Hi Katie,
Thanks for the reply.
I am on VW/RW 9.0.0. I did not check the black and white only option, but when importing the file, at the point where I am asked (when checking the point whether Colors shd be mapped to line weight) to chose a line weight, only colors black/white show up.
I am importing 3D objects.
The objects I download from 3dcafe.com, in this case I tried several cars. All of them just show up as black/white models when rendering. What version the dxf file is, I don't know.
I unstuff the .exe-files with stuffit expander, that does it, but maybe that's the problem, that the file doe not get converted properly...
