Graphics programming for designing conical-helix surface

Abstract

This article analyzes graphical methods for designing conical-helix surface in engineering drawings, presents design system of a surface model and its developments. The creation methods of automated design system of a conicalhelix surface are discovered with graphics programming. Graphical system can design 3D logarithmic spiral with using information of program. Then calculated node coordinates and designed mesh of a conical-helix surface. Graphical system can draw development of surface. Example of a conical-helix surface model and its developments are presented. Creation problems of automated design system are discussed and conclusions are made.
