The following exercises illustrate how you can add motion to a model that has been created in a CAD software package. You can create CAD assemblies in such a way that they map into MSC.visualNastran Desktop very cleanly. When you design assemblies with "motion in mind," they can be imported easily and their motion simulated immediately.

In these exercises, you will add motion to an assembly that has been fitted together with no regard to motion. Although you will have to clean up a few constraints in the imported CAD model, MSC.visualNastran Desktop makes it easy to simulate the motion of the assembly.

To complete any of the exercises, you must have one of the following software installed on your computer in addition to MSC.visualNastran Desktop.

You can follow the steps in this exercise using any of the supported CAD packages â Autodesk Inventor, Mechanical Desktop, Pro/ENGINEER, Solid Edge, or SolidWorks. Go to the section for your CAD package and follow the steps. Look for the icon that identifies your CAD package.
