    Mates Not Solving (Recurring Problem)

    Jeff Meszaros

      I have a fairly large model, and it seems every time I make a change to a sub-assembly and change the length of a part and go back to the main assembly there are mate errors. This is a little surprising when a coincedant mate is giving an error, but there are no other mates opposing it. At this point I rebuild the model, save it, rebuild again, but the error is still there. The only thing to fix this (short of deleting the mate) is to open up the mate, deselect 1 of the 2 faces used in the coincedant mate, reselect the same face I just deselected, and the mate solves itself (no more mate error).


      Some notes about my model (SW 2010 SP 5.0)

      The main assembly has four configurations, ~10 patterns, ~5 mirrors

      Most of the subassemblies have 3-4 configurations, sometimes the parts have configurations

      No external references used at all.


      This wouldn't bug me too much but this has happened in excess of 30 times in the last day and it gets frusterating running through the same process over and over again. This doesn't seem to be an issue with how I have built my model but rather how Solidworks is computing data.


      Anyone else run into this issue?

          Jeff, it would be a lot easier to assist you if you'd post the assembly with components.

              We've got the exact same problem with SW 2010 SP5.

              When I change a part in an assembly, I get a lot of errors on mates, which haven't anything to do with the changed part. Rebuilding doesn't do the trick, changing the orientation of the mate back and forth does the trick. Also reopening the assembly works, all the mates are suddenly solvable.


              I hope updating to SW2012 would sold the problem.

              If this is happening 30 times a day, then it seems like a good candidate for sending it in to your VAR to see if they can duplicate the problem. You may have to give them very explicit instructions on how to cause a failure. If you can get a repeatable failure, you may be able to do an Rx and send them the Rx file.It would be really great if we could hand SolidWorks some of these mate failures in such a clear way that they can finally get a handle on them. They've been struggling (at least I hope they have been struggling) for years now without much, if any, success.
