Architectural comprehension as a box offers with illustration as a synthesis of numerous efforts – optimistic, compositional, spatial, and technical qualities – which might be then articulated in the built development. For this function, it is very important to take into consideration the graphic illustration that presupposes a lot of these efforts, since it’s each a process and a product of architectural design.
In this feeling, it may be understood that architectural debate during historical past, at other classes of time, was once translated into drawings. The drawing workout refers immediately to the discourse at the back of the paintings of architects of all colleges, actions, and classes. Therefore, in addition to the aesthetic, formal and optimistic alternatives, illustration choices also are a subject of debate amongst pros and theoreticians in the box. In a textual content on fresh design methods in São Paulo, Mario Biselli and Ana Gabriela Godinho Lima say that “as an highbrow and cultural product, structure has a lot to mention and give a contribution; it’s an task that requires and mobilizes a type of artificial, syncretic and dynamic intelligence.” 
Floor plans, sections, and elevations are a conventional representational triad that architects use in their initiatives. However, it’s imaginable to deduce that the segment is, and traditionally has been, the maximum fascinating drawing since it’s understood as a illustration of the architectural design itself.
It is in the segment that the conceptual design turns into nearly actual. It illustrates the vertical size of the drawing, this is, the size that pertains to the person scale with proportional notions. In Manual of Section, Paul Lewis, Marc Tsutumaki and David J. Lewis state that “the segment is the position the place house, shape, and subject matter meet with human revel in.”  In addition, it is usually the consultant device that puts the venture in discussion with its context, and with the topography of the house that it occupies. It is even matter to the barriers of illustration, like every drawing, it may concurrently synthesize the formal, programmatic, optimistic, compositional, spatial, and organizational problems of the venture.
The segment may be crucial in the debate that permits fresh structure on a trail of overcoming trendy precepts which, according to the five issues of Le Corbusier, regarded as the “unfastened plan” as the defining organizational essential of structure. Rem Koolhaas launches from that, in his venture for the 1989 National Library of France festival, with the concept of the “unfastened segment.”
An excessively notable and present instance of this process is the Moreira Salles Institute in São Paulo. The steel construction that helps a translucent double-layer glass pores and skin is arranged vertically. For example, with the escalators being a essential section of the venture.
Although commonplace in fresh works, the vertical or sectional solution to design has been used traditionally. Archigram‘s 1960s conceptual proposals use this graphical device to create diagrams and drawings that specific infrastructural inventions for world initiatives that oppose the proposals from Europe.
This additionally came about in Latin America, with Argentinean architect Clorindo Testa‘s National Library in Buenos Aires and the Bank of London. Both initiatives provide sections of nice expressiveness that divulge the rationale concerned in his works.
In Brazil, Angelo Bucci is possibly an architect whose paintings is maximum mirrored in sections. The Carapicuíba House, designed in partnership with Alvaro Puntoni, finds vertical family members that emphasize the significance of the segment for the design. In discussion with a terrain of nice inclination, the area and place of business are arranged in a distribution that is going with the verticality of the lot, a facet bolstered by means of the illustration in the drawings.
Another instance is Bucci’s House in Ubatuba, which makes use of a topographic determinant to make use of verticality as the place to begin of the venture. Located on a hillside, the home is supported by means of 3 massive pillars that serve as as the organizational axes of the environments, organized in volumes hooked up by means of components of vertical movement.
