Have a bit of a puzzle.  Was doing some ordinate dimensioning and a message flashed up for half a second, "Identical dimensions cannot be created in same ordinate group." LOL took forever to read the whole thing.  That was the first time I had clicked there.  I can do a baseline (upper in picture) or just plain dimension (lower in picture) but can't ordinate to these two spots. Not unsurmountable problem but just puzzling.
