I've been tinkering with annotations and have gotten stumped on this one. I just want the insertion scale to be tied to dimscale. I havent found a way to get any drawing variables into the expression builder !dimscale doesnt work.
Anybody have any clues?

Next question would be what is the expression to get the annotation to rotate along a polyline that may/may not have arcs in it. I'm assuming that it uses a combo of the .bulge and .angle variables but I'm not sure, anybody done this before
