If you delete a source marker, a dialog box appears informing you that deleting a source marker will also delete the viewpoint and any markers linked to it.
However, the same dialog box gives you a different option: delete the source marker, but keep the viewpoint as an independent viewpoint with no model source.
Deleting a linked marker has no effect on any other element.
