How to flip the face of a closed 2D curve (similar to normal flip for mesh)? I use Blender 2.69. When I create a closed curve (for example, a circle) and make it 2D with the properties editor, it becomes filled.

Since I work with backface culling on (because of the application of the objects I make), only one of the sides is visible. In the case of a just created circle or a figure imported from SVG, it's the bottom side. In the latter case, it is especially annoying, because the figure appears mirrored.

Is there a simple way to flip the face (similar to flipping the normal for a mesh face) so that it shows on the opposite side of the curve?
You can swap the normal of the face by flipping the directions of the curve.


Select the curve
In edit mode go to Curve -> Segments -> Switch Direction. You can also do this via the space menu be searching for "switch direction"
