I have a part that I'm working on from a colleague. There are thickened surfaces, but when I go to modify the feature, the "Merge Result" is missing from the thicken command. I tried offsetting another surface on the same part and thickening it, but again, "Merge Result" is not in the command dialog.
So I restarted SW thinking it was a glitch. However, same thing. Also, I did create a basic part and tried the same thing on that. "Merge Result" is available to me on the other part.
If I create a boss in the part I'm having problems with, the "Merge Result" option is there.....
