DXFImporter

"Script for importing Autocad .DXF files. The .DXF format is a popular industry standard CAD (Computer Aided Design) format and is provided as an export option by most 3D modelling packages.
Version 1.1 Update: now correctly handles polyline meshes. If you're experiencing problems where your models are imported as a huge mangled heap of triangles all coming out of a single point. then this upgrade is for you! If you're not experiencing problems of this nature. consider this upgrade optional."
