We are having tremendous difficulties with our assemblies that have configured parts and subassemblies. We open up assembly files that we know had the right configuration of a part(s) and in one or more of the assembly configurations the parts change to (what appears to be) the first instance's configuration of the part. haven't found a work around, and it is eating us alive.
We have produced check print drawings that show all the right parts, the check print gets approved and when the drafter goes to final plot, things like all the nuts change to be .25 or all the snap rings change from say a 2" on a 2" pin to a 5.5" on a 2" pin.
Shame on me because I though I had heard of something like this in the early SP's so I held off until SP3.0 when I thought I had heard configs were now good. We changed a few weeks ago and boom, it has been a productivity killer. No work around!
IMHO SW2003 has been the worst release since we started on 98+!
