Rotates the view in 3D space, but constrained to horizontal and vertical orbit only.
Summary
3DORBIT activates a 3D Orbit view in the current viewport.
Selecting one of more objects before starting this command limits the display to those objects only.
The 3D Orbit cursor icon appears. If you drag the cursor horizontally, the camera moves parallel to the XY plane of the world coordinate system (WCS). If you drag the cursor vertically, the camera moves along the Z axis.
While the command is active, right-click to display additional options from a shortcut menu.
