Adding Constraints to Linear Slides
Hello!
I'm trying to model working drawer slides for the lift on our robot. I've downloaded this part: McMaster-Carr. Unfortunately, after I import it it doesn't move at all. It appears to be a static assembly and I don't know how to add constraints to that. I've also tried deleting different segments of it so that I have separate parts, and then re-assembling them with slider constraints, but they still don't move. I was wondering if anyone had any insight into this? Thank you so much!
