Polyworks / Modeler is modeling solution that enables a  total interoperability between point cloid digitizing equipment and polygonal modeling (STL), surface modeling (NURBS) and solid modeling workflows.

Among its features are:

Universal platform that supports all high density point cloud digitizers by importing native and neutral file formats and digitizing using plug-ins.
Complete alignment toolbox, including "best-fit "alignment of individual point clouds or multiple scanning sessions and statistical analysis.
World´s best adaptive-meshing technology with distributed processing capability over a computer network.
Total polygon-editing toolbox for correcting imperfectly digitized geometry using flat and curvature-based hole filling, boundary reconstruction, sharp edge and corner reconstruction and more.
Rapid NURBS surfacing capabilities including automatic and interactive curve network creation, support of N-sided patches and T-junctions, automatic NURBS surface fitting with G2/G1/G0 continuity and more.
Advanced interoperability with CAD / CAM applications, including import of IGES / STEP files, watertight tessellation of NURBS surfaces, morphing of tessellated CAD models toward measured models, volumetric or surface-based merging of digitized and tesselated CAD models, local reconstruction of CAD faces using fitted NURBS surfaces and more.
Finite element meshing through the quadrangulation of triangulated models.
