There are a number of existing plugins that offer some CAD-like facilities,
and the situation is improving all the time. I recommend CADTools and
CADDigitize as being the most useful and usable for CAD-lite. Note that
CADTools is broken in QGIS 2.8, but works fine in 2.6 or 2.10. There is
also CADInput which was an experimental plugin up until 2.6 but was
integrated into the main QGIS in 2.8, this allows you to more directly
enter dimensions required but is not as user friendly I find. Not that this
is all 2D CAD, 3D is something QGIS doesn't do yet.

Longer term, CADInput will be better integrated, and the new geometry
engine in 2.10 will greatly improve things by having the z dimension
built-in thus making QGIS 3D capable. I know there are a lot of people
looking at how to bring QGIS up to standard for CAD and BIM uses

As for compatible CAD programs, I vaguely recall some work to make LibreCAD
work with QGIS, as they both use Qt as the toolkit? Not sure if anything
happened with that.
