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.

LD Assistant is a Lighting Design Software for Stage Lighting, Audio, Video and Event Planning, that merges advanced lighting design algorithms with 2D & 3D standard CAD tool set.

Drawings are made up of objects. You can create a range of objects, from simple lines and circles to spline curves, and ellipses. When specifying a point, you can enter distances, offsets, and measured intervals.

A realistic rendering of a model can often give a product team or prospective client a clearer vision of a conceptual design than a plotted drawing. Rendering creates a 2D image based on your 3D scene.

... it’s difficult to embrace all of LD Assistant’s features; therein lies the beauty of the program. Power users will never exhaust all the potential of the software, but they are consistently able to push the envelope of their own designs.

For adding the powerful 3D rendering tools of Viz 4 and Lightscape and credibility of IES standard photometrics to entertainment designer’s toolboxes – and making them user friendly enough to use without three new textbooks – we recognize Design and Drafting’s LD Assistant Ac with VIZlink.

We understand much more than just CAD ... we understand Design, and more importantly, we understand users business. Our software solutions successfully combines lighting and event planning into an ALL-IN-ONE product.

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.
