Description: In general, you cannot use the Edit Mesh toolset to modify the mesh of a dependent part instance; however, you can now move the nodes of a dependent part instance using the Edit tool in the Edit Mesh toolset. Similarly, you can project the nodes of a dependent part instance onto selected geometry—such as a face or an edge—of an unassociated part instance using the Project tool. Abaqus/CAE moves or projects the nodes of the original meshed part, and your modifications appear on all dependent instances of the part. For example, you can move the nodes of a part instance until they are close enough to be within the node merging tolerance.
