Create smooth curves that run along a face or surface in the U or V direction.

Similar to a weave of cloth, every surface is roughly rectangular. Surfaces have three directions: U, V, and Normal. The Boundary surface profiles U and V represent the X and Y directions of the surface, respectively.

Isoparametric curve created along a smooth surface

Use these curves with other features. For example, you can split the face using the curves. Then, use the Delete Face feature to remove the center portion. Once removed, you can add a ruled surface, 3D Fit splines, and Loft.
