Software tool to learn the generation of the cardioid curve in autocad environment

Abstract

This article presents a novel application which has been developed in Visual LISP for an AutoCAD environment, and which shows intuitively and quickly the generation of the Cardioid curve in five different ways (conchoid of a circumference, pedal curve of a circumference, inverse of a parabola, orthoptic curve of a circumference and epicycloid of a circumference). This cyclic curve has a large number of artistic and technical applications, among them the profile of some cams.
