From MVN 2019.2 and up it is possible to hide unused segments. This can be helpful to better visualize the segments of interest in MVN when working with a suit configuration that does not have all segments in it.
Hide/Unhide Unused Segments
To hide or unhide the unused segments go to the "Options" tab and click "Preferences". In the Preferences menu go to 3D View to get access to "Hide Unused Segments". By default, this parameter is set to checked, meaning that unused segments are hidden. To unhide, simply uncheck this parameter.
