NEWBIE: Arches, Barrels & Radius Furr Downs in Q&A Posted September 3, 2015 Hi David. Agreed, I do not expect perfection. This will more than suffice for representative 3D marketing views. For construction drawings, I will do as always - by provide elevations that specify all relevant reference points and details. This I can do in AutoCAD for the time being. This is simply a workaround until I can afford the real deal. Hey, I'm an old dog learning new tricks. I studied architecture back in the dark ages... before PC's. I remember when AutoCAD was the new trick.
