XTrackCAD is a open-source, free, CAD program for designing model railroad layouts. You can easily create layout of any scale or size. Libraries for many brands, scales and gauges of track and turnouts/points and model structures are included. Adding new components is easy with the built-in editor. It runs on Windows, Mac and Linux,
ThanCad is a 2dimensional cad, with limited 3d support and raster inclusion capability and emphasis in engineering. It is being written in Python and since it uses the Tkinter library, it is platform independent.
Draw vector graphics to scale using a descriptive language
Drawj2d creates technical line drawings using a descriptive language. It writes pdf, svg, eps, emf and dxf vector graphics or png images. It runs on all platforms that run Java. It is inspired by Asymptote but with a tcl-like syntax and 2D only.
XDraft is a mechanical drawing editor similar to XFig or various Windoze cad programs, but geared towards more precise drawing. XDraft adds input constraints and other features that makes it highly suitable for power users. Also includes dimensioning.

...In the 70s-80s I was trying to do 3D on early computers - big BW pixels! By late 80s I saw ray tracing and had to write my own.
I wrote the 1st ver while taking vector calculus and CAD programming classes c. '92. I was intrigued not only by the beauty of the math but also ray tracing curved metals. This is actually the 2nd ver, ported from MFC to gnome (with enhancements like optional GL) c. '00 with some help from David.
