Physically grabbing an object? Constraints?

Hello!

I have a machine pulling a piece of wire a little bit at a time by way of an animated grip that moves into position, grips down, then moves forward say six inches. I want to have the wire be 'grabbed' by the grip and move along the correct distance, be released, then grabbed again repeating the action.

I have tried animating both a parent constraint's strength parameter and enable on/off and while it works for the first grip and move, it snaps the wire back to the original position and does not move it incrementally forward.

Any ideas on how to easily animate an object being grabbed and released so the grabbed object continues to move forward in space? There's probably some easy constraint option I am overlooking.

Thank you,

Ryan

Howdy,

Are you setting keys for the grabbed object, too?

You may be interested in the CD Space Switch constraint in my CD Constraints plugin:

... which is specifically designed for that kind of task.

Adios,
Cactus Dan

Brilliant! That video helped immensely! I was not setting keys for the moved object. Working great now, thank you!!!
