Change View > Rotate Positive around Z-Axis (3D Menu)

Use this command to rotate the current 3D space's view by one increment as defined in Options around the Z-axis.

Changes to the view (i.e. the position and representation of the 3D space relative to the 2D world) cannot be undone using normal Undo, but only using 3D > View Preset > Undo. Alternatively, you can save one view in each room using 3D > View Preset > Save Current View and restore it later using 3D > View Preset > Retrieve Saved View.
