The **CPlane** command in Rhino sets the construction plane (CPlane) origin and orientation in the active viewport, providing a "tabletop" for drawing. Users can adjust the CPlane's position and rotation using several options such as aligning it with curves, surfaces, objects, and views. Key options include **Curve**, **Object**, **Surface**, **Elevation**, **Rotate**, and **3Point**. For jewelry design, this tool is helpful for setting precise working planes on curves or surfaces for modeling and engraving.
