Introduction to Pro/ENGINEER

®

This training course will incorporate the opportunity to gain accreditation in the new Pro/ENGINEER software currently being rolled out by the Design and Technology Association. This 3D solid modelling package incorporates powerful CAD capabilities that are used by design and engineering industries and forms one of the largest communities of users for any 3D CAD system worldwide.

Course Outline:

Session One:

Course aims and introduction New developments in CAD CAD modelling with Pro/ENGINEER including:

• Pro/ENGINEER interface

• Introductory features

• 2D Sketching

• 3D feature based modelling

• (extrude / shell / revolve etc’)

• Assembling components

• File management

• Software licensing and deployment

Pre-Course Tasks: Before starting this training you should study the Pro/E Competency document to assess your existing understanding and capability in this area. This is a useful exercise in helping you to establish what you already know, don't know and will need to know in this area of the Design and Technology curriculum. You will be asked to complete an 'initial needs analysis' when you receive the Resource DVD from The Design and Technology Association including some pre-requisite reading.

Accreditation: Successful completion of this training course and the associated tasks will provide individual teachers with a 300 seat copy of Pro/ENGINEER, Wildfire 3.0 Schools Edition. The schools education license covers use at school and by teachers and students at home for educational purposes. Only teachers who have attended training and progressed through to accreditation by completing the Post-course assessment tasks are licensed to use the software in schools.



Before starting any new design, you need to make sure that the file you are about to use is going to be saved in the right place. To do this we need to create a new folder and set this as the working directory. The files you create and save will always be stored in whatever is set as the current working directory. It is therefore important to set the correct working directory at the beginning of each session so that all files are stored where you want them to be. When you open Pro/ENGINEER at the beginning of a session, you will see the Pro/ENGINEER Resource Centre page. On the left hand side of the page is the Folder Navigation pane

Browse to where you want to store your work and create a folder titled ProE_TRAINING To do this: Right click and choose New Folder Create a folder with your name. Right click again and set this as the Working Directory; All your subsequent work in this session will now be saved here.

2.0 Creating a new part 2.1 In the Windows toolbar across the top of the

screen left click on the File pull-down menu.

Left click New Part

Make sure that Part is selected as the Type

Give the part a name - in this case, “Pager”

Left click OK

Getting Started:



2.2 You should now see the Pro/ENGINEER graphics window.

2.3 Left click the Sketch tool on the Feature

toolbar at the Right-hand side of the screen. The sketch dialogue box should open.

The Plane collector box is highlighted in

yyyeeelll lllooowww. You now need to select a sketching plane.

2.4 Left click the Front datum plane in the graphics window. The datum plane should turn Red to show that it is selected.

The name appears in the Plane collector and the highlight moves to the Reference collector.

The Top datum plane appears as the default reference.

2.5 Left click Sketch to accept the default

sketch placement. The Front datum plane rotates to appear flat on the screen, and the Sketcher drawing tools appear on the Right-hand side of the toolbar.

3.0 Creating a sketch 3.1 Adding Centrelines

Before you draw, it is useful to add centrelines to you sketch. Centrelines are useful as they allow you to mirror shapes and to quickly place sketches.

On the Sketcher toolbar, Left-click the

Centreline tool from the Line fly out menu.

Let the cursor snap to the vertical axis line and Left-click the left mouse button. A

yyyeeelll lllooowww centreline appears, attached to the cursor.

Move the cursor to rotate the centreline to coincide with the axis line; Left-click to place it.

Middle-click to exit the tool.

Sketcher Setup



3.2 Left-click on the Rectangle sketching tool

and sketch a rectangle that is cantered on the centreline and rests on the Top datum plane.

The dimensions of this rectangle will be 50 (height) and 80 (width). We will edit the dimensions once the rectangle has been drawn.

You should see two opposing Red arrows appear when the rectangle is symmetrical about the centreline.

Left click to complete the rectangle and Middle Click to exit the tool.

3.2 Edit the dimensions to be 50 (height) and 80

(width) The sketch should now appear with grey (weak) dimensions displayed – (if you can’t see the dimensions left click on Select items)

3.3 Left click the tick in the Sketcher toolbar to complete the sketch.

4.0 Creating the extrusion

4.1 Left-click the Standard Orientation view from the Saved views fly out menu.

4.2 Left-click the Extrude tool from the Feature toolbar on the Right-hand side of the screen.

4.3 Set the height of the extrusion to be 12 in the Dashboard at the Bottom Left of the screen

4.4 Left click the Green tick at the Right-hand

side of the Dashboard to accept the extrusion.



5.0 Adding Rounded edges You will now use the Round tool to add round features to selected corners and edges of the model 5.1 Use the Middle mouse wheel to tumble the

model so that you can see two of the corners of the extrusion

5.2 Left click to select the Round tool and

Left click on one of the corners of the extrusion.

5.3 Hold down the Ctrl key to select the three

remaining edges - they should all turn Red to show they are selected

5.4 Set the radius to 5 in the Dashboard 5.5 Left click the Green tick at the Right-hand

side of the Dashboard to accept the round. 5.6 Do the same for the top edges to finish

rounding the edges of the extrusion

6.0 Pager buttons 6.1 On the Sketcher toolbar, Left-click the Datum Plane Tool

6.2 Left-click on the Top Face of the pager

extrusion Left-click OK in the

Datum Plane dialogue box to accept



6.3 Create a sketch on this new datum plane 6.4 Add a vertical Centreline as in 3.1 above 6.5 Add a Horizontal Centreline 15mm from the

bottom edge. To do this add a dimension picking up the bottom edge and the centre line suing the Dimension tool

6.6 Sketch the button shapes using the Line

and Circle tools. The Line fly-out menu has a tool to allow you to draw lines at a tangent to circles to help with this.

