InnovMetric announced that PolyWorks|Modeler 2021 introduces a new automatic surfacing technology that produces light NURBS surface models editable in CAD software and a streamlined re-verse-engineering workflow that integrates automatic surfacing within an intuitive curve-based surfacing workflow. In addition to accelerating the creation of models for applications such as milling, high-end 3D visualization, aerodynamic simulation, and mold flow analysis, the PolyWorks|Modeler 2021 next-generation surfacing solution provides CAD designers with ideal patch layouts to initiate a design from a digitized physical object.

PolyWorks|Modeler 2021 proposes an innovative automatic surfacing algorithm that draws characteristic curves over a polygonal surface and partitions the surface into a minimal number of patches:

• Models a polygonal surface with a single click by automating the creation of curves and surface patches and fitting a continuous network of NURBS surfaces
• Creates editable models suitable for CAD design and simulation applications by automatically bounding surface patches with continuous curves that naturally describe the part’s characteristics
• Produces lighter models with better fitting accuracy and patch continuity for downstream applications by automatically adapting the patch size and aspect ratio to the part’s surface curvature

Integrating the automatic surfacing technology within an intuitive curve-based surfacing workflow allows users to get the efficiency benefits of an automated solution while enjoying the flexibility of interactively editing the curve network to create optimal surface models:

• Automatic surfacing results can be edited to remove undesired features by adding, deleting, or reshaping curves, as would be done in a manual reverse-engineering workflow
• The description of curves that are critical for your application, such as symmetry lines, part boundaries, and subtle feature lines, can be controlled by providing predefined curves to the automatic surfacing tool
