NX Law Curves

A law curve is a special type of curve generated by defining mathematical relationships, or “laws,” that control the shape of the curve along its length. These laws can vary parameters such as radius, angle, or position, allowing for highly controlled, complex curves that change dynamically according to specified rules.

Law curves are typically used in advanced modeling scenarios, especially when designing parts with varying cross-sections, creating lofts or sweeps where the profile needs to evolve in a specific manner, or defining precise transitions in surfaces. They allow for parametric control over the geometry and offer a powerful tool for maintaining design intent in situations where standard curves wouldn’t suffice.

These curves can be influenced by mathematical functions or expressions, providing flexibility in shaping the model to meet complex design requirements.
