CAD Overlay Integration Technology, a scanning service bureau in Schenectady, New York. In January 1988 Bob Godgart, David Chassin and Michael Mayernik formed Image Systems Technology in Troy, New York. The first version of CAD Overlay was demonstrated at A/E/C trade show in Chicago in May 1988. Subsequent versions include CAD Overlay ESP, CAD Overlay GSX, and CAD Overlay LFX. In 1995, Softdesk Inc. acquired Image Systems Technology and in 1996 Autodesk acquired Softdesk. CAD Overlay was subsequently rebranded as Autodesk CADOverlay.

Computer-assisted surgery time. There are several disadvantages of computer-assisted surgery. A major disadvantage of this system is their cost. With a price tag of a million dollars , their cost is nearly prohibitive. Some people believe that improvements in technology, such as haptics, increased processor speeds, and more complex and capable software will increase the cost of these systems. Another disadvantage is the size of these systems. These systems have relatively large footprints and relatively cumbersome robotic arms. This is an important disadvantage in today's already crowded-operating rooms. It may be difficult for both the surgical team and the robot to fit
