Hi Luca, yes this one behaves a bit differently than a regular command, it does not support the regular kind of canceling mechanism, and while it is busy calculating MoI will appear frozen instead of staying alive like normal.

It should be possible for me to improve this in the future, but for V1 this script will have this problem.

Also you can create a pretty complex calculation with this if you have a lot of curves, or a really long curve, so you probably should only try something complex on this particular one if you have a somewhat faster machine, since it cannot be canceled easily.
