This article explains how to use Mesh｜Plane to obtain the intersection curve between a mesh and a plane.
On the Grasshopper, it is represented by either of the two above.
Extracting a curve where a mesh intersects a plane or a plane surface
Mesh｜Plane can be used to extract a curve where a mesh intersects a plane or a plane surface.
Mesh to be used this time
In this tutorial, we will use the mesh above.
Basic usage of Mesh｜Plane
Components used: (1) Mesh (2) XY Plane (3) Mesh｜Plane
This is the basic usage of Mesh｜Plane.
Connect a mesh to Mesh｜Plane(M).
Connect a plane or a plane surface to Mesh｜Plane(P).
In this case, we will use XY Plane to create a plane.
The curve at the intersection of the mesh and the plane can now be extracted.
Can be performed on a surface instead of a plane
Components used: (1) Mesh ( 2 ) Surface (3) Mesh｜Plane
The extraction can be performed not only on a plane but also on a plane surface.
In this case, a surface set in Surface is connected to Mesh｜Plane(P).
Then the curve where the mesh and surface intersect are extracted.
