attached, please find a Rhino File of two closed volumes. One of them is completely inside of the other one.
I tried to create a Boolean difference, in order to create a “hollow” Box, but that didn’t work.
I need to do this in Order to calculate the volume correctly. (Not add the volumes, but subtract them from each other).
Is that generally possible?
Or more generally, how does Rhino handle hollow boxes with a “wall thickness”?
