Here is a comparison of MOI v5 with RHINO
MOI v5 the volume is not correct

Hi Brian, can you please post the .3dm model file or e-mail it to me at moi@moi3d.com ?

Hi Brian, looks like a bug. Here is a version that keeps the lines and arcs separate and that seems to work better.

and what exactly are the problems? because such an incorrect calculation occurs quite often

Hi Brian, I'm still examining the cause but it looks like a bug in the geometry library's integration mechanism.

If you have other volume calculation cases that fail please send the .3dm files for them to me at moi@moi3d.com so I can see if they are the same problem or if they're different problems.
