Before I got the option to be able to flip the UV normals in the options menu running the Dir Function but now there is no option I have attached a photo below showing the command options…
Moved to Rhino for Mac from Uncategorized.
You can’t flip normals on a closed (solid) object. If you run Dir on a simple surface, do you get the option?
Closed polysurfaces, surfaces, and lightweight extrusion objects cannot have their normal direction facing toward the interior of the object.
