I just needed to try one more thing, I did, and it works like charm! Matlab is awesome! Thanks for you blog!! It was the key! Hey, never mind!

Now I want to calculate the surface area of that inner structure ONLY. Is that possible, and how do i go about finding it. Thanks a lot Hi Steve, Thanks for all your previous inputs. i have another problem. i have a volume similar to as shown in this link.
