This paper presents a design approach shows the usefulness of the software in the management of parameters in the design of products. Indeed, until now, the definition of this type of interface depends only on knowledge of the designers. It was therefore difficult to group settings to facilitate modular design. To highlight this, the methodology presented in this paper is to describe a journey through various design software to reduce the designers’ work. Rules that the designer has put in place during the design of the product, called ”design rules” also define the interface. This has the advantage to guide the designer in his work and to allow a rapid evolution of the interface in the case of product development. The objective is to reduce the time of the routine engineering to devote more time to innovation. At the same time, this method allows you to define assembly sequences based on parameters needed to design the product. Some calculations to be carried out before others because the calculated parameters are necessary in one to another. The definition of an ordered graph allows to directly obtain valid assembly sequences necessary for design while offering designers a thread.
