Software Feature Recognition Restores Lost CAD Surface Data

The latest release of Polygonica from MachineWorks includes functionality for automatic feature recognition on polygonal solids.

The latest release of Polygonica from MachineWorks includes functionality for automatic feature recognition on polygonal solids. The software is capable of regenerating original surface information from triangulated data, even on CAD models that have lost original surface data after being tessellated into a mesh. The feature detection algorithm takes in the mesh information and automatically returns the surface data of the feature as well as surface area, bounding box and error values. Geometric features detected include planes, spheres, cones, cylinder and torii. Boundaries around features can also be determined and queried, enabling the application to tell which features are adjacent to others. Polygonica feature detection can quickly and accurately determine a set of geometric features, providing a crucial first step in many tasks such as reverse engineering, remeshing and automation, the company says.
