[GRASS-user] dxf into 3d model

Hi all,
I want to import a dxf file like a house from google sketch up into a 3d model in GRASS nviz.
The 3d model is composed of a digital orthophoto and a digital surface model.
The dxf file doesn´t have any geoinformations and I can´t copy any geoinformations to it with the "v.proj" function.
Is there a tutorial how to put dxf files into a 3d model?
Thanks for the help.
