Re: Multi-level assemblies with motion
Thanks everyone. Turning parts to "flexible" did the trick. I'm not a big fan of demoting assembly parts into sub assemblies. I prefer the Bottom-Up approach to assemblies because the same parts/sub assemblies occassionally get used in several locations around the robot.
That being said, I've found the Top-Down approach for part modeling really helps if you're constructing an assembly, because as Nemo said, you want to constrain to axes and planes for better stability.
