In engineering drawing, the orthographic projection of an object on a certain projection plane is referred to as a view, while the corresponding direction of projection is called the viewing direction; these include front view, top view, and side view.
A projection is the shadow that this figure casts on another horizontal surface as a result of light shining on that surface; that shadow is the projection
A projection diagram is a concept in mechanism design, focusing on the shape and dimensions of an object as seen from a particular side when projected onto that side.
In engineering drawing, the orthographic projection of an object on a certain projection plane is referred to as a view, while the corresponding direction of projection is called the viewing direction; these include front view, top view, and side view. Three views: front view, side view, and top view, which are the three projection diagrams.

When light shines on an object, it creates a shadow on a wall or floor. In drawing, the line that represents the light is called a projection, and the shadow that is formed is known as a projection diagram.
In engineering drawing, the orthographic projection of an object on a certain projection plane is referred to as a view, while the corresponding direction of projection is called the viewing direction; these include front view, top view, and side view. The front projection, horizontal projection, and side projection are respectively called the front view, top view, and side view ； In construction drawing, they are respectively called front elevation (abbreviated as front view), floor plan, and left elevation (abbreviated as side view). The three projection views of an object are collectively referred to as the three-view drawing or three-face view.
