Industry:         Mechanical Engineering Simulation Software

Company description: Working Model Inc. was formed in April 1997 as a division of Knowledge Revolution to strategically market and sell solutions to the mechanical engineering market. Knowledge Revolution was founded in 1989 to address the emerging market for the simulation of mechanical systems. Knowledge Revolution is now the leading unit provider of software that allows users to model and animate mechanical systems.

The company's principal product, Working Model(R), provides an environment for the design, analysis, and distribution of virtual mechanical prototypes on Windows/NT computers. The company's motion simulation technology is also used in Interactive Physics(TM), which has become the standard in educational physics software worldwide.

Working Model is a solution for the design and specification of mechanical systems. With Working Model, mechanical engineers can perform design studies without building physical prototypes. By making low-cost, easy to use virtual prototyping technology available to many more engineers within an organization, Working Model increases the amount of design work that can be performed prior to creating physical prototypes. With Working Model, companies can design better products and bring them to market more quickly.
