Maybe newer SW can do this (newer than 2001Plus) but for some reason I doubt it.
I want the ability to change any dimension to a negative number (or even zero, for that matter).
Why is this useful? In my part I have a rectangular cut with a centerline that is dimensioned to a plane in the middle of the part. If I want to slide the cut to the other side of the center plane I have to edit the sketch rather than just setting the dimension to -3. Likewise if I need to locate the cut in the center I again have to edit the sketch.
Yes, I could change the dimensioning scheme to reference one of the outside edges rather than the center plane but then I may have to sacrifice other things (like design intent).
It just seems like it should be such a simple thing to add this.
Or maybe my ProE background has twisted me.
