts of the software interact and changes made to one effect the others. This is themeaning of Parametric Design.

The first package we will look at is the 3D design.

Pro/DESKTOP can be controlled using descriptive menu bars or by selecting the optionsfrom regular windows pull down menus.

Other useful Pro/DESKTOP features

Pro/DESKTOP has comprehensive help tutorials available. These can be used in conjunctionwith this manual to help understand the software. These tutorials can be found under thePro/DESKTOP help menu.

Other useful features within Pro/DESKTOP are the View and Zoom options availableusing the centre mouse button or scroll bar.

Press and hold the centre button when looking at a design and the drawing can bemanipulated: • By holding down the mouse centre button and moving the mouse the design is

rotated • Press Shift and then left click the centre button and the design is dragged on the

screen • Press Ctrl then click the centre button and you can zoom in and out. • Press Ctrl and Shift then click the centre button, this gives a rotate function. • By rolling the scroll wheel the zoom function is also obtained.

Selecting Lines, Edges, Faces or Components

There are some simple rules when relating to selection within Pro/Desktop which arecommon to all areas of the software.

It is important to understand these rules before you proceed with the rest of the course.

When selecting any line, edge, face, component or in fact anything within the software theselection tool must first be found and selected from the Design toolbar.

Once this is selected, move the cursor over the item to be selected and you will see it turnsBLUE. This means it is PRESELECTED. The item coloured blue will be selected if youclick the mouse.

Once you have clicked the mouse, the line, edge, face or whatever you selected will now becoloured in RED. Red indicates an item is SELECTED.

If you now want to drag or move the item you move back over it with the cursor and wait forthe cursor to change to indicate the item can be manipulated.

Features, Sketches and Workplanes

To be able to use Pro/DESKTOP you must have an understanding of Features, Sketches andWorkplanes.

Workplanes

The best way to think of workplanes is to think of them as drawing boards. If you want todraw on a face of an object or anywhere in a design first you need to create a workplane ordrawing board. When you open a new design, you get 3 workplaces by default. They are theBase, Frontal and Lateral.

Sketches

Sketches are like sheets of tracing paper and are placed on drawing boards. You cannot have a sketch unless it is on a drawing board or Workplane.You can have multiple sheets of tracing paper or sketches on the same drawing board.When you are drawing on one sketch, you can see the lines drawn on other sketches.The active piece of paper or sketch is always highlighted in black in the sketch list.

Features

Features relate to solids within a design.

A sketch is used to define a feature. If you create a feature from a sketch then any changes made to that sketch in the future willchange the feature.If the sketch is deleted the feature will no longer be able to exist.

General Rule

When looking at the menu bars on the screen you will notice that several of the icons arecoloured yellow.

Yellow icons refer to Solids or Features. They allow you to create a feature or select a face,edge or part of a feature.

BOXFORD


Course Tutorials


Example: Sketches and Features

If you open a new design then draw a rectangle this is a sketch. The shading or “fill”indicates that the “Sketch is Valid” or is OK to use to create an extrusion.

With a new design there is an initial sketch created on the base Workplane by default. Bylooking in the Workplane design tree you can see the active sketch is called initial and islocated on the base Workplane.

If a sketch is NOT VALID because lines overlap or the profile is not a closed boundary thenthe shading is not shown. The sketch is invalid and must be corrected before you try to makea feature from it.

Invalid Sketch Valid Sketch

BOXFORD


Course Tutorials


If you draw a rectangle then extrude it the resulting solid is a Feature and appears in theFeature list at the top left of the screen.

You can reselect a Feature and modify it from this Feature List.

As designs are created you can select any feature in the list and redefine it at any time.Once the feature is changed you must refresh the design for the change to take effect.

If you now draw a circle it will be added to the active sketch, which is in this case the initialsketch.

The Extrusion we defined is applied to all items drawn on the initial sketch, so as soon as weadd to or modify the sketch the Green refresh light comes on. This indicates that the sketchdefining a feature has changed and so the design needs to be updated.

