Dynamic Block Creation (Chain Action)

If you want to realize symmetric stretch keeping keyway center no change and the length of smaller diameter shaft changes with stretch at same time, how will realize that?

1. Add Stretch for Step Shaft:

Because the follow-up operation will not stretch step shaft by grips of this linear parameter, the grip’s number of linear parameter can be modified as “0”.

2. Add Linear Parameter for Keyways:

3. Add Stretch Rightwards Action for Keyway

4. Realize Chain Action:

Add Stretch Leftwards action for keyway as the following picture shows. Special Notes: Do elect “Distance” to linear parameter to stretch leftwards operation objects set. This is a necessary procedure of chain operation.

5. Test Dynamic Block:

The realization of chain action has two important procedures: First, modify the property value of the parameter that need to happen linkage and modify the property of “chain action” from “NO” to “YES”. Second, select the parameter of objects that selected to linkage action to set.
