[X3D-Public] CAD Profile screenshots done on Android

[Don Brutzman]

thanks for posting Len.

didn't make it to siggraph this year, but we have a few summaries 
around.  public prose:
http://www.web3d.org/realtime-3d/working-groups/computer-aided-design-cad

i believe that X3D CAD is close to the tip-over cusp of unlocking CAD.
- final updates to X3D v3.3 have gone to ISO
- good support for CAD nodes and 2D nodes (for CADFace) found in 
browsers, almost complete
- we are working on NURBS consistency, and no longer thing we need 
B-REPS (since NURBS are fully general)
- we have a Call for Contributions to improve X3D Compressed Binary 
Encoding, especially looking for geometric compression
- we are steadily building authoring tool support

Our target is to have all of these pieces put together and declare a CAD 
Interactive/Mobile profile by the end of the year.

Lots of detail available at

All feedback welcome, again thanks for asking!
