Hi Michael, and thanks. I needed perpendicular edges (at least I think thats the right terms in english). Like this:



Actually half the model looks like the one below, but I couldn't shell it, so I tried dividing in three parts, which then would have to have perpendicular edges so I could join them together again. But as I said, thats only half of the model, the whole model is the one I recently posted a photo of in plywood.



It's bedtime here in Sweden, but I will have a closer look at your examples tomorrow. Thanks again.
