Architectural Drawing is a critical component of the design process in architecture. It involves various methods for creating design drawings using both analog and digital techniques. The process is based on our ability to see and imagine physical forms and objects, and then translate three-dimensional geometry into two-dimensional representations through descriptive geometry and projection techniques.

Various historical and contemporary drawing methods have been developed to help architects and designers visualize, represent, and communicate information effectively. These techniques include hand sketches, technical drawings, three-dimensional projections, simulations, and visualizations. They can be applied at different stages of the architectural design process, expanding the tools available to architects and designers.

The role of architectural drawing has evolved, and the field now ranges from analog representations based on visual observation to computational simulations based on input parameters and data. This expansion has led to a new paradigm in architectural representation and the education of architectural drawing. It ranges from the development of visual acuity and dexterity required for hand sketching and drawing to the development of coding skills for generating computational simulations and visualizations.

Drawing and Perception play an essential role in architectural drawing. A line is the simplest form of drawing, and it can be defined as a dot that goes for a walk. The act of drawing has been used throughout human history to express thoughts and communicate information. From prehistoric markings found on the walls of caves to contemporary data visualizations generated by computational processes, humans have utilized various types of tools to create drawings.

For example, Paul Klee’s drawing titled In Engelshut (In Angel’s Care) appears to be a simple illustration of a few closed shapes. However, the overlapping shapes generate other figures and blur the reading of any one specific figure. The resulting nonhierarchical juxtaposition of shapes creates a visual ambiguity in the drawing, which shifts depending on how the viewer combines the various shapes in their mind. The simultaneous reading of various figural elements and shape combinations creates a visual complexity through the use of a few relatively simple lines and shapes.

In summary, the role of architectural drawing in the construction of buildings is critical. Various drawing methods provide architects and designers with the ability to visualize, represent, and communicate information effectively. The field of architectural drawing is continuously evolving, and new techniques are being developed to expand the tools available to architects and designers.
