Select Surface same plane of a curve

Hi there,

I am looking for a solution to automatically select the surface that is on the same plane of the selected curve.
Otherway; I would like to select a closed curve, then the script would identify the surface that is located on the same plane as the closed curve.

EDIT: I have found BoxSelection reasonable, however it is complicated.



I haven’t tried this script but it sounds like it is what you want.



Should work if the surface is a single surface, but it won’t if it’s part of a polysurface.
