Hi Pilou

Thank you for liking the image; it took me a lot of work to get it, thanks to the help I received.

Regarding the curves, I know they're the same. Curve "A" is the one 777RAVEN777 suggested, and "B" is taken from the outline of 777RAVEN777's extruded image; I didn't draw it myself, which is why there's a difference. If your explanation also serves the same purpose, then that's fine with me.

Thanks.
