The Subdivide operator divides selected surface segments by adding control points, effectively increasing the segment resolution. This is useful for refining shapes, creating smoother transitions, or adding detail to surfaces.

For 2D surface grids, this operation splits selected grids into four smaller grids, increasing the density of control points. For 1D surfaces (also referred to as "surface curves"), the operator behaves the same as it does with curves.

The Switch Direction operator reverses the direction of the selected surface segments. The start point of the curve becomes the end point, and vice versa.

Reversing the direction of surface segments flips their "normals". Normals determine the "front" and "back" faces of the surface and are essential for proper shading, lighting, and rendering.
