Final answer:
An architect is the professional who designs and oversees the construction of buildings, ensuring the architectural designs are both functional and aesthetically aligned with their intended purpose.
Step-by-step explanation:
The individual who plans and draws the design of buildings and superintends their erection is known as an architect. Architects are responsible for the creation of architectural drawings that adhere to the principle where form follows function, shaping buildings based on their intended purposes. Using lines and a grid system for planning, architects effectively create the spatial organization of buildings, taking into account geometric relationships as well as the functionality of the spaces within.
To illustrate the design and how it will fit into its environment, architects oftentimes build physical models. This was also true historically, as master masons, who understood geometry and arithmetic, directed construction before the modern mathematical engineering theories were developed. Though previously guided by rules of thumb, today's architects incorporate advanced technology, creating detailed designs and overseeing the construction process to ensure the project is realized according to the vision and plans.
