Siemens Digital Industries Software has updated Parasolid, its open software technology for geometric modeling. The latest release expands on convergent modeling for generative engineering, 3D-printing and reverse engineering applications, adding new tools that integrate previously incompatible facet and boundary representation (B-rep) data formats within a single modeling session. Siemens says this enhanced support for mixed models can help drive significant productivity gains by eliminating the need for time-consuming model conversion and allowing users to apply classic design techniques directly to facet models.

Parasolid’s update also allows it to add further value to design and engineering workflows in many different applications by allowing users to intersect meshes with all classic B-rep surface types and perform more sophisticated configurations of fillets and chamfers on mixed models. In addition, there are new tools for direct editing of faces and for rendering and repairing mixed models. The update also enhances B-rep in areas such as blending, sweeping, non-uniform scaling and rendering, bringing users gains in modeling flexibility and performance.

Siemens uses the Parasolid geometric modeling kernel in its own Solid Edge and NX software, and it serves as the core of the Xcelerator portfolio’s open and flexible ecosystem. The company also says Parasolid is used in over 350 other applications from industry-leading CAD/CAM/CAE/AEC software vendors.
