ON DEMAND IDENTIFIER AND GEOMETRY PIECE ASSOCIATION IN COMPUTER AIDED DESIGN (CAD) ENVIRONMENT

The invention includes computer instructions that operate to receive an indication of an association between an identifier and a geometry piece of a mechanical design. The association is stored in response to the received indication. The instructions further operate to determine if at least one of the identifier and the geometry piece is selected. Upon determining that at least one of the identifier and the geometry piece is selected, the instructions operate to automatically generate and display a leader between the geometry piece and the identifier to visually denote the association between the identifier and the geometry piece. As a result, an improved way of generating and maintaining associations between identifiers and geometry pieces of a mechanical design, including automatic modification of leader termination on the mechanical design, is facilitated.
