Had an idea this weekend about replacing the Text in a Dimension string.
I understand and agree with the philosophy that a Dimension MUST be trusted.
No DeadCAD-like "Its says 6'-4, but it's really 5'-3"
How about letting us overwrite the text as long as the replacement text CANNOT be converted to a Length.
That way, we could put things like "Verify in Field", "Not To Scale", or "See Mechanical", but we wouldn't be able to lie with a phony dimension. Revit is brilliant about converting Lengths typed in just about any possible way, so we should be able to rely on what we see.
I suppose someone could go and type in "Five foot three and a half", but it would be pretty obvious that you were lying.
