1. Create surface with 3 curves.
2. Deconstruct and reconstruct the domain of the surface with Graph Mapper and List to create a newly divided subsurface.
3. Extract control points and connect them according to information extracted from the simplified branches of the data tree.
4. Use Prune Tree to further simplify by removing small branches from data tree and connect the dots with Interpolate to create curves. Extrude curves according to Z direction to create the final result.
