【 摘 要 】

Computer modeling of polyhedral surfaces is one of the most complex and interesting areas of architectural shaping. Computer-aided design systems, such as MathCad, Mathematika, AutoCad, etc., allow solving various problems on the formation of surfaces. The AutoCad system has significant advantages, because it has a built-in functional language AutoLisp, which has functions for mathematical calculations and for drawing different objects in 3D space. In this paper, a method of forming the surfaces of regular polyhedra in an AutoCAD environment through the use of programs in the language of Autolisp is considered.To demonstrate the method, a dodecahedron (Plato's body), a large dodecahedron and a small star dodecahedron (Kepler-Poinsot bodies) are selected.
