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.
I have tried the process of using Mass object to reduce the blackness of the lines further away from the elevations view point, and that mass element in view category is selected to be halftone. By choosing it to be halftone you can use this method to work on Elevations and Sections, while also annotated. (as opposite to what you suggested in the first post).
But yes, Autodesk has to come up with a simple solution for this.
