Feature Line Extraction
Sharp edge extraction from unstructured point cloud  
The most critical part in reverse engineering is the segmentation of digital point clouds, where data points are grouped into sets to which an appropriate single surface can be fitted. For the modeling of freeform geometry, four-sided surface patches with NURBS representation are commonly used. In order to get a compound of smooth surface patches, the patch boundaries must be located along edges of the measured part.

The software module Feature Lines offers the possibility to extract feature lines from point clouds, essential for the creation of a network of boundary curves.
