The Flip command reverses the normal direction of a curve or surface.
The command line reports the number of objects flipped.
|Closed polysurfaces cannot have their normal direction facing toward the interior of the object.
|The curve and surface directions affect the results of many surface creation commands and Boolean operations. If Boolean operations give unexpected results, such as a union instead of a difference, try flipping the normal direction of one or both of the surfaces.
