CSGPolygon3D
============

**Inherits:** :ref:`CSGPrimitive3D<class_CSGPrimitive3D>` **<** :ref:`CSGShape3D<class_CSGShape3D>` **<** :ref:`GeometryInstance3D<class_GeometryInstance3D>` **<** :ref:`VisualInstance3D<class_VisualInstance3D>` **<** :ref:`Node3D<class_Node3D>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

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

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.
