One of the elements of designing complex technical systems is the problem of their various aspects of designing and modelling. In the field of design, the issues of both system design and material design should be considered which aspects would fit the given function of the given system. Each complex mechatronic system is defined as a combination of three component subsystems, namely a mechanical system, a control system and software. In this context, it is important to create a mechatronic function of such a complex technical means using tools that allow it to be modelled. In the article is presented a method of integrative approach as well as its formalization in the form of integration of different construction characteristics that should be optimized. The paper includes the example of its application for developing the construction of this support. The support is a special design of a mining machine intended to support the roof over that area of hard coal mining. In the paper is also described the results of the characteristics analysis and changings that were introduced afterwards. The support models are prepared in the computer environment of the CAD class. Also the analyses were conducted in this design, graphical environment.
