I hope I am hitting the right forum with this question...I have found that simple wall/ roof intersections clean up pretty nicely in section, but if things get even slightly more complicated, I get seams which I don't want to see. I don't know of a clever way to get rid of these lines, without exploding the imported drawing in plotmaker, which I am somewhat reluctant to do...I'd rather draw over the lines I don't want while in AC, just in 2D, but don't have a good workaround for hiding/ masking/ omitting lines that I don't want to see. Suggestions?
