The systems were used for industrial and business data processing, as well as for technical and scientific purposes. The popular computer-aided design software, Technovision, ran on the systems produced by Dietz, this being the result of Dietz's earlier acquisition of CAD expertise from a Switzerland-based company.[1][2]

After attempts to run the software on Dietz 600 systems, Technovision was first deployed on the Perkin-Elmer 3200 series, successor models to the Interdata 7/32 and 8/32, and employed Tektronix vector graphics terminals. The T2000 was a two-dimensional CAD system, whereas the T3000 was a two- and three-dimensional CAD product.[3]:36 After the acquisition of Dietz by Norsk Data, the products were migrated to run on the ND-500 series, also employing "vector refresh" (or refresh tube) displays, but adding support for colour raster displays.[4]