If we click the Update light the design is updated and the modified feature is shown.

Example 2: Creating New Sketches and Workplanes

When you create a new design the software automatically creates three Workplanes and addsa sketch to the base Workplane.

If we draw a rectangle on the initial sketch on the base Workplane and extrude this up we nowhave a block.

If we wanted to draw another item and extrude it higher than the block we have we mustcreate a NEW SKETCH to define the new feature.

If we add to the existing initial sketch then whatever we draw will be extruded to the sameheight as the block.

Add a sketch to an existing Workplane

We need to add a sketch to the base workplane. This is like adding another sheet of paperonto the base drawing board.

To do this move the cursor over the Workplane folder named base and Right Click themouse. Select New Sketch

Course Tutorials


You can now draw some additional geometry on the new sketch and create a new extrusionusing the new sketch. The sketch can overlap lines on other sketches an will remain valid.

The new extrusion can be any height.

The Workplane tree and Feature tree show the additional sketches and features.

Add a sketch and create a new Workplane

If you want to draw on the top of the cylinder we need to add a sketch to the top face of thecylinder.

To do this we must create a workplane or drawing board on this face and add a sketch or sheetof paper to the drawing board.

If you try to add a sketch to a face where there is not already a drawing board thenPro/DESKTOP will automatically create this for you.

Tutorial 1 Dimensioning

When you are designing in Pro/DESKTOP it is important that you dimension your sketches.

The dimensions within the Design package are used in the Drawing package also and enablethe design to be changed at any time.

There are several ways to dimension parts some of which are shown below.

It is good practice to select a reference line and dimension everything in relation to this.

Below is a sketch that has been drawn freehand which we will now dimension. Thedimension tool is located on the constraints toolbar as shown.

A Reference line is selected. To do this move over the line with the Dimension tool and theline will be pre-selected and coloured blue. Click on the line to select it, the colour willchange to red to show it is selected.

Now move the mouse to select the line that we will dimension to. Note as you move over theline the cursor changes to show a dimension tool and the line to be dimensioned is pre-selected in Blue. Click on the line and hold down the mouse button and drag the dimensionaway. Release the mouse to drop the dimension.

Repeat for other edges

Select the Left hand edge as a reference then dimension the vertical edges.

Course Tutorials


Dimensioning a Circle or an Arc

First you must ensure no reference lines are selected (if they are, click the mouse away fromany line). Move over the arc and it will pre-select in Blue.

If you want to dimension a Radius value, then, whilst the arc is pre-selected click and holdthe mouse button and drag the dimension away.

If you want to dimension as a Diameter value, first select the line, then when it is selected,(red) click on it and drag it away.

Dimension to the centre of a Circle or an Angle

When dimensioning the centre of an arc or circle you must first highlight a reference line byselecting it and ensure it is coloured red.

To select the centre of a circle you have to move the cursor to a position just inside itsdiameter and then you will see a black square appear marking the centre. When the blacksquare is present any dimensions will snap to this point.

Pre Selected Arc Arc selected then dimensioned as Dia

Tutorial 3: Transform

The transform feature allows vectors (lines in a sketch) to be moved, rotated or scaled inrelation to the origin.

Any constraints applied to the sketch prior to transforming the object will take priority overthe transform command.

Notes: If components are linked to other components with any constraints then the transform feature effects both components.If lines are dimensioned, this will override any attempt to scale the lines.

Create a new design. Draw a rectangle starting from theorigin

Draw a circle inside the rectangle as shown. The size isunimportant

Ensure the circle is selected (RED).

From the Edit menu select transform

With the translate option selected type (12,12) then OK.

The centre of the circle will move a 12mm away fromthe Axes in both the X and the Y axes. If you type 12,12once more and OK, the circle will move a further 12mmaway from the Axes.

Shift the circle back to its original position with acommand of (-24,-24).

