Thank-you Michael.

MOI is amazing. Inspirational. Intuitive and easy to use. The first thing that caught my eye towards using this great Software was how simple it was to swap and design through split views. It is becoming easier to navigate.

You have answered my question;

(self intersecting solids, the "skin" of a solid will tend to cause volume oriented calculations like booleans to fail)

Is there a way to skin such an object or cover just the outside of the object, lending a way to achieve the cross-section?

Script perhaps?

Thank-you
Dave
