Dr. Kaiman Lee began his career in computer aided design in 1969. His initial four years were devoted to the development and management of ARK-2, the world's first turnkey interactive graphics system for architects. He was the Computer/Architect Coordinator for Perry, Dean & Stewart, Architects/Planners, Boston, MA. ("The major, early pioneer in this (CADD) effort was the Boston-based firm of Perry, Dean and Stewart. In an effort led by Kaiman Lee, the firm invested heavily in developing the ARK/2 system." --- Howard Birnbert, in "A brief journey through time: technological advancements in the A/E/C industry," in CE News Dec. 2001)

Dr. Lee was the major contributor to "The Computer in Architecture," a 15-minute, 16 mm professional marketing film, the first in that era.

Dr. Lee was elected Chairman of the Special Interest Group in Interactive Graphics of Digital Equipment Corporation (DEC) User Society in 1972:

His next ten years were diversified into CAD consulting, speaking, writing and publishing.

In 1982, he was recruited by the Naval Facilities Engineering Command (NAVFAC) as their Western Division's CAD manager (Head and Systems Manager, Computer Graphics Branch). He built the best NAVFAC-wide CAD system implementation from inception.

Next, he was promoted to be the CAD leader (Senior Program Manager of Graphics Engineering & Mapping System and Computer Aided Design) at NAVFAC headquarters.

Dr. Lee was the first to lead NAVFAC in the use of personal computers for CAD through the Engineering Microcomputer Graphics (EMG) program. He also implemented the contracting and negotiation of CAD deliverables for facilities design contracts.

Dr. Lee introduced Architectural-Engineering-Construction (AEC) line fonts and hatch patterns and ultimately had them incorporated in the Initial Graphics Exchange Specification (IGES) Version V in October 1990.
