Dxf2rad is a command line utility for translating geometry data from the DXF file format into the format understood by the Radiance lighting simulation package.

Dxf2rad shares a lot of code with Radout, an Autocad extension to export geometry directly from within a drawing. It was written to support the architectural lighting design software package Rayfront, which offers complete control over all parameters of Radiance simulations.

• Any DXF file in a valid format as specified with any release of Autocad can be converted.
• All hiding/shading entities from Autocad can be converted, and some more (ACIS solids in DXF files by R14 and Autocad 2000, as well as other objects defined by third party applications are not supported).
• Blocks are fully supported, as long as the file actually contains their definitions.
• Output primitives will have modifiers based on the layer of each entity in the form "l_<layer>". Floating layers within blocks are fully supported.
• The output can be scaled by an arbitrary factor.
• Entity types can be filtered through command line switches.
• Option to write each named view defined in the DXF file into a Radiance view file. (new in 1.1)

Entities exported (by choice):

DXF entities:	Radiance objects:
3dfaces	triangular or quadrilateral polygons
extruded or flat traces	triangular and/or quadrilateral polygons
extruded or flat solids	triangular and/or quadrilateral polygons
extruded or flat circles	rings and cylinders/tubes
extruded arcs	quadrilateral polygons
extruded lines	quadrilateral polygons
extruded 2d-(lw)plines	quadrilateral polygons
wide 2d-(lw)plines	multi- and quadrilateral polygons
closed 2d-(lw)plines	multi- and quadrilateral polygons
3d-meshes	triangular or quadrilateral polygons
polyfaces	triangular or quadrilateral polygons
points	spheres or bubbles
