Ten years ago I was a student at Georgia Tech and a co-op at Kimberly-Clark corporation. K-C used Professional CADAM at the time on IBM RS/6000 workstations. I became pretty adept with ProCADAM one quarter when I completely re-documented a paper mill in Tennessee. :) At the time I thought CADAM was light-years ahead of AutoCAD due to its longer gestation period (CADAM descends from 1960s technology at Lockheed) and its special-purpose funtion keybox. AutoCAD always required (requires?) too much typing. I discovered CADAM is now owned by the French company Dassault Systems (http://www.cadam.com/). To my (happy) surprise the downloadable Windows build of V5R11 CADAM works pretty well under Wine. My system: Red Hat 9 with updates. Nothing special except the nVidia drivers for my nForce 2 motherboard. I don't have the CADAM keybox (https://estore.cadam.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=TCS&Product_Code=CDK&Category_Code=H), which really makes CADAM fly. Now, if I could only remember how to erase something I drew previously... :) Jeff
