Curves & Surfaces
Curves in CAD are crucial for defining complex shapes and forms, represented through various forms like explicit, implicit, and parametric. Key parametric curves include Hermite, Bézier, B-spline, and NURBS, which facilitate effective modeling. Surface modeling techniques extend these concepts into three dimensions, utilizing representations such as parametric surfaces, planar surfaces, and bicubic patches. Applications span product design, engineering, manufacturing, and animation, enhancing precision and creativity in various fields.
