I'm having some trouble modeling ribs in a project with surfacing tools. I've attached some pictures and a copy of the model that I am working on thus far. Essentially this part is a slice of a sphere made up of a rectangle tube frame with a sheet metal skin. I'm constructing a model to be used for presentation use only, so nothing needs to be detailed for manufacturability, just aesthetically pleasing. I recently have been trainined in surfaces and am trying to find the "light at the end of the tunnel" with this modeling technique. Any help would be greatly appreciated. One more question, does anyone know how to model a pringle? Thanks for any feedback!
