Hey all.
Our CAD specialist is having trouble in Solidworks that is really slowing our project down. He's doing his best to make a basic motion study so he can calculate the trajectory of our ball without having to adjust our actual prototype. But, to pinpoint his problem, "I can't get the pistons to move."
Can anyone post either a written or video tutorial on how to run a motion study with pistons?
(We download our pistons from Bimba.com)
Thanks a lot, this is exceedingly frustrating.
