In NX 8 in some files after some use I can no longer link attributes to expressions. If I create a new attribute, then go to expressions and click reference part attribute I get the following error pictured below. Is there anyway to fix this. If I open the file in NX9 or 10 the problem is fixed, but unfortunately I can only use 8.
Are you certain that an expression linking to the attribute doesn't already exist?
yes, same file opened up in a newer realease solves the issue. I assumed siemens knew about this since this is not an issue with newer realeases, but perhaps not.
