[Radiance-general] mkillum with 400 sources?

Hi,

yes, I guess for most this is ok. But if you have polygonal surfaces 
(which means that there may be more than 4 vertices), 3dfaces cannot 
represent these any more without first splitting them to triangular or 
quadrangular faces, if I understood the dxf-faces right. Am I wrong 
here? And triangular faces are the worst to use for mkillum.

Closed polylines might work, but as you can see from Schorsch's mail, 
there is again a difference between 2d and 3d polylines. And here, if 
you are not working with Autocad, it is really difficult to find out 
what kind of polylines are written to your dxf...

CU Lars.
