Min and Max Principal Curvature

Hello, I am trying to understand the Principal Curvature function. I followed the example in The Essential Mathematics For Computational Design for cylindrical surface:

I modeled similar and was expecting Min values to be ‘0’ too, but instead it returned zeros for Max values.
Did anyone had this problem? Or am I making something wrong?


Hi Anna, I am having the same issue. Did you figure it out yet?
