Selected forms of graphic and analytical presentation were discussed for multiplelevel explosions of material structure of complex products. In order to characterise the product structure a method was proposed to identify the degree of its complexity and the number of the structure level, using which the position of components is identified in graphic presentations. Four forms of graphic presentation were distinguished and identified for the product structure, i.e. imploded, exploded, vertical and horizontal. Algorithms for their development are proposed in this paper. Examples of furniture items were used to illustrate the discussed problems.
