Someone else brought this up in the 2004 group but didn't get an answer. There used to be a way to dimension an arc length. You could cycle between degrees and length by pressing space. Why this was changed, I don't know. There is a setting in the dimension style to have it do length or angle but that seems stupid as you would need to setup a dimension style for each. I found a key-in command that does exactly what I'm looking for but I haven't been able to find the button to do it. DIMENSION ARC SIZE
Anyone have an answer?
