Abstract

The purpose of this paper is to make the geometric model to the Archimedean spiral, curve often used in practice. Although it is a widely used, in AutoCAD there is no command with which to represent the Archimedean spiral. The method used for determining the mathematical relationships that define the spiral is the coordinate transformation, and for the calculation of the points which define it, is use AutoLISP, representation being made in AutoCAD. The result of this work is to develop an AutoLISP program which can represent the Archimedean spiral, presented a method that can be applied to the representation of any curves used in the technique.
