Some ideas:

BRLCAD is always an option:
"BRL-CAD is a powerful solid modeling system developed by the U.S. Army
Research Laboratory (formerly known as the Ballistic Research
Laboratory, or BRL) that includes an interactive geometry editor (MGED),
a ray-tracing library with support for rendering and geometric analysis,
network distributed framebuffer support, an embedded scripting language,
image- and signal-processing tools, and a host of additional utilities.
The package supports a variety of geometric representations, including
traditional combinatorial solid geometry (CSG) primitives, solids made
from closed collections of uniform B-spline surfaces as well as
non-uniform rational B-spline (NURBS) surfaces, faceted geometry, and
n-manifold geometry (NMG)."

It is not FOSS, but Varicad is a 2D/3D CAD option for Linux. I believe
they have a 30 day trial version and discounts for students. This was
the most easily used software for Linux that I encountered.

There is also the CAE Linux Project, which I have used, but is much more
than just a "CAD" program. It is amazingly powerful software with the
GUI glue of many engineering tools written in Python / TCL / Tk. If you
are into CAE, look for the Salome-Meca-2007.1-GPL tarball.

I admit I find Blender confusing and difficult to use, as well as BRLCAD.

YMMV, HTH
