Power Surfacing, says nPower, unites the disparate modeling paradigms of Sub-D (subdivision surface) modeling and NURBS-based CAD modeling. Sub-D modeling excels at producing and modifying complex, freeform organic shapes with smooth surfaces, explains the company, while NURBS modeling is good at combining shapes using Boolean and feature operations, as well as refining shapes with operations like filleting, blending, and face editing. Being able to use both modeling paradigms together in the modeling process provides huge productivity advantages in both the design and revision processes, says the company.

Creating and manipulating Power Surfacing parts is described as being as simple as modeling with clay. Power Surfacing, the company explains further, allows great flexibility and productivity in designing difficult surfaces because it enables users to push and pull on the faces, edges, or vertices of a part. Shapes are created as single unified objects that can be modified easily without pulling apart the resulting NURBS surfaces.

nPower says that users create their initial Power Surfacing objects inside of SolidWorks using a sketch as a reference. The company adds further that the users then design their shape with Power Surfacing tools inside of the SolidWorks environment. Once a user converts a Power Surfacing design into a native SolidWorks part, their Sub-D models are treated as if they had been created with traditional SolidWorks tools, according to nPower. This attribute also means that users can apply such SolidWorks features as holes, bosses, fillets, and shells to the part as if it had been modeled using SolidWorks.

After applying SolidWorks features, Power Surfacing users can return to the original Sub-D form and modify the surface shape and downstream features will be reapplied. Additionally, the solution can quickly and accurately convert virtually any Sub-D model (even Sub-D models that have some triangles) into the precise NURBS representation that is standard for SolidWorks parts, according to the company. Power Surfacing can also be used to import Sub-D models from products such as Maya, Modo, 3DS Max, Z-Brush, and Blender.
