Final answer:
The three conceptual models for drawing are two-dimensional (2D) drawings, three-dimensional (3D) drawings, and conceptual models that underline the ideas and notions behind the drawing.
Step-by-step explanation:
When referring to the three conceptual models (primitives) for drawing, we can think of these as the foundational elements or building blocks used to represent images on a surface. Drawing as an art form is essentially about using these primitives to create a representation of our thoughts, observations, and imaginings.
One of the most basic and widely recognized models is two-dimensional drawing (2D), which involves creating artwork on a flat surface using width and height. This type is often used for sketches, illustrations, and other forms of art that lie on a flat plane.
Another model is three-dimensional drawing (3D), which represents objects that have depth in addition to width and height. Such drawings usually represent buildings, shapes, or objects and are capable of suggesting volume and perspective.
The third model, not as commonly referred to as a primitive but essential nonetheless, is the conceptual model that underpins the art, which refers to the ideas and notions that form the basis of the drawing. This encompasses the symbolism, emotional content, and messages conveyed through the artwork.
