GeometryMath Clip

Workflows
1

Hi,

Please could an example of using GeometryMath.Clip be shared.

Specifically, I’d like to clip a linestring, to within a Buffer() from point, then find the Centroid() of that clipped geometry. I’d be happy for just Clip to be discussed here to keep it simple.

Thank You
