Scansite Case Study # 72
Bell Hellicopter
Reverse Engineering a hellicopter joystick
Problems and Opportunities: A physical model was
provided. A CAD model for import into SolidWorks was
required by the client's contractor.
Downstram Application: An iges128 (Nurbs)
CAD model would be imported into SolidWorks and knit
ito a solid model (a .prt file).
Solution:
 |
 |
 |
| 1.Original Model. This
model was scanned with our proprietary system and a high
density polygon mesh was created. |
2. The polygonized mesh
viewed in our CAD system. |
3. Based on a curvature
analysis, the polygonized mesh was organized into 480 patches
and a nurbs surface was generated. |
 |
 |
|
| 4. The Nurbs surface (iges128)
was interrogated. All grey areas are within .03mm (.001
inches) of the polygonized mesh. |
5. The Nurbs surface rendered
as a solid. |
