Abstract

From the point to the hyperbolic paraboloid: 3D CAD for teaching and profession L.F. Meyer, H. Feliciangeli, C.F. Meyer Department of Applied Engineering, School of Engineering, National University of Asuncion, P.O. Box 765, Asuncion, Paraguay ABSTRACT This paper presents a macro package that deals with geometric entities to be used either for teaching of Descriptive Geometry or as a professional tool mainly for engineers and architects who work with hyperbolic paraboloid structures, both at the design and at the construction phases. For all cases, visual representation may always be stereoscopic (3-D image with the help of bicolor filters) , using an incorporated algorithm developed previously by one of the Authors. The package (a library of macros designated AutoVEC), written in AutoLISP, internally uses vector analysis to handle geometric entities. The entire presentation is in AutoCAD Menu Format a
