SYMPTOM/PROBLEM
---------------
When converting Mating conditions to Assembly Constraints, how does NX decide which components are given a 'Fix' constraint?

SOLUTION/WORKAROUND
-------------------
Mating Conditions are one-directional: component A is constrained to component B. So the mating condition will never move component B, whatever happens.
Assembly Constraints are two-directional: components A and B are constrained together, and when the constraint solves, either constraint can be moved by it.

Therefore, when a mating condition is converted to assembly constraints,
component B is given a Fix constraint (if it was not mated itself). This gives
the best representation of the pre-conversion behavior with the new
constraints.

The user can always delete the Fix constraints if they are unwanted. However, this will mean that the assembly has update behavior less similar to the unconverted behavior than before.

Grazie, questa non la sapevo. Ho verificato con un assieme fatto bene in NX5 svincolando dei componenti e il risultato è stato ottimo. La risposta del GTAC, a cui mi ero rivolto per un cliente che è passato da NX4 a NX7.5, mi ha fuorviato. Probabilmente gli assiemi di questo cliente erano in partenza fatti male.
