Thanks Olga, I can repeat the problem over here. It will probably take me a little while to figure out why this one works better in v1, one of the fixes to the geometry library in v2 for some other case has made this case not work anymore. Unfortunately that kind of thing can tend to happen when adjusting algorithms for geometric processing.

One thing you can do for now to make this kind of thing easier for MoI to calculate is to extend that line out so that it goes beyond the surface instead of stopping right at the surface boundary.

For instance like this:



That kind of extension will avoid this problem.
