SOME CONSIDERATIONS ABOUT SURFACES’ INTERSECTION

Abstract

This paper wants to systematically and generally present the surfaces’ intersection, with special interest for the method of auxiliary surfaces. The intersections types presented are plane-cylinder, planecone, and cylinder-cylinder. Like auxiliary surfaces will be used, particular planes (level, frontal, profile planes) and sphere surfaces, which every one determine as intersections with the given surfaces, easy to draw straight lines and curves (circles).
