Importing CAD Models

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 a CAD Suspension Assembly into SimMechanics 2:57
Import a CAD assembly to SimMechanics™ using SimMechanics Link. Add tire model and steering system, and automate toe and camber tests using MATLAB®.

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.

Piston model imported from CAD into SimMechanics.
Piston model imported from CAD into SimMechanics. After the CAD model of the piston (top left) is saved as an XML file, and imported into SimMechanics (bottom), the visualization is generated from the STL files automatically exported from the CAD system (right).
