Working in a robotics lab, I often model assemblies that have links in series, with various degrees of freedom between the links. And when I have to make illustrations for a presentation to a client, I need to position the links in various poses. This can be just about impossible.
I get errors on mates that I know are not in conflict. When I suppress one of the mates and try to drag the components into position, I can get them close. But SW refuses to reapply the last mate when I unsuppress it. It tells me some BS like "This mate cannot be solved. Cylinders are out of alignment by 2.34533534 degrees." Or I can't drag a component at all, even though it's underconstrained!
What is this crap? Is there any way around it? There is nothing wrong with what I'm trying to do, but damn SW can't cope withit! I am so sick of the shortcomings in this software.
