Who is Kubotek?
• Purchased all of the assets of Cadkey Corporation in 2002
• 20+ years in CAD/CAM, 6,000+ customers, 20,000+ seats
• Promoter of open CAD formats and “Direct Modeling”
• History of innovation and tapping intelligence imbedded in geometry– Feature Discovery– Prune and Graft– Pattern Recognition
• Different Approach to Validation
Technology FoundationFace LogicOpen 3D environment
Pattern Discovery Applied to Validation
• For comparison of Neutral and Native OEM supplier data sets
• Helps to insure that CAD files translate properly into different software
• To compare revisions (EO’s) of two different designs
• Support of STEP, IGES, Catia V4, V5, UG, Pro/E, SolidWorks, Inventor, KeyCreator, STEP, IGES, ParaSolid, ACIS, Points, STL, Adobe U3D
Where Does the Technology Fit?
1. Comparing Authority Models to Supplier Translations and Point Sets
2. Comparing Design Changes (EO’s)
Typical OEM Supplier Scenarios
• Check faces in Copy file to faces in Master file
• Check inspection point nominals in Copy file to Master file
• Check to see if all faces in Master file have inspection points in copy file associated to them
