extract 2D wireframe linework off a 3D model
I have a 3D model of a highly non-rectilinnear building, but I also want to make traditional 2D elevations/sections - which are arduous to constreuct for such a building, requiring much 3D trigonometry to determine offsets and angles as projected to the elevation plane. The 3D model has solved all that. So is there any way, having oriented the model to the desired elevation plane, of capturing the visible edges of the solids as 2D wireframe lines, true to scale, drawn in the 2D xy elevation plane in modelspace, which can be incorporated into the elevation drawing, ready for embelishment?
That is, a bit more automated than simply tracing over the model's edges?
