This little file shows the dimscale problem, the text gap in leader excess, and how the diameter dimension wish might look. I noticed in this comparison that text wrap on the leader text is not carried through to V6.
The dim property overrides is working and is better thanks, I missed it first time round as my tired eyes didn't notice the expand arrow against the darkish background:
The various boxes in More Properties could use a bit of a stretch
I withdraw this wish Lowell, on testing a bit more it seems that the text remains constant width while the lines can be adjusted in the normal way - didn't notice this before..
Overall the annotation package is looking good - fewer clicks results in smoother work flow, thanks for that.
