Slow performance when regenerating instances

Slow performance when regenerating instances

Slow performance when regenerating instances

(OP)
I am currently modeling a heatsink (pin array, ~1500 .040 pins) using a combination of rectancular and circular arrays.  The problem I am facing is that it takes 10 min to regenerate my part when I change something.  

Is there a way to speed up the regeneration process?  Or only have UG regenerate parts that changed instead of the whole part?

NX?

If you're using NX-5 you might do better with instanced features than arrays.

RE: Slow performance when regenerating instances

Sorry for leaving out a few details:
NX Version: NX4
Command I am using: Insert==>Associative copy==>instance==>circular array

Is there a better way to make a pattern?

RE: Slow performance when regenerating instances

If all of the faces and edges of all of the new features will be identical (like when creating a bolt-circle in flat constant thickness plate, try using the 'Identical' Method as they will be created and will update faster.  If for some reason the system won't allow that option to work, try 'Simple'.  It not as fast as 'Identical' but it's better than 'General'.

RE: Slow performance when regenerating instances

Large patterns of repetitive details are always slow to some degree. It may be a question of the lesser of two evils. Avoiding muliple booleans is one way to address these issues.

Perhaps using Pattern Face in NX-4 may be more efficient than a feature array. You still find yourself creating rows and circular patterns but the whole system seems to be quicker and neater in the feature tree.
