Motion constaint

Question asked by Rick Wolfe on Jan 20, 2009

I have an assembly constrained to a 3-d spline with a coincident restraint.
There is a perpendicular plane restraint to keep it from swaying.
The problem is when I pull the assembly around the spline, occasionnally the
assembly will flip 180 degees. If I try to add another constraint, it warns me that the assembly is overconstrained. Any suggestions?
