When you create a visual aid on the Visual Aid Tools tab in NPI, you can select any element and decide which level you want it to be available for. For example, if you have a 3D CAD image view that you want to be available at all levels, you select Assembly in the Layers pane on the right side of the window. Any element assigned to the Assembly (process) level will also be available automatically at the operation, step, and activity levels. If something changes for an assembly and you need to update the visual aid, you select Assembly in the Layers pane, make the change, and that change is automatically made at the operation, step, and activity levels too.
