Problems with CAD/dxf Import

Thank you Thomas,

i understand your suggestions and the procedure worked for an .dxf file i grabbed from the internet. It was a luminaire file from ERCO Lighting. I defined different layers and named them. The dxf2rad worked fine and i ended up with my desired modifiers.
But the files i got from this company didn't work! I opened them in Autocad 2005 and it said something that they were created with 'Pro Lignum 3D'. I can work with the file in Autocad but when i save it as .dxf then the dxf2rad converter messes it up. I get an empty file like that:
## Radiance geometry file "Video_Monitor.rad"
## Converted by dxf2rad 0.9: Sun Feb 05 18:33:59 2006
## C:\cygwin\opt\ray\bin\dxf2rad.exe Video_Monitor.dxf Video_Monitor.rad

## End of Radiance geometry file "Video_Monitor.rad"

I have no web space to post this .dwg file to and i guess to send the file to this list is a bad idea. Maybe i can send it to you and you can open it and see whats wrong. I have to ask this company if i can give these files away but maybe we can make a deal. :wink:
Thank you so far!

I had a quick look at the ProLignum product description and it
seems to be a highly parametrical software. To store this type of
information in a DXF file you have to use other data types than
simple geometry primitives. Unfortunately you can store information
in a DXF file that not every DXF reader (or even an older AutoCAD
version) can understand. I believe ProLignum makes heavy use of
that and dxf2rad can't find anything it could use.

You should ask the producer (http://www.kiwisoft.de/) about the
best way to get polygon data from their files. They may have a
converter or can tell you what to do in AutoCAD about this problem.

Hold it! I don't even have a version of AutoCAD around. I only
have IntelliCad on my system which does not work with ARX
applications (ProLignum is one). So I may not even be able to
open your files.
