Am I the only one that seems to be getting random errors on a consistent basis? I currently am working on a conveyor design and ham constantly having to supress and unsuppress mates after a rebuild because for whatever reason, they are becoming over-defining or unsolvable. I am running SW2014 SP 2, but have noticed this in past versions too. It seems to happen with larger assemblies and is taking up about a half hour per day. Does anybody have any ideas as to why this is happening, or how it can be fixed/avoided?
