Thanks for the info, Tweakie. I have downloaded and played with it a small bit. It seems to be a very good cad program, especially for the price. I found no mention of any kind of usage restrictions, such as commercial purposes or whatever, so that's great also! One thing I did notice, is that I could not save as DWG, and then import into vcarve pro demo. The options for 123d are extremely limited, it appears. Maybe that's just because its beta. Anyhow, great find, and thanks for sharing. I'm definitely going to work with it some more.
