Animating Constraints

If you decide to make one constraint vary, then the constrained sketched elements react. In other words, after assigning a set of values to the angular constraint the whole system is affected.

Before you begin: Sketch a piston and define one angle constraint.

About Animating Constraints
  1. Select an angle constraint.


  2. From the Analysis section of the action bar, click Animate Constraints .
    The Animate Constraint dialog box appears.
  3. In the Number of steps box, specify the number of instances to be visualized.
  4. In the First value box, specify the angle value for the first instance.
  5. In the Last value box, specify the angle value for the last instance.
  6. Select Hide constraints check box for hiding constraints.
  7. Select Loop to run the animation in a repeated loop.
  8. Select Run Animation to see how the sketch is affected by the different values assigned to the constraint. The command induces a clockwise rotation. These three pictures below give examples of this behavior.
