I'll check to see if your on.
is this the address you want to be listed under? let me know.
they've been having some hardware problems. They had an electrical storm
that fried their system awhile back.

I've wondered about that, but Surya, atleast, has been trying really hard to
understand this Linux thing. I have not given up on them yet, but i'm not
ignoring other projects either.

I've been running a few ideas around, but have not had the time to do much
more than that. one thing i would like to see is somthing like Catia's
auxview2 function for an autocad compatable program. it "renders" a 3D model
to 2D vector entities(arcs, lines, conics,,, )I think this would solve some
of the problems people seem to have with paperspace. this would make
detailing a little easier(ie hidden line/dashed lines).

I might be able to help here, make me a list of functions and the format/size
you want them in.

no but i'll start asking. have you asked this from the qcad people?
they might be able to help.

my wife gets gealous anytime she sees me looking at a penguin or mouse.
