What is Torad:

Torad is an autolisp application for Autocad R11-R14 for exporting geometry data to the RADIANCE lighting simulation package.

Basic features of torad are:

Entities exported (by choice):
    Autocad 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 quadrilateral polygons.
    - extruded arcs              -  quadrilateral polygons.
    - extruded lines             -  quadrilateral polygons.
    - extruded 2d-plines         -  quadrilateral polygons.
    - wide 2d-plines             -  multilateral polygons.
    - closed 2d-plines           -  multilateral polygons.
    - 3d-meshes                  -  triangular or quadrilateral polygons.
    - polyfaces                  -  triangular or quadrilateral polygons.
    - points                     -  spheres or bubbles.
torad is optimized for speed and memory usage as far as possible without loosing the functionality of sorting entities to seperate files. If you still consider it to be too slow, you will have to resort to Radout, a transscript of torad to ADS-C by Philip Thompson at MIT.
There is also a user interface in the works for radout (and radiance), which will allow to control most of the rendering parameters from within autocad.

the complete program consists of eight files:

    Program files:
        torad.lsp       Main program source file.
        esample.lsp     Entities sampling and conversion source file.
        vector.lsp      Geometrical utilities source file.
        torad.dcl       Dialog box definition file for Autocad 12.
        torad.mnu/x     Menu file for setup with Autocad 10/11.

    Additional Files: 
        torad.man       User manual. 
        torad.README    This file. 
All these files are packaged in both a compressed tar file and a zip archieve to make them easily accessible for users of each unix and dos systems.

"support"

I expect the program and the manual to be self explanatory for users who have at least some experiance with either Autocad, Radiance or better both of them. If there still remain questions that cannot be answered neither through the manuals and FAQs to Autocad, RADIANCE or torad nor by the local guru, you might try to mail me at the address below.

Be sure to notify me if you think you have found a bug in this program (there still might be some although thoroughly tested).
