The specific challenge I have is setting up a filter in a repeat region BOM in Creo. When I try and set up a column definition I click in the cell and it opens a small window with a bunch of abbreviations. It sure would be nice to see a legend or glossary defining what these abbreviations are. The other thing is when you are setting up filters in a repeat region, it would also be nice to see a legend or glossary of the symbols and modifiers that can be used to write the filter commands. More than greater than, less than, equal to and not equal to. For example: what does # do? I found a # in a legacy filter on one of our old drawings and can't figure out what it does. Thinking I could go to your website and easily figure it out was a mistake on my part.
