What is required to create a Bounded Plane?

To create a Bounded Plane in Siemens NX, a closed set of 2D curves is necessary. This is because a Bounded Plane represents a flat surface that is defined within a specific boundary. The closed set of 2D curves acts as the perimeter that encloses a defined area in the 2-dimensional space.

When these curves are closed, they establish a finite region that can be filled or used as a surface. This is crucial in CAD design, where the geometry created needs to have defined limits for further operations, such as applying features or generating solids. Open curves, whether in 2D or 3D, do not create bounded areas and therefore cannot define a plane or surface in this context.

In summary, the requirement for a closed set of 2D curves is essential as it provides the necessary boundary for creating a Bounded Plane, facilitating precise design and modeling in Siemens NX.
