I need to find a way to have an object move linearly while I turn another object

chris — Fri, 12 Nov 2021 20:37:04 GMT

I'm trying to work out how to have a landing gear foot lower while I turn a handle. I'm not sure how in "Parameters or iLogic" how to tell one part to move linearly while another object rotates. simply put, I need a way to map something like this:

For every deg of rotation of part "a" I need part "B" to move "X" distance?

Use the motion constraint:

I'm trying to make this work in "real time" as I drag a slider back and forth in a Form

I think I found your workaround (although it would have been better to operate on your 3D models to make sure it worked there). See my screencast to check it out: https://autode.sk/30fIuAE

You can apply a combination of Tangent constraint and Rotation/Translation, and even remove the visibility of the "gear" part to make it seamless (Part3, inside my assembly sample attached also here to this reply):
