The Flip command reverses the normal direction of a curve or surface.


Select objects.

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.
