Don't know which release this was initiated in - I jumped from R14 to 2004, but in the latter you can take a linear dimension* between two entities, then move one of them and the dimension updates! Cool, but just one tiny step away from being useful!! If only you could change the dimension to modify the geometry - Soooo close, yet so far.
