I'm getting a no solution found error, but there's nothing wrong in the assembly tree.  It gives rebuild errors when used in a bigger assembly which causes the whole assembly rebuild time to be excruciatingly long - 30-45 seconds instead of 2 or 3 seconds.  I really don't want to have to remodel this assembly-I'd have to re do all the design tables, configurations, and lots of FEA setup.  Is there a way to fix this bug?
