Released September 2007
UGS PLM Software announces the latest release of the D-Cubed Collision Detection Manager (CDM), a software component that accurately and rapidly detects collisions and computes clearances. New enhancements specific to version 37.0 are listed below. See the full product description.
Collision calculations between parametric surfaces can be computationally intensive. However, on occasion, an application or end-user will know that certain parametric surfaces are not relevant to a particular collision analysis. For such occasions the CDM enables the irrelevant surfaces to be removed from the collision or clearance computation, thus improving performance with no impact on the final result. The CDM also has the ability to reduce memory usage by representing identical parts using instances of a reference part. The new capability introduced in this release is to control removal of irrelevant surfaces across all instances of a reference part using just the reference part. The benefit is a more efficient application process for maintaining consistency when using instanced parts.
One of the main benefits of the CDM is its fast and robust computations on a wide variety of geometry types, including analytics (lines, circles, planes, cylinders, tori, etc.) and parametrics (e.g. NURBS). To achieve its combination of performance and reliability, specific algorithms have been developed to handle collision computations between most permutations of geometry types. In this latest release, new algorithms have been added improving the intersection computations between some analytic geometry types.
The D-Cubed components are integrated into a wide range of applications. Hence, they are available for a wide range of application development environments which are continually being extended to keep pace with customer requirements. This release sees the addition of support for 32 and 64 bit versions of Windows Vista, Linux Suse v10, Linux Red Hat Enterprise 5 and the Intel 32-bit processor version of Mac OS X.
First released in 1999, the CDM enables end-users to interact with their models with much improved realism and solidity, greatly reducing errors caused by interpenetrating parts. Operating in assembly, mechanism, machining and measuring simulation environments, it offers a range of novel 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. The CDM is compatible with any application as it is independent of any particular modeler or model format, operating on exact, faceted, solid or surface representations.
UGS PLM Components are software tools that can help increase the profitability of software applications in the CAD, CAM, CAE and PLM marketplace by raising their value and lowering their costs. This is achieved by supporting innovation and interoperability with standard tools that ensure quality and reduce time to market. UGS PLM Software develops these components, uses them throughout its own applications and licenses them to independent software vendors and end-user organizations. Flexible licensing arrangements and a simple, proven integration process enable any organisation, large or small, to bring innovative capabilities to their applications quickly and economically. Part of the UGS PLM Components family of products, the Parasolid and D-Cubed components provide 3D part and assembly modeling, editing and interoperability, 2D/3D parametric sketching, motion simulation, collision detection, clearance measurement and visualization. Applications include mechanical CAD, CAM, CAE, mold design, sheet metal, AEC, GIS, structural, plant and ship design, CMM, reverse engineering and sales configuration.
