In this paper, we make the assumption that a shape modelling process can rely on the application of a set of morpho-semantic operators to initial shapes. In this paper, we will refer to several researches which have attempted to identify such operators.
We will attempt to validate this concept through the analysis of some "innovative"buildings. Thus, in different projects of contemporary architects, we can find the trace of some transformations (e.g. "twist", "merge", "overlay", etc.) recorded in the final geometry. These transformations have a symbolic representation. A design system based on the combination of these operators could enable the designer to quickly explore a great number of spatial solutions.
