PolyWorks|Modeler™ is a comprehensive reverse-engineering software solution designed to extract optimal CAD entities—such as curves, surfaces, parametric sketches, and prismatic features—from polygonal models of digitized parts. This facilitates seamless integration with professional CAD modeling applications, serving as an ideal starting point for detailed design and manufacturing processes. Key Features and Functionality: - Polygonal Modeling: Transforms digitized point clouds into accurate, surface-based polygonal models that are compact and suitable for industrial applications like milling, 3D printing, and aerodynamic simulations. - Real-Time Quality Meshing: Enables the creation of polygonal models in real time, ensuring quality and precision during the scanning process. - Geometry Repair and Optimization: Offers tools to fill holes, smooth and rebuild surfaces, clean boundaries, recover sharp edges, and create watertight models from imperfectly digitized data. - CAD Operations on Polygonal Models: Allows users to perform operations such as extruding boundaries, offsetting surfaces, reconstructing fillets, and executing Boolean operations directly on polygonal models. - Surface Modeling with NURBS: Provides an intuitive workflow that combines interactive curve creation with advanced automatic surfacing technology to generate editable, CAD-friendly NURBS surfaces suitable for simulation, machining, and design applications. - Parametric Sketching: Facilitates the creation of parametric 2D sketches by defining sketch planes, computing optimal sketch outlines from digitized geometry, and fitting sketch entities and dimensions guided by the sketch outline. Primary Value and User Solutions: PolyWorks|Modeler™ addresses the challenge of converting complex, digitized 3D data into precise, editable CAD models. By offering a suite of tools for polygonal modeling, surface modeling, and parametric sketching, it streamlines the reverse-engineering process, reducing the time and effort required to create accurate CAD representations of physical parts. This enhances interoperability between digitized models and CAD/CAM applications, enabling users to efficiently transition from physical prototypes to digital designs, thereby accelerating product development cycles and improving manufacturing precision.
