Curves with equations (EQT) are widely used to create surfaces of machine parts in machine manufacture. They make beautiful surfaces that appeal to consumers. Helix and spiral curves are very popular applications in mechanical engineering and architecture. They not only are the basis for creating threaded surfaces on machine parts but also create beautiful spiral staircases. Based on the results of the 2019 paper, this paper shows how to make the equation of the hyperboloidal helicoidal surface and some projections of hyperboloit helix.
