Mediation in architectural drawing and its teaching, and in general in art and didactics, is a phenomenon that occurs constantly but with different intensity and at different periods of time. Then, the meta- prefix appears and we obtain ‘meta-art’, ‘meta-drawing’, etc. The article covers this issue in relation to the ever wider use of computers in present times. Due to external determinants it is sometimes perceived as pejorative; however, it does not necessarily have to be true. In this work the author analyses the above-mentioned phenomena in reference to manifold criteria of defining and the description of architectural drawing, as well as on the basis of theories concerning designing. Simultaneously, an attempt is made to include these ponderings and conclusions in an outline of the theory of choice that the author is currently elaborating. The theory assumes the possibility of a positive assessment of mutually contradictory theories, which, paradoxically, might lead to interesting results in the sphere of didactics.
