Click the menu icon to perform this plugin.

After the plugin is selected, select the required orthogonal projection view tab. Then click a control point of the required surface.

The order of control point rows for the selected surface is reversed. You can verify the order by enabling Annotations under the View menu and checking the "i" index of the control points.

Note that the orientation of the surface is reversed (the normals will point in the opposite direction).

Click the menu item to disable the plugin mode.
