Surface No Orientable

This Python package implements a modular framework for constructing and visualizing non-orientable surfaces using NURBS. The surfaces are generated from generating curves and directrices (usually the circumference) defined by control points, weights, and nodes, modeling the geometry as a curve that rotates, turns, and moves around another. The main module (NonOrientableSurfaces.py) can be easily reused in external projects, providing a flexible foundation for research and educational applications in computational geometry.
