I'm stumped on this one. I have two components that I am trying to place two mates on. I want a coincident mate with two axes, and a coincident mate of two planes. When it tries to mate the two planes it throws the error that the coincident mate cannot be satisfied because the planes are not coincident, and specifies the distance between them. Of course they aren't coincident... that's the point of adding the mate.

Other posts have stated that it can be because a plane isn't actually 90 degrees, but 90.000012 degrees. The image below is after using the measure tool on both planes. It states that the planes are indeed parallel.

If I suppress the mate of the axes before it and then unsuppress the same mate, all errors go away. This is not an acceptable solution as the assembly is being built programmatically. Attempting to try and just rebuild the assembly 4 or 5 times to try and get it to "snap together" does not resolve the error either.

Has anyone had this issue, have any ideas, etc? Any input is appreciated.
