Hello all. 

In the picture above you will see a PCB board I am wanting to animate it sliding into the enclosure.  Thus simulating someone installing the board.  Line C and Vertex A are mated to each other in a path mate.  Line D and Vertex B are mated together in a path mate as well.  When going into a motion analysis it says that the mate cannot be free.  So I set it to a percentage of the path.  But it will not let me do it to the other path at the same time.  So when I try to animate it with a motor in motion analysis I can get it to work correctly.  Does anyone have experience making a motion analysis with two path mates?  Or does anyone have a better way to accomplish this.  Thanks in advance.
