  This note presents the definition of a proposed generalization of the
conchoid at the plane. Known conchoids, such as the Nicomedes and the
Lima\c{c}on of Pascal are part of this set. Following the definition, one can
generate other conchoids. Examples are generated using of a computer code that
is available openly for download. In addition, two step-by-step examples are
described by detail, the first one which presents the results in calculation
tables.
