Reverse Engineering & Type of Output Data :

- CAD data converted from scan data.

- Can ignore or incorporate manufacturing

defects.

- Parametric solid model (SolidWorks,

Inventor, NX, Creo, Catia…).

- Modify model parametrically.

- CAD data converted from scan data.

- Can ignore or incorporate manufacturing

defects.

- Export IGES (STEP…) surfaces or solid.

- Modifications require re-trimming.

- Captures as-built state.

- Includes manufacturing defects.

- Patch-work of small surfaces.

- Modifications to the file are

going to be made.

- 2D drawings are needed.

- Surface finish must be smooth.

- Few modifications to the file

are going to be made.

- 2D drawings are needed.

- Surface finish must be smooth.

- Designing parts to fit as-built

state.

- Surface finish is not critical.

- Free form shapes (Sculpture… ).
