Click on a CAD body in the graphics pane, or type its identifier in the Select box to select the CAD model you want to modify. Then click Apply to open the model in Autodesk Inventor Fusion.
Note: Assemblies contain more than one CAD body but are treated as a single model when using this tool. If you select a CAD body that is a component of an assembly, the entire assembly is exported to Autodesk Inventor Fusion.
Remember: When you finish modifying the geometry, click Return to Moldflow (Autodesk Inventor Fusion). The Autodesk Inventor Fusion program closes, and the modified CAD model is imported automatically into a new study in the current Autodesk Simulation Moldflow Insight project.
