The setting options refer to the 3D views in the PARTdataManager, PARTproject or PARTdesigner modules, not to the 3D view in 3Dfindit.
The display (component, background) within the 3D preview [Preview 3D] is controlled on the 3D settings Tabbed page. There are also setting options for the system-internal graphical operating processes.
The dialogs are divided into the Elements, Environment and Miscellaneous Tabbed pages.
