When you import a converted drawing (native DWG, say) into Layout, you can find that elements are nested several layers deep. Unfortunately, Layout does not have the equivalent of Outliner that Sketchup has to help determine levels of nesting. Would it be an idea to have it?
I suspect many of us would like Layout to have more in common with the way Sketchup works. It just seems very odd to have two allied software packages that work so differently. I guess this will come if and when Layout is redesigned root and branch as is so desperately needed.
