Here is an image that I quickly did. I also learned that "object edge" settings draws a Line around the object outline or silhouete, while "hard edge" draws lines for the interior edges. Use "1" for both of these. To get "Toon lines" on interior flat surfaces, they have to be separate meshes. So you have to be aware of this when modelling , then do a split object command to make individual meshes. Regards Mike
