Ah yes, that makes sense of course. But then for roofs and possible other parts that spread and turn you could use the LW command and change line weight for those specific lines, right?
Might be as time consuming as the masses, but I just dont like the idea of having to add new elements, and hide/show different masses for different views to get the desired result.
Well, yes, you could use the Linework tool, but that will take a lot more time than introducing some glass panels or masses. It's not ideal, but unless there is some specific tool for this, I think those methods are a good solution in the meantime.
