Problems and Opportunities: A plastic orthopedic brace was provided by the client. Molds were to be created for manufacturing.

Downstram Application: An iges128 (Nurbs) CAD model was required. The CAD model will be exported to ProEngineer for mold creation.

Solution: 

1.Original plastic model.	2. The model was scanned in polygon format using our proprietary 3-D scanning systems. (This image is greatly simplified for display purposes)
3. A Nurbs surface (iges128) CAD model was created. The Nurbs surface is "watertight" and all patch boundaries are tangent.	4. The Nurbs surface has been interrogated for fidelity with the polygonized mesh and a color map generated (purple indicates zero deviation).
	5. The iges model converted to a solid. This file is now ready for use in almost any downstream CAD program, including SolidWorks, ProEngineer, Catia, SDRC IDEAS, Solid Edge, Mechanical Desktop, SurfCam, MasterCam, DelCam, etc.
