I posted recently about some quirks with leaders (they mostly work except for certain instances). AutoCAD imports are generally pretty good, but a few things are iffy (like the leaders and blocks… and especially text). If it gets better it would open up lots of opportunity. I’m struggling to adjust to Rhino’s annotations a little bit. They’re good but I’ve used ACAD’s for so many years… If text imported better (with subscript, superscript, fractions, etc…) that would really break down a few walls.
Rhino Exports so well into AutoCAD that I was planning to simply do my annotating in ACAD and then import back into Rhino.
