Compatibility & Scope
Intended for Windows AutoCAD with AutoLISP, DCL, and ActiveX support. Source-level layout checks passed; testing inside your AutoCAD release is still required.
This version places one fixture type per run in rectangular rooms. It creates drafting layouts and quantity reports; it does not calculate lighting performance, airflow, electrical loads, or code compliance, or detect collisions with existing drawing objects.
