George, Thanks for your suggestions. I am already using DesignCad and have considered doing just what you suggested — transfer the 3D model to the 2D program and then delete the extra lines. I was hoping there was a more "automatic" way of doing this, but maybe that was wishful thinking. Correct me if I am wrong, but I believe there may be another drawback to that solution: When a wireframe of a curved object is transferred to 2D, I don't know if there is necessarily a line generated which corresponds to the visible edge of the object. There may be lines very close to either the front of back of the "edge" but I don't think any of these represents the true edge. (Unless the "hide hidden lines" command generates an "edge" line — do you know if it does?) I think an alternative solution may be to export a rendered image to a drawing program such as Corel and to trace over to visible edges. May be very tedious, though. If I get around to trying it (I haven't learned Corel yet), I will let you know how it turns out. Thanks again for your help, Michael Katz
