Here's the wireframe of all three cylinders as requested, Baz. I'm not sure what exactly you mean by *"grouped"*... there's always a bit of confusion when it comes to modeling terms since the syntax varies from application to application. I am guessing that by grouped you mean that the polygons (faces) share points, or are all welded together. If this is what you mean, then yes... I have six "groups" of polygons... and I have pushed them together so that the respective points of their edges share coordinates (co-existing in the same space), but are not merged or welded. No, as you can see in the wireframes... there are no n-gons here. All the polygons are either tri's or quad's. Hope that clears things up more. :o) Cheers! - M
