This document provides definitions and methods for drawing various engineering curves including involutes, cycloids, spirals, and helices. It defines involutes as the locus of a point on the free end of a string wound around a circular pole. Cycloids are defined as the locus of a point on the edge of a circle rolling along a straight path. Spirals are curves generated by a point revolving around a fixed point while moving toward it. Helices are curves generated by a point moving around the surface of a cylinder or cone while advancing in the axial direction. The document also gives methods for drawing tangents and normals to these curves.
