As a graphic legibility standard, our office avoids crossing callout leader lines through running dimensions, but at times this condition is unavoidable (Enlargement plans, Construction Details).
It would wonderful to have a checkmark option within the dimension's Object Info to allow a callout leader line to 'break' the dimension where it crosses, in order to retain graphic clarity in a drawing.
AutoCAD has this feature pretty well nailed down with their DIMBREAK command; it would be wonderful to have this simple upgrade as an option in VW.
