Final answer:
The most common views used in 3-view, orthographic settings are the front view, top view, and one side view. These are part of the first-angle orthographic projection, which allows for dimensionally accurate 2D representation of objects, differentiating it from perspective drawing that uses vanishing points for depicting 3D space.
Explanation:
The most common views used in 3-view, orthographic settings are the front view, top view, and one side view. This configuration constitutes what is known as first-angle orthographic projection. In first-angle orthographic projection, the object is imagined to be placed in a box, with the front view on the upper left block, which is followed by the construction lines that help draw the top and side (end) views.
This method is crucial for accurately representing objects in a 2D format while preserving their spatial relationships, dimensions, and overall geometry. Orthographic projection is distinct from perspective drawing, which involves vanishing points to represent three-dimensional space on a two-dimensional surface, such as paper or a screen.
In the context of perspective, there can be one-, two-, or three-point perspectives depending on the number of vanishing points used to convey depth. Orthographic projection foregoes such vanishing points, thus preserving the scale and proportions of the object without distortion.
