Quirky - that is what I am talking about

[lbuttery]

I'm not an architect nor can I draw at all

I think the benefit of doing a model first is that when the client says
move that window over there etc
a handdrawn elevaton needs to be re-done

even a 2D cad drawing would need some re-work
where the 3D model is just a few clicks

the 3D model also allows for additional views to be done from various
angles where the 2D drawing again would have to be created fresh
possibly from scratch

since I can't draw a straight line I have to use the 3D modeling method
