GPL-Licensed QCAD Ported to Mac OS X
AlwaysTimeForCoffee writes "QCad, a free open-source 2D CAD system for Linux, various Unices and Windows, from RibbonSoft, has been ported to a native OS X version by Gilbert Duivesteijn. A screenshot of the OS X version can be found here. Qcad is a light, GPL'd version of the commercial available CAM Expert. It truely is an outstanding program and has earned 5 out of 5 Penguins on Tucow's Linuxberg and IceWalker review. With this native OS X release, a commercial quality CAD system has been made available to the Apple community."
It is not native, it uses QT which uses custom widgets so it is slow, a native would use Cocoa (or maybe Carbon) libraries and almost no custom widgets.
Autodesk is considering porting Autocad if they receive sufficient indication of interest - it was a big enough deal to make Apple's news page. A Google search might turn something up. Here's what I could find:
