Claris CAD Claris CAD Claris CAD was a two-dimensional computer-aided design program for Apple Inc. Macintosh. Claris CAD was developed in 1988 by Claris Corporation in a joint effort with Craig S. Young of Computer Aided Systems for Engineering (CASE). It was based on MacDraw II and Young's earlier CAD application, "EZ-Draft". Version 1 was released in 1989 for Macintosh computers running System Software 6 or later. The initial releases were plagued with bugs, especially with the bundled plotter driver. Development halted in June 1991 with the release of version 2.0.3. Currently, Claris CAD can be run on older Macintoshes using the
Computer-aided dispatch mobile data terminals (MDTs) or mobile data computers (MDCs). CAD systems consist of several modules that provide services at multiple levels in a dispatch center and in the field of public safety. These services include call input, call dispatching, call status maintenance, event notes, field unit status and tracking, and call resolution and disposition. CAD systems also include interfaces that permit the software to provide services to dispatchers, calltakers, and field personnel with respect to control and use of analog radio and telephone equipment, as well as logger-recorder functions. Computer-assisted dispatch systems use one or more servers located in a
