The design and dimensioning criteria of the Gothic structures are currently not well known. This is exacerbated in the Spanish case, by the lack of coeval treaties like the Central European ones. These compile many simple numerical and geometrical rules, which could be analogous to the Spanish ones. These will be studied based on the cathedral traces of Seville and Segovia, drawn to scale and with labelled dimensions, specifying the length and width of the different building parts, and the pillars and walls sections. These elements and the buttresses compose the vertical structure. They are the main purpose of this study, for which the Late Gothic treaties are considered as a reference. Different hypotheses about the Spanish structural rules have been formulated, which could have been used by the masters for an initial dimensioning, drawn in the trace. This was enough to start the building ensuring technical feasibility.
