I've been using Autodesk Inventor for some time now and have never came accross this problem, but recently in the assemblies the parts won't move freely. For instance I have these 3 parts mated together so that they move with eachother around an axis, and this has worked fine until now. I didn't see any problems in the constraints and I haven't changed any settings (as far as I know). Any help would be greatly appreciated as this has recently put a hold on a project I've been working on.
