Reviewing wave-linked geometry with PMI elements

In some cases, product manufacturing information (PMI) elements reference geometry that is not defined in an actual part occurrence, but rather in geometry stored in the upper assembly level of the model in NX.

To save time, wave-linked geometry such as a face, body, line, or curve (called features in NX) is copied and linked from a nominal part component in a lower-level assembly so that you can associate it with other components, such as PMI elements. You can then display wave-linked parts to which PMI elements are connected in detailed views by clicking to show the wave-linked face, body, or curve of the part in the Viewer (wave linked geometry is displayed in orange in the example below).

Note

A PMI element might be specific to the visible wave-linked feature. For example, it might measure the length of a curve.
