I have an autocad block consisting of a line and an attribute.
I'm looking to write a program (using AutoLISP, since I'm using ACAD for my Radiance models) that snags the start and endpoints of the line, determines the vector, and saves the xyz of the start point, the vector, and the block attribute to a text file. This text file would be used as a data file for rtrace, to keep this somewhat on topic.
Wondering if anyone had any code snippets or references for such an adventure? Sorry for the off-topic question. Email me privately if you want to.

torad - Export geometry from Autocad to Radiance slowly
The reason why you want this is that it already implements all the
transformations from within your block coordinate system to world.
Just plug in a different selection mechanism from the front, and
a different file writing routine from behind, and you're done.

Thx, Schorsch. I'll see what I can do with it.
