Enhancements introduced in version 52.0 of D-Cubed CDM (Collision Detection Manager) include:
Recent releases of CDM have seen major improvements to the handling of tolerant geometry. Tolerant data can arise when a model is translated from one CAD format to another, for example. Some elements of the model may be locally much less accurate than is typical of solid model data. These regions of the model can require special treatment for various operations, including collision and clearance computations.
The improved handling of tolerant geometry is computationally intensive. Following the successful focus on functionality and reliability in this area over recent releases, the latest release puts the emphasis on performance optimisation.
D-Cubed CDM (Collision Detection Manager) is a software component that offers collision detection and clearance distance measurement for solid, surface and wireframe models. It supports accurate, tolerant and faceted geometry. Used in assembly, mechanism, machining and measurement simulation environments, CDM offers a range of algorithms to interactively detect collisions and compute clearances, even on large, complex assemblies. Performance is particularly excellent for repeated computations on models that are in motion. CDM is compatible with most applications, being independent of any particular modeler or model format.
