CAD Import Module, Design Module, and LiveLink™ Products for CAD
New Functionality in Version 6.4
•
The CAD Import Module, the Design Module, and the LiveLink™ products for CAD utilize the Parasolid® geometry kernel from Siemens PLM for solid modeling operations, geometry repair, and defeaturing. (Without these products, a COMSOL-native geometry modeling kernel is used.) The CAD Import Module released with COMSOL® version 6.4 includes an upgraded version of the Parasolid kernel. As a result, a number of stability issues have been fixed, which makes geometry modeling operations and the import of CAD models more robust.
•
The CAD file import and export functionality included with these products has been extended to support new versions for some of the supported file formats (for details, see under Read from File, CAD on www.comsol.com/products/specifications/cad/).
•
When importing CAD assemblies saved in the file formats of the CATIA® V5, Inventor®, NX®, PTC Creo Parametric™, PTC Pro/ENGINEER®, and SOLIDWORKS® software, it is now possible to display a 3D preview of the assembly components in the Graphics window. You can use this preview to choose the components to import from the assembly.
•
The Import feature for CAD files has been updated with the new Fix errors list with the choices Automatic, On, and Off for detecting and repairing geometric errors during importing. The following checkboxes have also been added for simplifying and repairing: Delete small details, Heal edges, Minimize tolerances.
•
The settings for the Repair feature now include the following new checkboxes for simplifying and repairing objects: Fix errors, Delete small details, Heal edges, Minimize tolerances.
