Okay, it is time for me to go to bed -- but this is a lot of fun! This is a *very* unfinished 3D model of my CarBEN EV concept design. I did 15 section in DataCAD, and used the Ruled Surface tool on as many of them as would "behave" -- it did about 2/3 of all these polygons. And then I had to use the Pencil tool in ...SketchUp to form the rest of them... whew!
