View Bounds and Disassociated Dimensions

[ROK99]

We just went to NX 9 from 7.5

A number of our drawings have special views that have dimensions derived from other views (in special cases). In 7.5, we were able to shrink the parent view boundary down because that view was large and unnecessary.

Now, in NX 9, when we shrink the boundary down, all the dimensions become un-associated in the child views. I understand this is not a best practice, but has worked for years on certain drawings we have.

Thoughts?

Since nobody has replied, maybe it would help if you tried explaining it differently. Myself, I dont know what you mean by dimensions derived from the parent view. Would you be meaning for ordinate dimensions and you have the origin in the parent view and the dimensions in the child view?

I for one am very interested in this issue as we will be moving to NX9 in January.

When we have to dimension back to a centerline that is so far away, we would do one of two things:

1. Make the bounds really big, build your dimension, and then shrink bounds back to your little area. Dimensions have only one extention, one arrow, and say "To Centerline."

2. Start your dimenstion, do an "Expand" to go inside and find the second object, and then "Expand" again to get out. This gave you access to something far away for a true dimension, but you did not see how far away it was (because it was inside the "expand"). you ended up with a nice big detail view.

This has generally worked. Now, if your dimension is linked to somehting that is not shown, it disassoicates.

That sounds like a bug (if it worked in NX 7.5 but now fails in NX 9.0 using the exact same model/drawing) and should be reported to GTAC.

Are the dimensions that get disassociated linked to that centerline ?

I have done the same thing as the OP before. This was in NX6 and it usually worked fine but sometimes not. I could never find out what the problem was when it didn't, so I just put a dimension completely in the manual boundary view, edited the dimension text, and turned off the leader and arrow on one side. Voila! I know, wrong thing to do, but it got the job done.

I haven't had the occasion to have to use the same kind of dimension in my new job using NX9, but it wouldn't work here anyways because we have a rule in Checkmate to find edited dimensions.

This actually sounds like a situation where the "double-arrow" dimension that John Baker posted in an NX10 video would work well.

UPDATE:
We recently went to NX 9, and 2 users showed me the problem that was the source of this thread. SO I posted the question here.

Upon further investigation, it appears this problem is related to just the 2 specific drawings, and not necessarily NX 9. We keep building new drawings in NX 9, and not having the aforementioned problem at all. It appears the issue is either part-specific, or because the file was created many versions ago (which NX 9 does get a little quirky with). We are still trying to pinpoint the problem with these 2 drawings.

But thanks to all for advice and suggestions.
