About Reopening Assemblies After Modifying Intersected Components in Source Models
You can add or remove the assembly-level features that intersect the components of Autodesk Inventor, NX, and SolidWorks assemblies in their source models. All such changes are preserved in the intersected components until you reopen the Autodesk Inventor, NX, and SolidWorks assemblies in Creo. When you reopen the non-Creo assemblies, the component changes are propagated and the intersected components are updated with the changes.
The non-Creo assembly models that you reopen in Creo reflect the following assembly-level changes:
If additional components of the non-Creo assemblies were intersected with the assembly-level features in the source models, more components are represented as the intersected components in the reopened assemblies. The additionally intersected components replace the regular components and their occurrences in the reopened non-Creo assemblies to maintain the assembly structures.
If the intersecting features were removed from components in the non-Creo source models, the components in the reopened assemblies reflect these changes. The regular components of the reopened assemblies replace those components whose intersecting features were removed in the source models.
References created when you add or remove the intersecting features from components in the source models of the non-Creo assemblies can fail when the components are replaced by regular or intersected components. You must then resolve the failing references.
