Hello guys,

I`m trying to call a function in RHINO5 called ‘MeshSplit’ into GH Python.
Imported Libraries:
Rhino,
RhinoScriptSyntax

However when I use function “r.Geometry.Mesh.Split()”, the fucntions avaible are only by Mesh and Mesh, Mesh and Plane. pls see pic below

But In RHION5, the mesh could be splited by curve. pls see the pic below.

Native Rhino commands and Methods in scripting are often different… don’t be confused by similar names. For example here you can find methods you can use for meshes:
http://developer.rhino3d.com/api/RhinoCommon/html/T_Rhino_Geometry_Mesh.htm

What Rhino probably does behind the scenes, is extrude the curve through the boundary box of the mesh, then mesh the result and do a Mesh/Mesh split operation. So this is the way you could replicate it in a script.
