Assemblies - horizontal movement

frank_ring

For a realistic simulation I want to let the blue rolls glide horizontally over a virtual floor,
so that the comb-shaped plate can be moved up and down.
Which function has to be chosen here.

Thanks for your support.

Probably slider in that case. 

Have you experimented with all of the mate types and relations yet?

Here is a partial solution:  https://cad.onshape.com/documents/5354ccfcb67526b370efe15e/w/5cc6d0210cf7499d4efcd377/e/64d9e7204d736b44cbd166e0

Right click mate"Animate this" in Assembly 2 and view the coordinated motion that may be what you want.  It was necessary to add "Ground"  to provide a face for the tangent mate to interact with.  My attempts to further constrain the motion to simulate the real world more completely were unsuccessful.

I find this sort of animation to be one of the most challenging tasks in Onshape:  the feedback "mate overdefines the assembly" seldom points in a productive direction.  Trial and error is the last resort.

@edward_petrillo
just needs to set the link to shared or make it public is all.

Sorry i flubbed it- try the link https://cad.onshape.com/documents/5354ccfcb67526b370efe15e/w/5cc6d0210cf7499d4efcd377/e/64d9e7204d736b44cbd166e0

Very nice and instructive animation! 

The construction, as you can guess, only makes sense with a left and right hand trapezoidal thread spindle - the project is still "under construction".
