Tutorial 5: Revolves, Patterns, and Copies

Introduction

The Revolve option is useful for designing circular parts and features. Patterns and copies allow multiple instances of a feature tobe created with little effort. In this section, you will revolve a section around a centerline to create a pulley and a hole. You will alsocreate a pattern of holes and a copy of this pattern.

Creating a Revolved Part

1. Start Pro! "ildfire.#. $hoose %&ile' () %*ew' and name the new part %!+ample'.

3. Select the Revolve Tool icon from the tool bar at the right of the screen, as shown in &igure .1.

%&igure .1'

4. Select the S-etcher icon from the revolve tool bar on the dashboard.

5. Select the plane labeled &R*T and select the S-etch button in the Section menu.

6. Select %S-etch' () %Intent /anager' from the menu bar.

7. 0oom in so that you see the coordinates shown in &igure .#.

8. Select %ine' from the 2!/!TRY menu, and select %$enterline' from the I*! TYP! menu.

9. $lic- point 3 and point 4 shown in &igure .# to create a centerline.

10. Select %2eometry' from the I*! TYP! menu.

11. 5raw the section shown in &igure .# by clic-ing the endpoints with the left mouse button, and then clic-ing the middle mouse

button.

12. Select %Regenerate' from the S6!T$7!R menu.

13. 3dd the dimension shown at point 3 in &igure .8 by performing the following steps9

$lic- !dge1 with the left mouse button.

$lic- $enterline with the left mouse button.

$lic- !dge1 again with the left mouse button.

$lic- point 3 with the middle mouse button.

14. &ollow the same procedure to add the dimensions at points 4 and $. 15. &ollow the normal procedure for dimensioning to add the dimensions at points 5, !, &, 2, and 7.

16. Select %Regenerate'. You should now be able to see dimensions similar to those shown in &igure .8.

17. Select %Scale' from the /5 S6!T$7 menu.

18. Select the dimension at point 3.

19. Type : into the te+tbo+ and clic- the chec- mar-.

20. Select %Regenerate'. 3ll of the dimensions should scale.

21. Select %/od !ntity' from the /5 S6!T$7 menu.
