Well, to use Blender as it is for CAD seams to be a real adventure... entering 
accurate geometry, without snaps, is hard. And deriving plans from it... well, 
I am sure it is possible "somehow" ;-)

BRL Cad seams to be made for this kind of project on the firtst view. I think 
if the actaul design is done, you can perfectly model it in brl-cad. I am not 
sure if you can design in a reasonable way in this application.

I am currently investigating what is possible with brlcad and what is not, and 
I have to say that, while ok for modeling, a CAD without a functional GUI is 
hardly useable at the design phase. As long as I am assembling geometry 
(typical CSG stuff, e.g. putting some known cylinders together), I can easily 
do so without GUI. But now imagine that you have to attach a cylinder to the 
intersection of two existing ones. In most CAD, you will switch on a 
snap-cursor to intersections. In brl-cad, as far as I could understand, you 
will take out paper and calculator and start calculating the coordinates of 
that intersection point... Maybe I am wrong here, if so, it would be great to 
hear.

(The background: I planned to model a steel structure of a building consisting 
of both columns and beams formed as arcs...)

It is sad that Microstation's engagement in Linux was... well... limited.

So, from my point of view, there is no 3d-CAD for Linux I could advise anyone 
to use for professional work now. Maybe I am wrong.

CU Lars.
