Gothie. Alfred State graduated their first AAS Computer
Graphics Engineering Technology (TAC/ABET) Graduates in 1983 with Martin Allen as the featured graduation speaker. The first graduating class of 18 students had over 75 job offers, launching a 20-year history of unparalleled placement success. One of the numerous "firsts" that was spun off the Alfred State program was a joint project with the New York State Department of Transportation, Region 6, to design highways and bridges and associated structures in 3-D CADDs which resulted in New York State being one of the first to use CADDS for highway design.

PDM was later made platform independent and was offered on the original IBM platform, as well as DEC/VMS and Sun/Unix - opening up its CADDS workstations to run in conjunction with this range of host platforms for product data vaulting, access/security, revision control, backup/recovery, archive/restore features.
