3D Geometric Constraint Solving for Assembly Constraints, Kinematic Simulation, 3D sketching and Part Shape Control

Integrating the D-Cubed 3D DCM (Dimensional Constraint Manager) component into your software application provides a geometric constraint solving capability that enables your end-users to:

• Position parts in assemblies using a wide range of driving dimensions and assembly constraints.
• Simulate the kinematic behavior of constrained assemblies and mechanisms.
• Control the shape of parts without relying on a design history, sometimes known as direct editing or direct modeling.
• Configure 3D sketches in support of 3D features, 3D pipe/wire routes and surface definition from freeform curves.

The 3D DCM provides the geometric constraint solving in many popular parametric modeling systems. See our list of application areas for more details. Our large customer base, with hundreds of thousands of end-users, drives investment in quality and functionality over the long-term.

Flexible licensing arrangements and a simple integration process enable your organization to add the 3D DCM to your applications quickly and economically. For a step-by-step description of how the 3D DCM is used in an application, view our product tour, or request your own demo application or technical overview .
