This question concerns constraining parts together in which one follows a path in another part, like an overhead garage door would follow in its track.
I can use a coincident connection between a point and a spline composed of various tangential elements in Animation. However, when applying this to Motion the Mate doesn't hold. It works with single elements (an arc or a line).
I'm asking this in case anyone sees anything simple that I am doing wrong.
Assembly file showing one part constrained at both ends by coincident mates between a point and
a spline of three tangential elements.
In one video attached, an animation successfully leaves the coincident mate attached.
In the second video, a Motion Analysis is performed resulting in the coincident mate failing.
In the past I have gotten around this by using Solid Contacts, but that seems like a very complex way to solve an issue. The assembly I have provided here is a tiny, simplified example of the work I am actually doing and adding Contacts everywhere in which a similar constraint is needed adds enormously to the solve time and overall complexity.
Thanks in advance.
