Does anyone know? It’s like the normals are facing the wrong way but I cant seem to find a way to flip the normals of a NURBS curve, if it’s even possible. :spin:
Nevermind, it’s fixed itself somewhere in the muddle of things I’ve pressed. 
you may have to go into edot mode presse W key and rswitch direction so the normal are flip i guess
it may happen depending on shape
