Extrudes a 2D polygon shape to create a 3D mesh.

.. rst-class:: classref-introduction-group

Description
-----------

An array of 2D points is extruded to quickly and easily create a variety of 3D meshes. See also :ref:`CSGMesh3D<class_CSGMesh3D>` for using 3D meshes as CSG nodes.

\ **Note:** CSG nodes are intended to be used for level prototyping. Creating CSG nodes has a significant CPU cost compared to creating a :ref:`MeshInstance3D<class_MeshInstance3D>` with a :ref:`PrimitiveMesh<class_PrimitiveMesh>`. Moving a CSG node within another CSG node also has a significant CPU cost, so it should be avoided during gameplay.
