How do I connect 2 objects "hardly"?
 

I'm doing a primitive car in Maya using dynamics. But I can't find the simplest "constraint" which is to connect 2 objects in a mode they don't move relatively! You can see the actual state of my test with this small divx5 avi.

There's a "Rigid Bodies and Constraints" tutorial in the online docs.

Thanks Kbrown:)

I forgot about that tut...
