Tutorial 1: Extrusions, Sketching, and Cuts

IntroductionExtrusions are one of the most basic ways to design a part in Pro/E, and sketc hing is an important part of t he design process. In this sect io

you will learn basic operations by creating a simple part using an extruded protrusion. You will then modify the part using a cutting operation

Starting Pro/ E and Creating new Part

1. Start Pro/E Wildfire.

2. Select [File] -> [New] from the menu bar. The dialog shown in Figure 1.1 will pop up.

[Figure 1.1]

3. Type the part name [Example1] in Text Box.

4. Click [OK] button (or press Enter Key). You will see the screen shown in Figure 1.2.

Sketching and Protrusion

1. Select the Extrude Tool icon from the tool bar at the right of the screen, as shown in Figure 1.2.

2. Select the Sketcher icon from the extrusion tool bar on the dashboard at the bottom of the screen.

3. Select the plane labeled FRONT. This will allow you to sketch in the xy plane and extrude in the z direct ion.

7. Select [Sketc h] -> [Intent Manager] from the menu bar. This will bring up the Menu Manager shown in Figure 1.6.

[Figure 1.6]

8. Now sketch the shape shown in Figure 1.7. Select [Line] from GEOMETRY menu of the Menu Manager.

9. Use the left mouse button to click points A, B, C, D, E, F and A shown in Figure 1.7. After clicking these points, press the mouse middl

10. Select [Regenerate] from SKETCHER menu of the Menu Manager.

11. Zoom in using the wheel on the mouse or by moving the mouse up and down while holding CTRL and middle mouse button.

12. Move the sketch to the center of the screen by moving the mouse while holding the middle mouse button and the Shift key.

13. Now set the size of the shape. Follow the steps below:

Select [Dimension] from SKETCHER menu.

Click Edge2 and Edge6 with the left mouse button, and then click point A with the middle mouse button.

Click Edge1 and Edge5 with the left mouse button, and then click point B with the middle mouse button.

Click Edge2 and Edge4 with the left mouse button, and then click point c with the middle mouse button.

Click Edge3 and Edge5 with the left mouse button, and then click point D with the middle mouse button.

15. Select [Modify] from SKETCHER menu.

16. Click the number that is circled by A shown in Figure 1.9. Then type the correct dimension underneath the toolbar. In this case, type

200 in the text box, and c lick the c heck button.

17. Similarly, change the number that is circled by B to 200, by C to 50, and by D to 50.

18. Select [Regenerate], and then Select [Done] from SKETCHER menu. Pro/E will exit Sketcher Mode.

19. Type in 100 into the extrusion depth box on the dashboard and click check button.

21. While there is no real undo option in Pro/E, the model tree can be used to modify features you have already created. Right click on thpart you wish to alter, and select [Edit Definition] from the list of options. You can then alter the part. This topic will be explored

further in Tutorial 4.

22. Select [File] -> [Save] from menu bar and click the c heck button at the bottom of the sc reen to save the part.

Crea ting Cuts

1. Select the Extrude Tool icon from the tool bar on the right of the screen, as in Step 1 of the previous section.

2. Select the Remove Material icon from the extrusion tool bar on the dashboard, as shown in Figure 1.12.

3. Select the Sketcher icon.

4. Locate the bottom face of the part by using View Manager as described in Step 21 of the previous section. Select [View] -> [View

Manager] from the menu bar, and then double click [Bottom] from the pop-up window. You should see the view shown in Figure 1.13

5. Click on the bottom face of the part near point A in Figure 1.13 to select it as the sketching plane.

6. Change the orientation to [Bottom] on the Section menu.

1. Click the Sketch button from the Sec tion menu. Pro/E will switch to Sketc h Mode.

2. Select [Sketch] -> [Intent Manager] from the menu bar.

3. Select [Line] from GEOMETRY menu.

4. Click points A, B and C shown in Figure 1.14 with the mouse left button, and then click the middle mouse button.
