Bentley Systems Licenses D-Cubed 2D DCM, 3D DCM and CDM Components from Siemens PLM Software and Extends Commitment to Parasolid

PLANO, Texas, October 16, 2007 – Siemens PLM Software, a division of Siemens Automation and Drives (A&D) and a leading global provider of product lifecycle management (PLM) software and services, and Bentley Systems, Inc. of Exton, PA, a leading provider of solutions for the lifecycle of the world’s infrastructure, today announced that the D Cubed™ 2D and 3D Dimensional Constraint Managers (2D DCM and 3D DCM) and the Collision Detection Manager (CDM) software components have been licensed for use in the MicroStation® platform which is widely adopted for the design and management of buildings, civil engineering projects, process and power plants and geospatial information. In addition, Siemens PLM Software and Bentley Systems announced a multi-year extension to their long-standing, successful deployment of Parasolid® software as the 3D geometric modeling component for MicroStation.

PLM Components are well known for their use in a wide range of mechanical CAD applications. Various solutions from the portfolio have been deployed in NX™ software and Solid Edge™ software from Siemens PLM Software Inc., SolidWorks® software from SolidWorks Corporation, Autodesk Inventor® software from Autodesk Inc., and many other products. The new agreement with Bentley is one of the most significant endorsements of the D-Cubed components by an architecture, engineering and construction (AEC) vendor in the 18-year history of the D-Cubed product line. Building on the Parasolid geometry modeling kernel, these PLM Components will enable Bentley to bring sophisticated design techniques, already proven in mechanical CAD applications, to the AEC marketplace.

“The AEC industry is moving in exciting new directions. Technologies such as Building Information Modeling (BIM) and Bentley’s own GenerativeComponents are vastly increasing the number of design configurations that architects and engineers can explore. Significant design changes can now be made more rapidly, more easily, and more economically than ever before,” said Shaun Sewall, Vice President of Platform Products and Technology at Bentley Systems. “The D-Cubed components are an important part of our strategy to provide advanced parametric design capability to our users. Our experience with Parasolid, and our strong business relationship with the Siemens PLM Software team over the past 10 years, left us in no doubt that this extension to our partnership was the right choice.”

“We are confident that the extended application of Siemens’ PLM Components will reinforce Bentley’s reputation for technical excellence and innovation in the AEC market,” said Chuck Grindstaff, executive vice president, Products for Siemens PLM Software. “As the leading provider of open solid modeling and parametric design capabilities to the global mechanical CAD industry, we are delighted with this significant step forward in our contribution to leading AEC applications.”

About PLM Components; Parasolid and D-Cubed

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. Siemens 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 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.
