Conics and quadrics are classic topics at Engineering Schools. Conics are usually introduced from constructive properties and their equations and classification are presented later. Meanwhile, quadrics are introduced directly from their equations. The availability of 3D dynamic geometry systems allows introducing the quadrics of revolution (degenerate and non‐degenerate) in a constructive way too. How the approach can be used to obtain the equations of one parameter families of quadrics will be also shown. © 2016 Wiley Periodicals, Inc.
