||The digital graphic systems development is evident during the alternative generation process, especially when the component objects are linked to a geometric base by modulation. In this sense, the tiling modular characteristics are used as geometric support which modulation or internal divisions contain material forms (objects in 3D) immaterial forms (spaces in 3D). That is to say that each tiling module can be projected or not in 3D. The way to do this consists of applying it not only as two-dimensional support but also as operational structure by means of operations of pure translation, in 3D. It is applied to architectural themes which systemic parts or components sectors admit repetitions of units (dwelling buildings, schools, offices, hotels, etc.) in plan floor levels and in elevation as well. When programmatic and morphological requirements are solved groups are organized conforming systems in two or three dimensions. In the alternative generation stage it is tried to avoid conditioning and restrictions developing a ludic process of "piling up tiles" simple concepts stimulating creativity for the production of innovating architectonic forms. Creative ideas can arise from the game playing with 3D forms. This paper attempts to show a manner to generate unusual architectural forms that, otherwise, within a traditional design process might not be found. Some architectural examples developed with this ludic procedure are presented.
