Eric V. Smith writes an Apple II software precursor to DataCAD called Apple Draw while studying at the University of Virginia.

"The only thing I remember about Apple Draw is that the BASIC interpreter would load the program over the frame buffer and I had some horrible hack to switch to an alternate frame buffer after loading. It somehow involved copying the frame buffer out to a floppy, then loading it back in. Needless to say, program startup was not very impressive!" -- Eric V. Smith

Formal work begins on "Integrated Software Package for Architects and Engineers."

“DataGraphic Systems, Inc. was created with the intention of providing an affordable computer system for Architectural and Engineering firms. The software is carefully designed to ease the transition problems associated with office automation. It is easy and convenient to use, and it provides meaningful advantages to the designer in terms of time savings and accuracy.”
