CAD (Computer-aided design) software allows for a more efficient process of obtaining the perfect final image or video. Aspects such as lighting, prop design, venue scouting can often be an incredibly time-consuming process, but when done by 3D designers, the various possibilities of product set-up and can be virtually endless. It also gives companies much more freedom in regards to the ways they want to portray their products.
