User was working with an older part, which has evolved via "save as". Since this this parts creation, we have added new attributes, and expressions tied to those attributes, in our model seed file. Since the user wanted these, along with some other data from another part, they imported that other, newer, part file.
Now they have the data, and all the over lapping expressions, named p18'0, etc., as I expected. going thru these, trying to clean out the ones that are not needed, some of the expressions that were tied to other expressions, and attributes won't delete, even though we *think* we deleted its 'use'.
Is there an easy way to see where the expression is used? I thought there used to be a column for that in the expression editor, but I do not see it now. I swear I've seen "used by _______", some where in there.
