Archimedes CAD is described as 'Archimedes is a free and open source CAD (Computer Aided Design) software. It is a robust system built over Eclipse’s Rich Client Java Platform fully based on plug ins. This means it is easily extensible but also has a pretty thin core that allows you to select the features you' and is a CAD software in the photos & graphics category. There are more than 50 alternatives to Archimedes CAD for a variety of platforms, including Windows, Mac, Linux, Web-based and BSD apps. The best Archimedes CAD alternative is FreeCAD, which is both free and Open Source. Other great apps like Archimedes CAD are LibreCAD, Autodesk AutoCAD, SOLIDWORKS and BRL-CAD.
