I have the same problem when I am modelling a building in AutoCAD it is nearly impossible to keep track of drawing counterclockwise, I even gave up thinking about it it is to time consuming. If their is a program however within AutoCAD where you can select a bunch of faces after you have drawn them and then change their normals automaticaly facing one way it would be great, or something that does the same thing in 3Dstudio, flipping face by face for a building gets on my nerves, so I choose for longer rendering times (2sided). Is their a demo available for your product, I'm in europe I am interested. I'd love to see it.
