“…A lot of methods have been used to solve this problem: algebraic approaches, often based on the Newton-Raphson iterative method [5] [6] [7], inference engine [4] [8], Buchberger's Gröbner Bases Method [9] [10], constraint graphs [11] [12], and many others [13]. The popular 2D "sketcher", available on various CAD systems, corresponds to this approach.…”

This paper investigates the problem of parametrics within the perspective of generating and exchanging families of cognate products. Two ways are discussed. A parametric representation gathers together within the same structure the parametric definition and one specific instance: the current instance. An EXPRESS model that follows this approach is presented. Its integration within the STEP Standard would enable the exchange of (simple) parametric designs. The use of a parametric program, based on a standard API, is a more conventional approach. We present the EBP system which enables such a program to be generated through purely graphical interactions. This system provides for all the constructs required in the target program: variables, expressions, functions, and control structures. If the API itself supports all these constructs, the parametric representation may be restored on the receiving system.
