Invert

Menu access: Shape | Surfacic / boolean operations | Invert

Description:

Allows you to invert the normal of a surface.

General philosophy:

Select the surface to invert.

Specific point(s):

For example, this function can be useful if you need to replace a trimming surface by another one. Actually, the side of the trimming is based on the direction of the surface normal. So if you want the trimming to stay the same, the normal of the new surface must be the same than the first one.
