Peculiarities of geometrical drawing in contemporary engineering graphics

Abstract

So far computer educational engineering graphics has been using not all its possibilities , because it is based on obsolete visualization methods. Formation of a new conception and technology is based on two conditions: (1) the requirements and tasks have changed in computing, so the studying of traditional methods became useless, because those methods are not used in real life; (2) the possibilities of graphics have also changed. The automatic analysis of computer drawing is possible nowadays, that was impossible using traditional technologies. Besides, additional engineering information can be attached to computer drawing. Consequently, graphical content gains essentially new informative possibilities. The new outlook of graphics should be rebuilt injustice to positive aspects of traditional things and new possibilities of information technologies. This task can be solved by modelling information engineering graphics (IEG) and all its component parts. In VGTU an IEG model is evolved, which include a common and a special part. The common IEG part includes information geometric drawing, surface and volumetric modelling, interactive and automatic generation and/or modelling of projections and information building drawing fundamentals. The models of information geometrical drawing are presented in this paper. Those models are the foundation of2D graphics.
