If I understand you correctly (I may be wrong) I think that what you 
need to do is 'export' your .dxf or .obj to POV-Ray using Poseray. This 
generates a couple of files (MyObject_POV_geom.inc and 
MyObject_POV_mat.inc) containing a mesh2{} file that describes the 
original geometry and textures, and which you can then render in POV-Ray 
as an object{}. You may probably need to edit the material file.
