Surface CAD
 
Generate CAD-friendly freeform surfaces
 
Professional CAD/CAM solutions do not typically offer 3D modeling tools for polygonal models. One common way to transfer the surface of a digitized object into CAD/CAM software consists in fitting a network of NURBS surfaces over a polygonal model built from digitized point clouds. NURBS surfaces are ideal to mathematically describe freeform surfaces, plus they are CAD/CAM friendly.
 
PolyWorks Modeler offers an intuitive surfacing approach in which curves are first laid down on a polygonal model, and then automatically intersected to form four-sided or N-sided trimmed NURBS patches. Next, the NURBS patches are used to control the fitting of a continuous network of NURBS surfaces. Fitted surfaces can then be exported to IGES or STEP files and directly imported into your favourite CAD/CAM application for further processing.
 
PolyWorks Modeler’s NURBS surfacing technology offers a remarkable balance between lead time and surface quality, thanks to:
 
  • Intuitive curve reshaping methods and curvature-continuous curves
  • The best NURBS surface-fitting engine on the reverse-engineering market in terms of quality (accuracy, smoothness, and continuity) and flexibility (trimmed surfaces and T-junctions, curvature-based two-step fitting process, and the possibility of blending fitted surfaces to an existing CAD model for local CAD reconstruction purposes)
  • G2-, G1-, or G0-continuity control over NURBS patch boundaries
  • Automatic G2 surface fitting in areas where NURBS patches have a rectangular topolog
