Moment of Inspiration 3D CAD Modeling

At http://moi3d.com you can download a free beta version of an upcoming 3D CAD modeling application, by a former Rhino programmer. It has a very pleasing, almost artistic interface and seems to work fine. The software is a beta-version, with an expiration date, but it will be able to save the files you create in the OpenNURBS format.

It has been called "SketchUp for MCAD" in the upFront.eZine newsletter.
