Manager, The Newton Project

1995

Responsible for developing a software architecture on which the company can base its next generation of CAD products. Formulated the requirements, led design and implementation team, and created a demonstration for investors. In this project, my group developed a special language, in which arbitrary CAD objects could be defined.

Another part of the infrastructure was a universal solver engine, driven by the CAD object definitions. The solver was able to process both equation-type (bi-directional) constraints, and procedure-type (unidirectional) constraints. The entire system was optimized for incremental addition and removal of constraints, and was architected as a client-server application, to allow concurrent work on the same CAD model by multiple clients. The project was done on Windows NT in Visual C++/MFC.
