		<h2>Constructor</h2>


		<h3>[name]()</h3>


		<h2>Properties</h2>


		<h3>[property:array holes]</h3>
		<div>
		An array of [page:Path paths] that define the holes in the shape.
		</div>

		<h2>Methods</h2>


		<h3>[method:ShapeGeometry makeGeometry]([page:Object options])</h3>
		<div>
		options -- This is passed as the second argument to [page:ShapeGeometry ShapeGeometry]
		</div>
		<div>
		Convenience method to return ShapeGeometry
		</div>

		<h3>[method:Array extractAllPoints]([page:Integer divisions])</h3>
		<div>
		divisions -- The number of divisions to create on the shape
		</div>
		<div>
		Get points of shape and holes (keypoints based on segments parameter)
		</div>

		<h3>[method:ExtrudeGeometry extrude]([page:Object options])</h3>
		<div>
		options -- This is passed as the second argument to [page:ExtrudeGeometry ExtrudeGeometry]
		</div>
		<div>
		Convenience method to return ExtrudeGeometry
		</div>

		<h3>[method:Object extractPoints]([page:Integer divisions])</h3>
		<div>
		divisions -- The number of divisions to create on the shape
		</div>
		<div>
		Returns an object with a *shape* and *holes* property that each reference an array of [page:Vector2 Vector2s].
