I would really like to speed up my drafting by being able to trim one line to another. If I could pick it, I would have it function like the trim/extend tool in Revit. I would like to see it as a option click for the Split tool. Elegant!
I really like the scale drawing feature. It has improved my workflow greatly. I find myself using scrapbooks to greater effect than ever. Extend/Trim tool would be a huge step forward.
