Hello Marv,

I had a little time to use your curves as guides and here is what I came up with. It's not perfect, the Blends are not exactly right, but I was intent on staying in MoI for all operations except the render. Typically you'll need some other modeling tools in order to make surfacing for things like planes easier for you, but I'm confident those sort of advanced surfacing tools will eventually make it into MoI. If you'd like to see a tutorial I can see what I can do.
