You either have to be consistent in the ordering of the lines in ALL of your Line Loops – or you can flip the ordering for the ones causing troubles. This example program shows some of ways to create and modify meshes for. The ordering of the lines in Line Loop affects what normal is going to be used in the Surface created from this Line Loop. Any idea how can I make it right (or the way I need it to be)? Since I also define a volume, all the normal vectors are supposed to point OUTWARD.
