I have recoded my application to use two large cuboid prisms instead of half spaces this returns the correct result demonstrating that multiple half spaces is the problem. The file Correct uploaded is how the result should be returned.

Reminder sent to: jgv

Can I confirm this is still a major problem, cutting more than one half space at a time from a solid produces incorrect results
