②Fix each CAD system’s topology difference
①Fix each element’smathematical representation difference
④Fix Geometry Errors
●Edge/Warped Surface/Partial Degeneracy(PDQ)
●Analytical, Bezier, NURBS, polynomial expression●Thinning data●Smoothing●Dividing discontinuous elements
●Presence of seam line●Handling poles●Remove tiny curves under maximum gap
③Fix tolerance difference
●Point/Edge/Face

Elysium Translation
※Simply format translation※No adjustment for target CAD
1. Adjust the tolerance suitable for the targetsystem
2. Heal Geometry/Topology suited for the targetsystem
3. Improve data quality for use all throughout

Customer Information
Business:Design, manufacturing ofaluminum casting moldBusiness Size:$4M sales, 20 employeesUsed CAD:NX
Customer’s Demand
CADdoctor’s Effect
Shortened error fix time on NX
1 week 2 hours
Manual merge ⇒ Auto-Stitch
Redefine faces (trouble) ⇒ Show fixing plan
Expanded Field of Business
Now being able to import and exportraw CATIA V5 data
Began business with major
automobile company
Translation/Healing Case Study
Wanted to shorten error fix timeon NX of IGES data from clients
Wants to install CATIA V5because of clients’ data, but doesnot have the budget to do so
