NX6 Default Assembly Constraint Tolerances
NX6 Default Assembly Constraint Tolerances
(OP)
I've been playing with NX6 assemblies and found that I couldn't get 2 components to mate properly. On investigation, I found that there is a tolerance for whether 2 lines are parallel, and another for whether 2 lines/entities are adjacent. Out of the box, the angular tolerance seems to be set to 1.733e-010 degrees, and the distance tolerance is set to 1e-5. Aren't these a bit tight? I backed off to a distance tolerance of 1e-3 and an angular tolerance of 1e-2 and things now work OK.

It's been my experience that NX's out-of-box tolerances actually the same as what you mention the default STEP tolerances are... you sure the really tight tol's you mention weren't actually custom-set?
