Like using the “Enable on screen numeric input on entity creation” when you are sketching in SOLIDWORKS 2009 ??
BUT, have trouble being overdefined a lot because of this ??
Especially when “closing up” a profile ??
As you are sketching, just hold down the ALT key before you click to end a line and it will NOT add a dimension to that line (or arc, or circle, etc.)
Pretty cool !
