A design aid tool for testing and development of daylighting systems was developed. A simplified ray tracing software was programmed in Lisp for AutoCad. Only fully specularly reflective, fully transparent and fully absorbant surfaces can be defined in the software. The software is therefore best suited to evaluation of light transmission through specularly reflective daylighting systems. A graphic and numeric display of arrays for each incident angle aids the user in the ray tracing analysis. The results are automatically written to a text file for easy import and analysis in a spreadsheet.
