Merci Beaucoup Pilou!

I'm going to try this now. I'll let you know how it goes.

Fellows,

I'm in the process of redesigning a concrete structure for the greater good. It's called the Villager model and I intend to mass produce them in impoverished areas of the world, beginning in West Africa along the Congo River.

The structure is circular, 20 ft across from the outer walls. The base is made up of three arches which elevate it off the ground. I started with a circle made up of 30 segments. Next I broke it into thirds. I then copied the outer arc from one of the thirds. The length of the arc is 20' 11 5/16". Next I drew the shape that I plan to bend the same length as the arc ( 20' 11 5/16"). I go through the CLF Shape bender steps and the result is very close to what I need. The problem I'm having is the faces on the inner wall of the curved arch are all triangulated. I notice when I perform the CLF steps on just a rectangle, the faces on the inner walls are not triangulated. So the problem is being caused by the arch. There are 50 segments in the arch pictured. I tried drawing it with 12 segments and the triangulation on the inner curved faces was less, but still unacceptable. I need these faces to be flat and extrudable so i'll be able to draw the formwork panels that will be used to pour the structure. I've attached a picture of my original Villager model and another sketch showing the problem I'm having with the new one. Any advice would be greatly appreciated.

Thank you,
Eric
