・Cannot create NC cutter path

・Geometry Changes

・Cannot add fillet

・Cannot edit

・Much manual labor isneeded

・Unable to Mesh

・Long Calculation Time

・Cannot cut cross section

・Cannot measure centerof round holes and shafts

・Cannot Offset

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

【FYI】Examples of Bad PDQ

Multiple Faces Detached Face

Tiny Elements Intersecting Loops



1. Find Error 2. Zoom Check 3.Choose Fixing

Method 4. Fix Complete

Interactive Healing Function

Does not fix error whichmight ignore the intent of the

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
