Hello everyone,

This is my first post on the SolidWorks board. I have some issues with moving several identical parts along a path at reoccuring intervals. Sometimes it works, sometimes it doesn't.

By adding constraints to the path mate, I get it to work when I drag the items but not when I animate them with a path mate motor, it either crashes or ends the simulation early. Although sometimes it does work, this is what I find even stranger.

I am using Motion Analysis as I believe it is only possible to add such a path mate motor in that type of study and I am not using gravity nor collision. Just mates that ought to work since the parts move fine by dragging. So I do not understand why it is stopping the simulation or crashing solidworks.

Can anyone please help me? I am desperate I've tried creating simple designs and I still get the same problem.

PS: Parts also are jumping to different locations when I edit something (a random object, light, or other things) and I do not have AutoKey turned on (which shouldn't be an option in Motion Analysis anyway, right?). I can send you the file by e-mail using Sprend if you want to have a look! I really need to figure out what is wrong. It is driving me nuts, been in this loop for 3 days now nearly 15 hours a day!

PS2: I am also 99% sure that I do not have any mates that should be affecting these parts in such a way, they should be constrained and behave like when I drag them.

Thank you in advance!!!!
