Kristen,
I’ve been using a program called Autolux for years. It works inside autocad. It was developed by a company that tested luminaire output for manufacturers. The company was recently acquired by Keysoft Solutions. I have not upgraded my software with Keysoft but they seem to have kept it the same. Here is a link: https://www.keysoftsolutions.com/products/keysoft-traffic/autolux/.
I hope this helps,
Tim
