Been a few release since I used Creo last.
I don't remember having to hold control when picking entities for dimensions. You could, but it wasn't mandatory.
Am I mistaken?
Sometime back, maybe Pro/e Wildfire 5, they added the "extra" ctrl key. It was supposed to make it consistent with "windows" type programs.
We are just now going to Creo 4... and this is new.
It wasn't required in Creo 2.0
I wonder if there is a setting I can change to put it back the old way...
