Is it possible to limit motion of a link when it clashes with another link?

I am trying to model links with revolute joint, I would like to know if I can somehow limit the motion of a link with respect to another link when they clash.

Have you taken a look at this?

Yes, I did find this article. But I am trying to do the same using model which was imported from CAD. Any ideas how to proceed?

[Sebastian Castro]

That's a little tougher. All the contact forces require that you know the dimensions of the parts you imported from CAD.

If your parts are fairly simple and you can roughly estimate a sphere/block/etc. from them, then you could use that library from the File Exchange.

Otherwise, you may need to poke through the .STL and .XML files generated by SimMechanics Link to get the locations of the polygons. That would require you to create a more elaborate contact model from scratch, basically.

Thanks a lot. I was afraid of it. I'll try with simpler models first.
