nanoCAD is computer aided design software of a high calibre with a low barrier to entry. Completely free to use and suitable for any level of 2D CAD work.
A Great Alternative
nanoCAD allows you to be able to draw any number of technical drawings for a variety of purposes, such as engineering diagrams, and vector-based art, such as would be used with a CNC etching machine. The interface is very similar to that of popular CAD software, AutoCAD, meaning people familiar with that software should feel at home using nanoCAD.

As far as CAD applications go, nanoCAD is not the best of the bunch by a long way. However it is one of a very small number that is free. So if you can overlook the lacking features when compared to AutoCAD. You will need to register for the free version, and a paid upgrade to a more feature rich version is also a possibility.
