I am making an assembly of a machine. On this machine there are some safety guard, which i want to rotate to see if anything collides, BUT........... some of the mates "freeze" (I have no better word for it). And the only "cure" i can find, is to delete the mates (I have fully defined parts in this assembly, using only one mate), and make some new ones, which makes it work fine for a periode of time (15-30min.). And i can start all over. Any ideas?
I use the 2009 version!
