Dynamic Block Creation (Distance Multiplier)

Take step shaft as an example, if we stretch the left part of the step shaft and the keyway still is at the center point of smaller diameter shaft after stretching. As the following picture shows:

1. Add Linear Parameter and Stretch Action for Step Shaft:

2. Add Move Action for keyway:

.

3. Modify Distance Multiplier of Action:

Select Move Action and modify the default value from 1 to 0.5 in the property of distance multiplier, save an exit block editor.

4. Test Dynamic Block:

Although Stretch and Move have a common parameter, but when Distance Multiplier of Move is modified as 0.5, the displacement of Move can only stretch 0.5 times of displacement.
