In orthographic projection, which views are most commonly presented?

In orthographic projection, the most commonly presented views are the top view, front view, and right side view. This combination provides a comprehensive understanding of the object's dimensions and shapes from the most critical perspectives.

The top view offers a horizontal perspective that displays the layout and spatial relationships between components as seen from above. The front view presents the object's height and width, allowing for an understanding of the design's vertical profile. The right side view complements these by showing the depth and any features that are not visible from the front or above. Together, these three views can effectively illustrate the geometric details of an object, making them the standard in engineering and architectural drawings.

Other combinations, such as those that include rear or left side views, might provide additional perspectives but are not as commonly used as the top, front, and right side views in standard practice. Additionally, including a bottom view or other angles might complicate the basic interpretation of the design without conveying essential information. Hence, the primary focus remains on the top, front, and right side views to deliver a clear and concise representation of the object.
