✦ Synopsis

A parametric program may use rules and algorithms to define the relationships between dimensions and elements of designs, and it may thus generate variants of a design. Programs currently in use have technical limitations in their ability to handle time-varying and imprecise data, the search for suitable existing designs and their maintainability. The paper suggests how these and other limitations can be overcome to widen the field of application of parametric programs. design automation, variant design, parametric programming, parametric methods

The aim of this paper is to present guidelines for the application and development of parametric methods for design automation in computer-aided design (CAD). The guidelines are based on observations made in the course of carrying out projects investigating the automation of the preliminary design of automotive products. The design of the products in question is based on the customization of a standard design, which incorporates essentially standard elements, to customer requirements.

The parametric approach involves complete or partial automation of the production of drawings, geometric models and other aspects of design data for certain classes of (principally) mechanical designs involving variation
