8. Click and drag either the wheel or the wooden handle to see the
mechanism work. Note that the last shaft turns at a final ratio of 16:1
over the handle.

You can save the
animation of a
Driven constraint
to an AVI or WMV
file by clicking the
Record button in the
dialog box.

9. Locate the Drive This Constraint item in the Browser under the New
Shaft part.
Even though this constraint is suppressed, it can still be used to
animate the assembly.

10. Right-click the constraint, and select the Drive Constraint tool from
the context menu.

11. In the Drive Constraint dialog box, set the End value for the range of
motion to 360.

12. Expand the dialog box, and set the value for Repetitions to 3 as shown
in Figure 8.23.

13. Click the Forward button to see how the mechanism works.

Applying motion constraints to an assembly helps you verify that your design
works the way you need it to work. Being able to animate this action can help
you show others what you intend the design to do.
