[Radiance-general] mkillum with 400 sources?

Hi Schorsch,

thank you for the hint, for someone not that familiar in Autocadland 
this is really hard... especially as I am currently working in formZ 
and have to get the geometry (dxf) from there.

I did it a bit different now. I read again the obj2rad manpage, and 
found out that the obj geometry is triangulated ONLY if not planar OR 
if there is surface normal information included in the file. So I 
switched off the normals - et voilà, I got the polygons!

I have just started the next run of mkillum now, which is much more 
promising, cause there is really nothing worse to feed to mkillum than 
triangulated faces. I hope the normals will still be right, as the 
faces were editet correctly, but you never know what cad / modelling 
software is doing to your scene...

So thank You, and sorry for some of my questions which were a bit 
misleading cause the problem was completely different than I had 
guessed, but I am just getting crazy with that mkillum step in my scene 
at the moment ;-)

CU, greetings to Munich, Lars.
