Design Simulation Technologies develops, markets, and supports software products used by students, educators, and professionals to learn and teach physics principles and to use these principles to build virtual models of mechanical designs. High School and College students and educators use Interactive Physics to investigate and experiment with concept in physics. University students and educators use Working Model 2D to understand how mechanical systems work and perform without building physical models. Professional Engineers use Working Model 2D and Dynamic Designer Motion to build virtual prototypes of their mechanical designs and use these prototypes to evaluate performance.
