The computer model of the USS Holland began in 1992 as a training exercise. It was built using Electric Boat’s computers and Dassault’s CATIA software. The original model was built with CATIA version 3 using mockup (approximate) solids, but it has evolved as Electirc Boat implemented new versions of CATIA and additional Product Lifecycle Management (PLM) tools. The current version of the computer model consists of more than 2200 piece parts.
Based on the available information, some portions of the submarine can be modeled to the level of rivet holes. Unfortunately, other portions remain a complete mystery. Although the plans and specifications refer to a bilge pump, a hydraulic pump, fans and lights, no details have been uncovered to date.
The individual parts of the submarine were modeled by combining 3D primitives such as cubes, cylinders and offset surfaces. The parts were stored in Electric Boat’s production database and organized into a system based product structure.

This computer model has been used to investigate and illustrate the systems on board the U.S.S. Holland and to evaluate Product Lifecycle Management products from IBM and Dassault Systems. Kinematic mechanisms have been defined for the engine, motor, clutches, shafts, hatches, switchboard, rheostats, and some of the valves allowing many routine operations such as propulsion plant operation, loading weapons and firing weapons to be animated and viewed in real time.
