[Radiance-general] Preparing an open DXF file for import

[Lars O. Grobe]

Hi!

If you want a direct export without the 3ds workaround, Schorsch has a 
dxf2rad that allows that as part of his commercial products.

If you go 3ds, which will break all your surfaces into triangles, it is 
possible to use Blender to do some "healing" on the mess. I usually 
export the 3ds by layername, so that all objects (triangles then) from 
one layer become one object. In Blender, I only have to select one by 
one (but the number of objects is limited to the number of layers, so 
that is fine) and de-triangulate the surfaces of the objects. Finally I 
export the whole model as OBJ - which is supported in Radiance almost as 
well as the native scene language ;-)

Cheers, Lars.
