STUDY ON THE PROJECTION WITH ELEVATIONS OF HELICOID-TYPE SURFACES

Abstract

This paper presents right helicoid surfaces in various systems of representation. Emphasis was put on the representation of helicoid surfaces in the projection with elevations, where both the right helicoid with a perpendicular axis on the elevated plan and the right helicoid with the axis inclined at a certain angle to the elevated plan.
