CAD WG Minutes

• TC184/SC4 Issues : JT as a CAD standard from ISO TC184/SC4
  • Web3D is asking ISO/IEC JTC1/SC24 what are the ISO procedures and rules for patents in ISO standards.
  • We might invite TC184/SC4 to brief JTC1/SC24 and X3D CAD Working Group on their new standard.
    • Dick please find/add link to relevant ISO standards documents
    • Does this standard include patents and licensing fees?
  • see press release: http://www.plm.automation.siemens.com/en_us/about_us/newsroom/press/press_release.cfm?Component=205727&ComponentTemplate=822
    • "Siemens’ JT Data Format Accepted as the World’s First ISO International Standard for Viewing and Sharing Lightweight 3D Product Information"
    • Don has sent them email asking for a conference about this erroneous and misleading statement.
    • Shouldn't SC 24 also be concerned?
  • What is the precise status of JT as a specification?
    • ISO 14306:2012 : http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=60572
  • Does Han SoonHung have any advice for us, I believe that he is our liaison to SC4/TC184
  • What should we do next?

• NURBS code integration in Xj3D NPS branch
  • A working example, which can now be rendered from the NPS branch of Xj3D: http://spri2.kshell.com/xt/shape/sc4t2b2ry8hh/shape_2331363031.x3d . This was converted from a STEP file downloaded from the Elkhart Brass Co ( http://www.elkhartbrass.com/downloads/models ), makers of fire-fighting equipment.
  • Vince is providing changes to Don, we are testing Xj3D source NPS branch, when done we will upgrade primary Xj3D trunk
  • When we finish testing Xj3D on the X3D NURBS examples, NPS will work with Xj3D source list to update Xj3D trunk, we will conduct further testing on the x3d-public mailing list
• X3DOM integration
  • Hyo has been working on X3DOM source
