Constructional disabilities are often tested by asking the patient to draw a 2D model or assemble an object. Some researchers feel that neuronal mechanisms involved in drawing and copying differ, thus they should be tested individually. Free drawing is a commonly used test in which the patient is asked to draw a named object.
Box-drawing characters, also known as line-drawing characters, are a form of semigraphics widely used in text user interfaces to draw various geometric frames and boxes.

Sketching is the most inexpensive art medium. [5] Sketches can be made in any drawing medium.
The model's level of experience and skill may be taken into account in determining the length of the posing session and the difficulty of the poses. [4]: 9–10 Models usually pose on a raised platform called the model stand or dais. When artists are working standing at easels, a model stand is essential to avoid a distorted perspective.
