The 3D view menu holds various commands to adjust the visible view port
of a 3D data view. Commands
are specifically designed to zoom, scale, shift, rotate and scroll analytical
3D data to fit the user requirements for printing or further evaluation.
Why is the menu missing sometimes?
The 3D view menu is only available if the current active object is a 3D data object.
The 3D
Preferences dialog is also available via the context menu on
a data view. Just click the Right
Mouse button over a 3D data view to enter the context menu and
select the Preferences... command.