Select all the items on the drawing, then select Edit, transform and rotate. Type in an angle of 45 degreesand the whole part rotates around the axes by 45 degrees.

Tutorial 7 Revolve

The revolve feature allows a profile to be revolved about an axis.

The profile must be a closed shape that is valid (shaded).

It is possible to revolve around a workplane that is perpendicular to the profile.

It is possible to rotate around a solid edge of a feature in the same plane as the profile

It is possible to rotate around a straight line in the profile sketch or a line on another sketch onthe same workplane.

Revolve about a Line

A construction line can be drawn as an axiswithin a sketch containing a profile.

Draw a profile as shown. Ensure that theprofile is filled to show it is valid.

Draw two straight lines as shown

Draw the lines then when they are selected(coloured red), right click the mouse andtoggle them to be construction lines.

These lines can be used as axes and providingthey are construction lines, do not make theprofile invalid.

Select the Revolve feature.

Select the sketch name you have drawn theshape to be revolved in as the profile.

The control box that appears defaults to 360degrees rotation.

The axis tool defaults to lines. Select thevertical line on the left hand edge of the profile(where the Axes are located) and click OK.

Right click on the revolve feature in the feature list at the top left of the screen.Select Redefine.

Tutorial 8 Swept Profile

The sweep feature allows a profile to be swept (extruded) along a path.

This allows a profile to be extruded but to change direction along its path.

A sweep requires two sketches one to be used as the profile and the other to be used as thepath along which the profile is to be swept.

Draw a rectangle on the base workplane Initial sketch and extrude it upwards.

Select the front face, then create a new workplane and sketch upon it.

Call the workplane front face and the sketch Profile.

Draw a Circle on the Profile sketch positioning it at the top left hand corner of the face.

Select the sweep profile option from the feature toolbar or feature drop-down menu.

Select the sketch to use as profileto be Profile.

Leave the Add Material checked.

If the initial sketch is used as the path then the profile will be swept around all four sides ofthe block.

BOXFORD


Course Tutorials


If additional profiles are added to the profile sketch then the update light will become greenand the sweep will effect the new parts of the profile.

The path used for the above sweeps has been the initial sketch. It is possible to add a newsketch to the design and create a new path.

If the profile was only required on 3 sides of the block then the path would only be drawn on 3sides.

Select the top face of the block. Make a new Workplane called topand a new sketch called Path.

Draw the following path on top of theblock.

Put a radius in both the corners.

Tutorial 9 Loft Through Profile

The loft feature allows a design to be produced moving through several workplanes. It allowsparts to be designed that change from profile to profile.

To be able to draw the sketches required to produce a loft, a series of workplanes and sketcheshave to be created.

So far we have used just the Workplanes that are created automatically when a new design isopened or Workplanes have been added to the faces of a component already defined.

In this tutorial we will create Workplanes and add sketches to them before defining thesketches to make the feature.

Open a new design.

Go to the workplane menu and select Newworkplane.

Several options are available for creatingworkplanes. Select Offset.

The workplane can be offset from any workplanethat already exists by selecting the workplane first.

Create a new workplane, offset by 50mm from thebase.

Click OK.

Note the new workplane is now the activeworkplane.

Repeat the process of adding workplanes with anoffset of 50mm.

The new workplanes are added as shown, offset50mm from the previous plane.

Tutorial 13 Assembly

Using Pro/DESKTOP it is possible to assemble parts together. There are several commandsthat are used and examples of these are shown below.The constraints put onto the components as they are assembled are listed in the tree at the Leftof the screen and can be checked, deleted and redefined.

When assembling parts ALWAYS START WITH A NEW DESIGN.If you open up a design of a part and add other parts to it then when the design is saved theother components become part of the design.

Selecting a Part

When components are added to the design they can be selected with the Parts select tool fromthe “Design toolbar”

Move over the part and it will pre-highlight in blue. Click the part and it is selected in red. Move back over the part and the cursor changes to a drag icon. Click the mouse and hold down and the part can be moved.

