Computer Aided Design (CAD) aids in the creation, modification, analysis, or optimization of model design, with specialized support provided by the X3D CADGeometry component.

	The Computer Aided Design (CAD) examples illustrate simple concepts provided by the X3D CAD Geometry Component and CADInterchange Profile. Significant additional work is being pursued by the X3D CAD Working Group and is documented on the X3D CAD Working Group Wiki.
	A supporting CAD chapter slideset is available online via X3dGraphics.com. Technical capabilities are summarized by the SC-4 TC-184 Visualization Requirements For X3D CAD report, published May 2009.
