'''CAD Working Group Strategy'''

* Build examples of X3D CAD models to provide use cases and use case and best practices.
* Preserve product structure in CAD node name fields and metadata.
** Resist the urge to refactor CAD product nodes, unless a clear improvement in CAD consistency is shown. Preferred are good practices rather than restrictions that are difficult to enforce.
** Goals
*** Primary goal. CAD definitions converted to X3D geometry, preferring parametric representations for brevity and precision.
*** Secondary goal. Option to save CAD product structure in the use of named X3D CAD product structure nodes, with addition of embedded typed metadata nodes.
*** Third goal. Define, implement, demonstrate and distribute the workflow for converting CAD models to X3D.
* Next steps for activity.
** Compare vocabularies for ISO STEP, Macro Parametric Approach, B-REPS (general definitions) and B-REPS (proposed X3D nodes).
** For each table row, define corresponding mappings to existing parametric X3D nodes (e.g. NURBS, extrusion, primitives).
** Consider implementing these BREPS nodes as NURBS-based X3D prototypes
** These prototypes are an independent implementation that make it easy for either authors or browser to use such BREPS nodes
** Can also update the support for these nodes in Xj3D open source
** List all pros/cons of BREPS nodes as first-class X3D v3.4 nodes
** At this point it is much easier to decide whether to add BREPS to X3D
* Constructive Solid Geometry (CSG) is best considered part of model definition, something that helps to produce BREPS and surfaces, and not something that needs to be supported in browsers and content.
** CSG is computationally heavyweight, and does not belong in a lightweight portrayal format like X3D.
** If browsers are heavy, no one uses them.
** "Lighter, stronger, simpler" is what Hyo hears from his customers.

== X3D CAD Working Group ==

The X3D CAD Working Group is now entering its third generation of development effort.
Following many years of steady progress by Web3D members, we transitioned our efforts to the Web3D Public X3D Wiki in 2011.
Further productive work continues steadily, summarized in the [http://www.web3d.org/realtime-3d/working-groups/computer-aided-design-cad CAD Working Group Executive Summary] and guided by the [[CAD Working Group Strategy]].

Our current activities include:
* Consolidating, reporting and linking past achievements with CAD Geometry Component in X3D
* Continuing implementation of the X3D Compressed Binary Encoding (CBE) for reduced file size and faster loading performance
* Continuing the implementation and evaluation of Boundary Representations (B-REPS) in X3D
* Considering the use of Macro-Parametric Translation for conversion of many CAD formats into X3D
* Building a set of example models to confirm correct operation and encourage the evolution of best practices

Working group co-chairs are:

== X3D CAD Working Group ==

The X3D CAD Working Group is now entering its third generation of development effort.
Following many years of steady progress by Web3D members, we transitioned our efforts to the Web3D Public X3D Wiki in 2011.
Further productive work continues steadily, summarized in the [http://www.web3d.org/realtime-3d/working-groups/computer-aided-design-cad CAD Working Group Executive Summary] and guided by the [[CAD Working Group Strategy]].

Our current activities include:
* Consolidating, reporting and linking past achievements with CAD Geometry Component in X3D
* Continuing implementation of the X3D Compressed Binary Encoding (CBE) for reduced file size and faster loading performance
* Continuing the implementation and evaluation of Boundary Representations (B-REPS) in X3D
* Considering the use of Macro-Parametric Translation for conversion of many CAD formats into X3D
* Building a set of example models to confirm correct operation and encourage the evolution of best practices

Working group co-chairs are:
* Don Brutzman, [http://www.nps.edu Naval Postgraduate School] USA
* Hyokwang Lee, [http://www.kaeri.re.kr:8080/english/ KAERI]/[http://www.web3d.kr Web3D Korea Chapter]/[http://www.partdb.com PartDB]
* Vince Marchetti, [http://kshell.com/pages/scripting/index.html KShell] USA
* Marc Petit, [http://france.edf.com Electricite de France (EDF)]

Please check out the [[X3D CAD People]] page where we summarize our interests.
New participants are welcome.
