CENTRAL PROJECTION OF HELIX

Abstract

Acquiring descriptive geometry skills through the curricula of architectural studies can play an important role in preparing students for efficient use of 3 dimensional computer programs. Though nowadays most of the geometric constructions are built-in procedures mainly in 2D CAD programs, users must be able to navigate with 3D models, getting the right projections of them. Architects and construction engineers, whose basic professional communications are drawings, need to use the new medium adroitly. With computers they have to make 'theoretical' decisions rather than to construct exact projections of objects in a traditional way. This article presents a problem in descriptive geometry in order to show the changing role of descriptive geometry teaching for architectural students.
