Hello!

I have a highly deformed elongated bubble, and I need to calculate the mean radius along with a bubble.  
For this reason:

1. I extract a surface,

2. take a slice along the bubble (then I have closed curves, the slice can be multiply-connected due to concavities inward)

3. calculate the mean radius of the slice. Here I don’t know how to do it, Any ideas?  
Thank you in advance!
