== 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, 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]
* Marc Petit, [http://france.edf.com Electricite de France (EDF)]

== 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, 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.PartDB.com PartDB] and [http://www.web3d.kr Web3D Korea Chapter]
* Marc Petit, [http://france.edf.com Electricite de France (EDF)]

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

[[X3D CAD]] working group members: please provide short-summary descriptions of your interests in X3D CAD efforts. Thanks!

== Don Brutzman ==

I am interested in unlocking the innumerable proprietary CAD models that the U.S. Navy has purchased over the years, making them accessible and useful to support modeling, simulation, maintenance, training and visualization. I am also interested in using 3D printers to facilitate deployed prototyping or production of critical parts.

== William O. Glascoe III ==

My interests in X3D are three-fold
# Advocate for X3D adoption to bridge the "air gap" between the CAD IP flowing in products' supply chain and the CAD-less consumer chain
# Advocate for X3D adoption in the Military Health System to pilot my idea of Human Health Graphs--a bridge between history of health and health care, present health & health care and planned/scheduled health & healthcare
# Advocate for X3D adoption by the DoD Modeling & Simulation Coordination Office as a key enabler for the DoD enterprise digital asset management

== Hyokwang Lee ==
I'm interested in CAD2X3D conversion and visualization of massive CAD data. I have worked for conversion of CATIA data to X3D with product structure and property information and visualization of them in a web-based system. My current issue is to figure out efficient lightweight representation schemes for CAD geometry and apply them to X3D, hoping that X3D can be a powerful lightwegiht visualization format for CAD data.
* [http://www.PartDB.com PartDB] and [http://www.web3d.kr Web3D Korea Chapter]

== Vince Marchetti ==

I am interested in using X3D as a method to present CAD information from the web for general purpose clients, such as web browsers. In particular, I would like to present 3D models generated from STEP (ISO 10303) data files. I am developing a web application [ http://spri.kshell.com SPRI ] which allows users to upload STEP data files and browse the contents of that file, I would like to enhance the ability to deliver both explicit 3D models and other conceptual information transmitted as X3D.

To further this end, I am also interested in developing the capabilities for browsers to use the NURBS Component of the X3D standard.

== Christophe Mouton ==

== Marc Petit ==

* [http://france.edf.com Electricite de France (EDF)]

My main interest is integration of 3D into the Information System. When industrial installations (like power plants) are concerned, CAD is interesting because it allows :

* Reduced network footprint (higher-level primitives)

* Consistency with the IS (structure, identification of parts)

For CAD, I mostly see X3D as a presentation format. I'd be glad to see it cover interchange too, but presentation can bring high rewards rather fast while staying focused.

== 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.
Further work continues.

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.PartDB.com PartDB] and [http://www.web3d.kr Web3D Korea Chapter]

== 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.
Further work continues.

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.PartDB.com PartDB] and [http://www.web3d.kr Web3D Korea Chapter]

CAD Working Group Strategy

'''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 is 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

a. 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.

b. Resist the urge to refactor CAD product nodes, unless a clear
improvement in CAD consistency is shown. Preferred is good practices
rather than restrictions that are difficult to enforce.

c. 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.

d. 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

e. 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.

Our current activities include:
* Consolidating 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.PartDB.com PartDB] and [http://www.web3d.kr Web3D Korea Chapter]
