Final answer:
The two primary functions for drawing are visualization, which is crucial in planning structures like buildings in architecture, and artistic expression, where drawing is used to convey ideas and emotions. Drawing serves as the foundation of all art, embodying the principle that form follows function in various fields, including architecture.
Step-by-step explanation:
The two primary functions for drawing include serving as a tool for visualization and as a medium for artistic expression. The visualization aspect of drawing is essential for professions such as architecture, where architects like Frank Gehry use preliminary sketches to capture the complex organic forms of the buildings they design. This serves as a means to plan compositions which are later made into more permanent forms like paintings, sculptures, or buildings. Another key function is artistic expression, which utilizes drawing as a basic yet profound way to convey thoughts and experiences. Drawing can evoke emotions and tell stories through a series of marks on a surface, being both an intuitive and a deeply human practice to share ideas.
Drawing is fundamental to various fields and disciplines, and it has traditionally embodied the visual principle that form follows function. Especially in the context of architectural drawings, this rule emphasizes that the shape of a structure should be based upon its intended purpose, whether it is a house, village, or larger city layout. Detailed planning utilizing lines and shapes is crucial for creating three-dimensional concepts of a structure, which can be done with traditional tools such as pen and paper or with modern technology like computer software.
