Several makes of microcomputers are linked to digitizers, graphics tablets, and plotters for use in computer-aided design (CAD) work, as well as production of three-dimensional views, maps, charts, and animation. Extensive software is available for student and faculty use. The terminals are linked into the University Computing Resource Center for expanded mainframe capabilities. Micromodems link the College of Architecture computer systems to external sources of data. The College also has several computer-aided design systems, as well as a simulation laboratory that features new technologies in still photography and video photography, combined with computer hardware and software, to create visual simulations of the built environment. The College of Architecture offers a number of courses in computer applications for design and planning.
