You can import a CAD assembly into SimMechanics using SimMechanics Link. The mass and inertia of each part in the assembly are imported as rigid bodies in SimMechanics. Geometry from the CAD assembly is saved to geometry files and associated with the proper body in SimMechanics. The mate definitions in the CAD assembly are imported as joints in the SimMechanics model.
Importing and Merging CAD Models into SimMechanics
Import models from CAD systems to SimMechanics™ using SimMechanics Link. Separate changes made in the CAD system and SimMechanics are automatically merged in the final model.
For SolidWorks, Pro/ENGINEER, and Autodesk Inventor models, you install a plug-in that lets you save the CAD assembly as an XML file that can be imported into SimMechanics. For other CAD systems, SimMechanics Link provides an API that you can connect to the API of your CAD system. Download SimMechanics Link.
The SimMechanics Import XML Schema enables you to import models into SimMechanics from any CAD system or modeling environment that exports an XML file that follows this schema. View and download SimMechanics Import XML Schema.
