Architecture involves in physically designing the world around us, or the environment, according to our needs. This environment is been geometrically defined as a 3-dimensional space (Euclidian Geometry) which comprises with x,y,z axis that describes the height, breadth and length of the space. Architects need to quantify the space simply by measuring the 3-dimensional space in order to create their design at a particular site. Thus, one should aware about handling measuring tools, how to record the measured data, what are the measuring units, etc, on the first hand.
Since architecture directly address the three dimensional space, it sometimes become hard to communicate spatial elements to another person. For an example, communicating the 3-dimensional shape of a house to another person will be more complicated. In architecture, two basic and most popular methods will be used for this purpose: 3-dimensional models (physical or computer generated) and technical drawings. Among these two methods, technical drawings is accepted to be the most accurate and standard way of communicating a design since it provide lot more information both graphically and textually, where text information are less used in 3-dimensional models as there are natural limitations on using such.
Therefore, it could be coined that both measuring the three dimensional space physically and interpreting the three dimensional space through technical drawings is the key fundamental element every architect should learn on first hand.
This tutorial aims on the reader to provide the fundamentals of these two important elements. However, it should be noted that, these two elements cover a vast area which cannot be practically summarized into few pages. Therefore, reader is advised to study, practically involve and question on each of the element in order to be a well sound user of them.
