NX's hybrid modeling includes high-performance tools for feature-based parametric design, as well traditional, explicit modeling and unique direct modeling that works with any geometric model.

With parametric, feature-based CAD modeling, designers can more quickly create solid models by starting with a base shape and applying common mechanical product features like holes, bosses, cutouts, and fillets. The feature-based approach automatically performs the detailed geometric operations to model the component, based on the designer's selection of feature parameter values. Parametric modeling accelerates design modifications by capturing design intent up front, so that changes can be made easily with intuitive, dimension-driven techniques.

Not limited to parametric solid modeling only, NX includes a complete system for explicitly defining wireframe, surface, and solid geometry. These traditional modeling tools enable designers to work with 2D or 3D geometry using a virtually unlimited array of operations, including curve and spline definition; swept, revolved, and lofted solids; Boolean operations for adding, subtracting, and intersecting solid bodies; and precision surface modeling through a network of curves or points. With NX, multiple methods are always available for defining a product's geometric form.

NX also offers unique direct modeling extensions that enable designers to modify models regardless of their source or the techniques used to create them - whether they are native NX parametric, non-parametric, or imported from other CAD systems. By working directly with any model, NX eliminates time wasted on rebuilding or converting geometry. With direct modeling, designers can use parametric features without the limitations of a feature history.
