I have several LISP programs used to insert blocks using different formats and I would like to start using c3d points. I have written many LISP functions but have been out of the loop and am very rusty. Also, still learning C3D, I have used LISP programs for years to get along without.
Attached is my file for reading OPUS files from the NGS and inserting a block. Need to change this to insert color point.
