I know some people enjoy this, but I personally HATE drafting 3d casters or pillow blocks. I know you don't usually have to draft in casters in 3d, but drafting pillow blocks in 3d is essential to automation designs. So, I just found this, and I have to try it out. I foresee 3d EVERYTHING for my theatre, including clamps on lights.
