Scansite Case Study
#78...
Reverse Engineering
a toy plastic teapot
Problems and Opportunities: A plastic toy teapot
was provided by the client. Molds were to be created for
manufacturing toy from plastic.
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 3-D scanning systems (the image shown
is greatly simplified for graphic 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. |
