Bentley Extends Commitment to Siemens PLM Software

The 3D computed-aided design (CAD) world continues to be co-opetitive. Many of the situations where fierce competitors end up using each other’s tools in their competing products are circumstantial, i.e., those products were using tools supplied by a software company before it was acquired by a competitor.

For example, the Parasolid 3D geometric modeling kernel was developed originally by ShapeData and was used by SolidWorks well before Dassault Systèmes acquired Solidworks and before Siemens acquired Parasolid via UGS.

In any case, in support of its MicroStation V8i (SELECTseries 3) software products, Bentley Systems, Incorporated, will now add Parasolid Bodyshop, and D-Cubed Profile Geometry Manager (PGM), and expand the deployment of the JT Data Format. Bentley expressed its interest in the ability of Bodyshop to “heal” (i.e., repair, optimize, and validate) imperfect 3D geometry imported from third-party CAD systems. For its part, D-Cubed is a geometry constraint solver and a set of calculation libraries that have been modularized and can be used with other Siemens and non-Siemens modules or solutions. It is often used together with Parasolid by CAx developers.

The interoperable JT data format is widely used throughout the world for sharing mechanical 3D information among multiple organizations and throughout manufacturing supply chains. Due to the widespread adoption of JT throughout the PLM software industry, the JT file format reference document has already been accepted by the International Organization for Standardization (ISO) as a publicly available specification (PAS). But a formal process is still underway to establish the JT format itself as an ISO standard for lightweight 3D data, reportedly some additional clarification being requested by some ISO review board members.

Siemens should hereby benefit from the growing presence of its versatile software components in the architectural, engineering, and construction (AEC) software industry, where it hasn’t really been a leader, and where it hopes to catch up with Autodesk. In addition, this endorsement by Bentley should come as a consolation, given the ISO hurdles for JT and Dassault Systèmes’ recent decision to decouple the SolidWorks business logic from Parasolid and to continue with a dual kernel product strategy (the Parasolid and the CATIA kernels).
