X3D-BREP Draft specification

The following two links are working drafts that were never completed.

• First version of the draft specification: http://web3d.org/membership/login/groups/CAD/X3D-BREP/CADGeometry_20090316.html
• Second version of the draft specification: http://web3d.org/membership/login/groups/CAD/X3D-BREP/CADGeometry_20090909.html
• TODO: minimal changes to restore image links, add titles and dates at top so that these are printable and legible

The renewed CAD Working Group is evaluating the completeness, correctness and usefulness of this draft specification. If it is eventually and verified to be fully worthwhile, then this work will be proposed as part of the future X3D v3.4 specification.
