July 2002 - D-Cubed announces the latest release of the HLM and CDM, its kernel-independent, accurate, fast and reliable hidden line and collision/clearance components.
Hidden Line Manager, version 2.8.0
In addition to a continuous focus on performance enhancements this latest release of the HLM includes new functionality to enhance the clarity and aesthetic appeal of the hidden line views seen in a variety of applications, from mechanical CAD systems through to technical illustration products.
The hidden line view enhancements are due to the HLM's new ability to identify the edges that form the perimeter and internal holes of a part or assembly. These edges define the boundary of a shadow that would be cast by a model from a certain view direction, this boundary being known as the 'global outline'. An application would typically thicken the display of the edges forming the global outline, the results of which can be seen on our website.
As well as enhancing hidden line views, the global outline can also assist with the programming of machine tools by CAM applications. The offset of the outline of many mechanical parts when viewed along a major axis, defines the path taken by a tool when machining the outer perimeter and internal pockets of such parts.
Further developments in this release include improved tolerance to inaccurate models. Being kernel independent, the HLM has been designed from the outset to be able to handle reliably the vast range of model formats found in the CAD industry. Inaccurate models often arise when models are transferred between different CAD systems running different modellers, including those models that go through an intermediate neutral format such as IGES or STEP.
Collision Detection Manager, version 2.8.0
This latest release of the CDM further enhances performance and flexibility by providing applications with a wider variety of choices over exactly what information is computed by the CDM. The choices include the ability to stop the computation after the first collision is found, to find all parts that collide, to find all faces that collide, and to identify for any part the list of other parts with which it is colliding.
About the HLM and CDM
The HLM, first released in 1999, is already one of the most widely deployed hidden line solutions in the CAD field, being used in numerous applications, including several Autodesk product lines, such as AutoCAD, Mechanical Desktop and Inventor. Its kernel independence enables a dedicated team of experts to focus exclusively and continuously on the development of advanced hidden line algorithms without being distracted by the wider requirements of a general modelling technology.
Also released in 1999, the CDM has rapidly achieved broad market acceptance, particularly with mid-range mechanical CAD applications, including Inventor from Autodesk, Solid Edge from EDS PLM Solutions and SolidWorks from SolidWorks Corporation. The CDM's success is due to a range of novel algorithms specifically designed to detect collisions on accurate solids in an interactive assembly environment, rather than being derived from the traditional, and unnecessarily intensive, Boolean approach. Commonly used in conjunction with D-Cubeds 3D DCM interactive assembly part positioning and kinematic solving component, the CDM allows designers to interact with their assembly models with a heightened sense of realism and solidity, eliminating design errors caused by interpenetrating parts.
About D-Cubed Ltd.
Founded in 1989 in Cambridge, England, D-Cubed provides software components and technical consulting services to the CAD/CAM/CAE application development industry in all areas of geometric, solid and variational/parametric modelling. Most of the worlds leading CAD vendors have adopted one or more of D-Cubeds widely respected component technologies for integration into their end-user applications. We have never developed, and do not intend to develop, our own end-user applications. This focus avoids any competitive conflicts of interest with our customers. www.d-cubed.co.uk
