Developed and marketed by Image Systems Technology, CAD Overlay was first released in January 1988 running on AutoCAD Version 2.6. CAD Overlay replaced the previous generation of automatic raster-to-vector translation systems by embedding scanned documents and images directly in the CAD system.
CAD Overlay was derived from a custom AutoCAD application developed using the Nth Engine graphics board in 1987 by David Chassin for Image 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.[1]
The first version of CAD Overlay was demonstrated at A/E/C trade show in Chicago in May 1988.[1] Subsequent versions include CAD Overlay ESP, CAD Overlay GSX, and CAD Overlay LFX.[2]
In 1995, Softdesk Inc. acquired Image Systems Technology and in 1996 Autodesk acquired Softdesk,.[3] CAD Overlay was subsequently rebranded as Autodesk CADOverlay.[4]
