@Jerome - have been having a play with the arc parameter for the cylinder and I needed to add some sides to get a nice piece of cake. http://www.babylonjs-playground.com/#KSSIF As you can see have added my own. What do you think about the possibility of adding a boolean parameter in the options to say whether this was wanted or not. This would just be for the cylinder as I can see that the sphere, ribbon etc would be much trickier. What do other members think? Name for such an option enclose? Not that you are not busy enough already
