Assembly Constrains in new NX
Assembly Constrains in new NX
(OP)
Hi,
In earlier NX version we had mating constrains, which works in a way as FROM-TO approach while selecting the order of constrains.
FROM - Bolt center moves TO block center axis.
Now in new NX version, we have assembly constrain. It does not have any control over which component has to move around which component. This makes me to re-do my constraining steps till I get this correct.
Is there a easy approach in assembly constrains?
Thank you for answering.

RE: Assembly Constrains in new NX
The most predictable way that I've found is to start with the most significant component (chassis, main housing, base plate, etc) and make that component fixed (add a fixed constraint) then proceed to constrain the other components to it. The fixed component will remain stationary and the other components will move to it. With the older "mating constraints", the "fixed" constraint was frowned upon as it could cause problems later; however, this is not the case with the new assembly constraints.
