Dimensional Constraint Manager (DCM) components for variational modeling is an application of the 3D DCM in direct 3D variational control of the shape of CAD models. Until now, the 3D DCM has focused on assembly positioning and mechanism simulation applications, in which each part is treated as a rigid object. Direct variational part modeling is a topical new area of functionality, enabling CAD systems to reduce their reliance on older, less powerful, history-based techniques.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
