Very nice.
But why use square meters instead of the "unit system" specified in Moi's options?
I model using millimeters, and your function gives me values ​​like 0.00 m².
Moi's detail function also provides the area.
You just need to take the curve, create a plane of it, and then request the area detail.

Your script allows you to get the area more quickly, but I think keeping the "unit system" would be preferable.

Thanks
