Hello, Is there any efficient way to compute the resulting cross section area of a closed mesh and a plane (plane, mesh plane, rectangle, plane surf, etc)? Thank you!

No GH model? Here’s a start. Mesh is internalized, no need for .stl file. [mesh_section%20area_2019Nov24a] mesh_section area_2019Nov24a.gh (456.0 KB)

Area from intersection of Mesh and plane

Mesh | Plane? In the ‘Intersect | Mathematical’ tab.

You’ll have better luck if you supply a model with your mesh and plane but this isn’t difficult. You might get curve fragments that must be joined to get a perimeter.
