Invert face's normal direction

Hi,
Is there any way to inver face’s normal direction without re-creating this face?
Thanks.

Yes, select the face and ctrl-n (recalculate outside) ctrl-shift-n (recalculate inside) . There’s also in panel mesh<normals<recalculate…:eyebrowlift:

Many thanks :slight_smile:

Or, just to flip the normals (since recalculation isn’t always correct on planes), w -> Flip Normals.