Open a new design.

Check the very top menu bar to see that the part name says New Session and has a defaultname. (This confirms that we are starting an assembly and are not adding parts to a componentdesign).

Go to the Assembly drop-down menu and select add component. Find the box component andselect it. Now select add component again and add the lid.

The components will be displayed as shown.

Select component option in the drop-down menu at the topleft of the screen and you will see both parts displayed.(Choose component rather than Workplanes or features)

Mate(This function pulls two faces together face to face)

To make the top fit onto the top of the block the two facesmust be mated.

Use the face selector tool and select the bottom face of thelid. Hold down Shift and then select the top face of theblock so both are highlighted in Red.

Right click the mouse and then select the Mate option.

The box and lid are shown mated together.

When two faces are mated they will touch face to face.(The two components can be slid apart but the facesremain in the same plane)

Align(When 2 parts are aligned, the selected faces are both in the same plane facing the same way) The align command will be used to line up the side faces of the box with the side faces of thelid.

The two faces of the box and lid have been selectedtogether. (Hold down the shift key to allow both faces tobe selected)

Right click the mouse and select Align.

Now select the other 2 side faces and align them also.

Centre Axes(this function centres cylindrical faces down the centreaxis)

Add a new component called “wheel”, Move the wheeland rotate the box so that the holes in both are visible.

Highlight the faces of the holes as shown.

Right click the mouse and select Centre Axes and thecentre line of the two holes will line up.

BOXFORD


Course Tutorials


If the wheel is selected and dragged, it now follows the line of the axis hole.

If the wheel is selected and dragged it is now constrained on the centre line. It can be movedcloser to and further away from the box and can also be rotated.

Offset (The offset command allows parts to be assembled using both mating or aligning constraintsbut adding an offset or gap between the faces either + or -).

By selecting the face of the wheel nearest the box and the front face of the box, an offset matecan be created, which will make the wheel remain a fixed distance from the face of the block.

In this case we have used an Offset Mate with a value of 20mm which will keep the wheel20mm away from the face of the box (also maintaining the centre line of the holes).

Orient(The orient command is used for a rotary (angular) constraint)

The angle of the faces in the slot in the wheel can be set to an angular dimension from any faceof the box.

Wheel centred on hole Wheel moved on centre line

Editing Constraints

Once parts have been assembled the constraints are in place. If a constraint is placed in thewrong place or is over constraining a component they can be edited or deleted.

To view the constraints on a part select the Component list and select the part in question. Byhovering the mouse over a part in an assembly it can be identified.

Once the part is selected in the parts list there is a list of constraints displayed below.

To be able to see these constraints easily it is best to display the assembly in theTRANSPARENT mode. Once the assembley view is transparent then select each constraint inturn by left clicking the mouse over it in the list.

The Lid in the TIC TAK TOE assembly has thefollowing constraints.

The Centres relate to the hole in the lid and the hole inthe Hinge.

The Drawing Package

Within Pro/DESKTOP there is a conventional 2D drawing package where blueprint drawingsof the designs can be obtained. The dimensions given in the 3D package can be automaticallyimported and are used to Parametrically link the 2D and the 3 D designs.

This allows a dimension given in the 3D design package to be altered within the 2D part of thesoftware and both drawings are dynamically linked and changed together.

The Drawing Program is started by selecting file new then Engineering drawing.

You must decide if you want to open a template or ablank sheet. If you want to open a blank sheet thenyou must first browse for the document to open. Thereare templates or blank sheets that can be selected.

There are also 3 other options of New Design, Designin Session or open an existing design.

If you select one of the templates you can then selectone of the open designs and it will be imported anddistributed on the sheet.

It is also possible to browse for a blank sheet and opena new empty design.

If you open a design in session then both a drawing window and a design window are openedtogether so you can design then import the design into the drawing.

Which ever way you open an engineering drawing the menu bars and tools work in the sameway.

Select New Engineering drawing.
