+				Returns mesh arrays used to constitute surface of [Mesh]. The result can be passed to [method ArrayMesh.add_surface_from_arrays] to create a new surface. For example:
+				[codeblock]
+				var c := CylinderMesh.new()
+				var arr_mesh := ArrayMesh.new()
+				arr_mesh.add_surface_from_arrays(Mesh.PRIMITIVE_TRIANGLES, c.get_mesh_arrays())
