SOFTWARE TOOL FOR LEARNING THE GENERATION OF THE CARDIOID CURVE IN AN AUTOCAD ENVIRONMENT

摘要

This article presents a novel application which has been developed in Visual LISP for an AutoCAD environment, and which shows the generation of the cardioid curve intuitively and quickly in five different ways (using the 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.
