Constructing a simple helix in auto cad

Introduction to helix construction the pitch of a helix helix construction in Auto CAD The helix is the locus of a point that moves around a cylinder at constant velocity while advancing along with the cylinder at constant velocity It is the curve obtained when a piece of string is wound around a cylinder. It is also the curve generated when turning on a lathe. Normally the rate of advance along the piece of work is so small that it is indistinguishable as a helix but it is quite easily seen when cutting a screw thread. The distance that the point moves along the cylinder in one complete revolution is called the pitch.,
