I can't wait :)

So : my first method :

I have a question :
Why can't I use "Proj" intersection beetween main outline curve and solid at step2 to get separate volumes?
It only creates some points on the solid...that's why i use the "ugly" extrusion method at stpe3....

Not really good method to my opinion, but it works....

Sorry for the bad english...
