Reverse engineering using 3D scan data is the most efficient way to generate a CAD model from a physical object that has any kind of complex or free form shape. While using traditional measurement techniques such as calipers to reverse engineer these complex surfaces can be difficult or even impossible, 3D laser scanning shines – literally! Although this scan data can easily be turned into a model representing its as-built shape (a shrinkwrap model), we specialize in creating models that match original as-designed features – even parametric ones.
REVERSE ENGINEERING MODEL TYPES
Our reverse engineering process outputs files in 3 major categories. However, every client’s file is further customized to meet their exact requirements, as every project is different.
PARAMETRIC MODEL
CHARACTERISTICS
- Ideal data converted from scan data
Can ignore or incorporate manufacturing defects
Parametric solid model
Modify model parametrically
Can be Class A surfaced
WHEN TO USE
- Modifications to the file are going to be made
2D drawings are needed
Surface finish must be smooth (for manufacturing)
Buildings parts on or around scanned part
HYBRID SURFACE MODEL
CHARACTERISTICS
- Ideal data converted from scan data
- Can ignore or incorporate manufacturing defects
- “Dumb” IGES surfaces or solid
- Modifications require re-trimming
- Can be Class A surfaced
WHEN TO USE
- Few modifications to the file are going to be made
- 2D drawings are needed
- Surface finish must be smooth (for manufacturing)
- Buildings parts on or around scanned part
SHRINKWRAP SURFACE MODEL
CHARACTERISTICS
- Captures as-built state
- Includes manufacturing defects
- Patch-work of small surfaces
- Non Class A surface finish
WHEN TO USE
- Need as-built state
- Designing parts to fit as-built state
- Surface finish is not critical
- Free form shapes such as teeth, bones, sculptures, and custom-fit molds
