Are we able to edit the text in the suffix pulldown and add more common ones to it?
I think answer is NO, at least in NX 10.
There is no way so that the existing suffix values can be edited or new value can be added to the list. As manual text can be entered and used as a suffix. Why do you want to edit the values that are already available?
Are you looking for something like shown in the image. If yes then please refer the "Using control characters to format text".
I am adding hole tables and the summary rows that get filled out are not very decriptive. I can add a suffix like (6mm dowel) or (M16 SHCS) after the row of text to make it wasy to identify the holes. I was hopping to add the ones I use commonly to the drop down. I have approx 400 details each with multiple holes, just hopong to save some typing
I checked with development and they confirmed that the menu is hard-coded. You will not be able to edit it, or add to it. Please consider opening an IR with GTAC to submit a new Enhancement Request.
