Introduction

The best way to introduce drawing to engineers is to quote from Borges words on Geometry as follows

The line is made up of an infinite number of points; the plane of an
infinite number of lines; the volume of an infinite number of planes; the hypervolume of an infinite number of volumes.... No, unquestionably this is not - more geometric- the best way of beginning my story.
