Architecture as a journey
Introduction
A plan (from the Latin planta)[3] or plane is the representation of a body (building, piece of furniture, piece or any other object) on a horizontal plane "Plane (geometry)". It is obtained through a parallel projection, perpendicular to the horizontal projecting plane. It is one of the main representations of the dihedral system, along with the elevation. The representation of the horizontal section "Section (geometry)") is also called a plan.
In architecture, the plan is a technical drawing that represents, in orthogonal projection and on a "Scale (cartography)" scale, a horizontal section of a building; that is, the figure formed by the walls and partitions at a certain height (normally coinciding with the openings - doors and windows -, so that they can be appreciated), or using graphic resources to allow the representation of these and other architectural elements (such as thinner or discontinuous lines, which allow the representation of elements on the cut, such as arches "Arch (architecture)") and traceries).
The plans of a building")[4] consist largely of floor plans, generally one for each height or level of the building, including the roof plan "Roof (construction)"), which unlike the others, does not section the building, but rather shows it seen from above, just as it would be seen when flying over it, but without perspective distortions (bird's eye view).
Accompanying the horizontal plans or sections, vertical section plans (called "Section (geometry)" sections or "section plans") are also used, as well as elevation plans, which show the external appearance of the different facades of the building, without sectioning it.
There are different types of floor plans depending on what you want to represent. The main ones are:
The delineation of the floor plan of a building is called iconography (from the Greek ἰχνογραφία, 'representation of the floor plan'). This was established by Vitruvius in his work De architectura, along with ortographia for elevation and scenographia for perspective. During the Middle Ages the term fell into disuse, but it was recovered in the Renaissance by authors such as Juan de Herrera.[5].

The generalized model was that of a rectangle of proportions approximate to the golden ratio[6] around an axis of symmetry (astronomically oriented from east to west in certain cases)[7] that marked the access through an avenue of sphinxes "Sphinx (mythology)") through a door flanked by thick pylons. The different porticoed courtyards and rooms (hypostyle room, hypetra room) with roofs supported by thick columns "Column (architecture)") become increasingly smaller until the most sacred sanctuary, which is usually designated with the Latin expression .
