...of expensive Windows-based CAD, bricscad has just released another beta of their CAD software that runs on Linux. Bricscad is based on Intellicad, which means it's an AutoCAD clone that reads and writes .DWG files. The previous Linux beta had horribly slow performance on redraws and regens, but this has been addressed in the current beta. AFAIK, when they finally release it for sale, it should go for around $325 - $450, based on the prices of the current Windows offerings.
There's also another company, in Italy (ProgeSoft) working on a Linux CAD program based on Intellicad.
Wonder if anybody at Autodesk pays attention to these developments?
