This became particularly evident in 1992 when Autodesk released AutoCAD 12 for Macintosh. These DOS descending CADs had the pointing device as the tablet–as in the concept of CAD on workstations–used also by AutoCAD of Autodesk. Here, however, right from the start there was a big difference between the Mac CAD programs, deriving from the MacDraw philosophy with its mouse pointing device, and the CAD programs, first on DOS and later Windows, deriving from the Command Line philosophy. Soon after came the architectural programs Radar CH, Architrion and Domus.Cad. Of these early CADs, we might mention MacDraft, PowerDraw and MiniCAD. MacDraw was the prototype of all vectorial graphic software such as Freehand and Illustrator, these too were created on Macintosh, as well as for a series of CAD programs that borrowed from MacDraw the concepts of a simple, intuitive user interface and visual control of the final result.