You can also use the Mirror tool from the Edit drop-down menu and the Trim fly-out menu has a Dynamic Trim tool which may be useful as well

The dimensions for the buttons are shown below: 6.7 Left click the tick in the Sketcher toolbar to

complete the sketch.

6.8 The Rename Sketch 2 in the Model Tree on the Left of the screen

6.9 With the sketch selected (the outlines should

be Red) Extrude the button shapes 3.0mm above and below the surface by selecting Extrude as a Solid, Extrude both sides and Remove material from the fly-out in the Dashboard

6.9.1 Left click the Green tick at the Right-hand

side of the Dashboard to accept the extrusion.



7.0 Shelling the pager casing 7.1 Use the Middle mouse wheel to tumble the

model so that you can see the underside of the extrusion

Select the face and Left-click the Shell tool from the Feature toolbar at the Right-hand side of the screen.

Change the thickness to 2.0mm change the thickness direction in the Dashboard

7.2 When you tumble the model you will notice

that we have lost the button holes on the top surface. To rectify this we need to pick the Shell function in the model tree and move it above the last Extrude 2

We then need to redefine the extrusion to make sure it goes through the surface of the casing. To do this Right-click on the extrusion and select Edit Definition


side of the Dashboard to accept the new height for the extrusion.

Save your work and leave it open on the screen Your model should now look like this:



8.0 Creating the Pager Base 8.1 Keep the file for the Pager open and create

a new file called Pager_Base (remember to use underscore)

8.2 In the Windows toolbar across the top of

the screen left click on the Window pull-down menu and select the file PAGER.PTR

8.3 Right-click on the sketch called BUTTONS

in the Folder Navigation pane and select SUPRESS from the fly-out options

8.4 Select Sketch 1, Extrude 1, Round 1 and

Round 2 by Left-clicking each file in turn and holding SHIFT down. Right-click to GROUP the files

8.5 The files selected will now appear as a

group as shown. Go to EDIT on the Windows toolbar across the top of the screen left click on COPY from the pull-down menu

8.6 Switch back to the Pager_Base file and use

EDIT – PASTE to insert the copied files. At this point you can scale the copied files if you wish. Accept the default settings and select the TOP Datum Plane and confirm the sketch

8.7 You will be prompted to ‘select references’

to position the drawing. Select the Vertical and Horizontal centrelines to confirm the sketch. Drag a window around the sketch and reposition it central to the centrelines. (You can then zoom in and adjust the dimensions to place it central to both centrelines as shown)

8.9 Left click the tick in the Sketcher toolbar to

complete the sketch. The new part you have created should appear as shown below. You now need to SHELL it as before to create the base for the pager

side of the Dashboard to accept the part. 9.5 Select the part and hold SHIFT down whilst

also holding down the SCROLL wheel and move the part to the side

9.7 Repeat the sequence this time selecting the

PAGER.PTR file. Before you confirm the new part select the two thin faces of the parts as shown to Mate them together. Make sure Mate is selected in the Dashboard

9.6 Select to reposition the parts central

in the Graphics Window 9.7 Tumble the model and use the Zoom tool to

select two edges before using Align to line them up. Repeat this process to line up both parts and Left click the Green tick at the Right-hand side of the Dashboard to accept the assembly.

Your assembly should look like the one shown below:

Extension Task 2 Create a screen and a set of buttons using the geometry from existing sketches and add them to the final assembly as shown

Extension Task 3 Use the TEXT tool to add a company name to the front of the pager as shown



10.0 Introduction to Rendering Pro/ENGINEER Wildfire 3.0 Schools Edition incorporates a range of very powerful rendering tools, which allow you to place your finished models into photorealistic environments. This includes a wide choice of realistic lighting, shadowing, and background ‘environments’. Photorealistic rendering in Pro/ENGINEER Wildfire 3.0 uses two rendering engines, PhotoRender and Photolux. The Photolux renderer has the more advanced capabilities but is more demanding in terms of computing capability. As a result rendering on older PCs may be quite slow. To access the Rendering tools: 10.1 In the Windows toolbar across the top of

the screen left click on the View pull-down menu and select Model Setup and Render Controls from the fly-out


the screen left click on the View pull-down menu and select the Realtime rendering option

10.3 Chose the ‘Assign colours and

appearances’ option from the Render Control to change the colour of the whole model or specific components

10.4 Use the Room Editor to alter the background

effects. Roll the wheels to position the Walls, Floor and Ceiling and scale then to suit

10.5 Once you have created the desired effects in

the room select File – Save As to save these setting for use with another model

10.6 Experiment further with the different effects

and settings to get a feel for the rendering capabilities of Pro/ENGINEER Wildfire 3.0 Schools Edition



11.0 Extension Tasks 11.1 Go back to the model you have created of

the Pager and add a battery compartment detail on the underside of the model


the screen left click on the Help pull-down menu and select the Help Centre to access the Tutorials. Have a go at the ‘Creating Cubes, Rods, Cones, and Spheres’ tutorial or ‘Cell Phone’ in the ‘Getting Started with Pro/ENGINEER’ tutorial
