Between 1999 and 2017, Tehnif Software worked in partnership with Chicago Stage Equipment Co. Inc. DBA Design & Drafting. We combined lighting, sound, video, set design and event planning into an ALL-IN-ONE CAD program - LD Assistant. For many years, CAD-N-LIGHTING.com website served as LD Assistant user's community, a place where lighting designers exhibited their work, where users stayed in contact each other and with LD Assistant software development team. Today, if your activity has a connection with 2D Drafting, 3D Modeling, Lighting Design, Audio & Video, Event Planning, Rendering & Animation, Visualization & DMX Control, LD Assistant or CAD, is good to know that CAD-N-LIGHTING.com remains a place where you can keep in touch with people who share the same passions.

In May 2017, Chicago Stage Equipment Co. Inc. DBA Design & Drafting, announced the ceasing of all further development of LD Assistant lighting design software. View PLSN announcement ↗
