An architectural drawing or architect's drawing is a technical drawing of a building (or building project) that falls within the definition of architecture.Architectural drawings are used by architects and others for a number of purposes: to develop a design idea into a coherent proposal, to communicate ideas and concepts, to convince clients of the merits of a design, to assist a building ...
These three views are known as front view (also elevation view), top view or plan view and end view (also profile view or section view). When the plane or axis of the object depicted is not parallel to the projection plane, and where multiple sides of an object are visible in the same image, it is called an auxiliary view .
A plan view is an orthographic projection of a three-dimensional object from the position of a horizontal plane through the object. In other words, a plan is a section viewed from the top. In such views, the portion of the object above the plane (section) is omitted to reveal what lies beyond.
Plans are usually "scale drawings", meaning that the plans are drawn at a specific ratio relative to the actual size of the place or object. Various scales may be used for different drawings in a set. For example, a floor plan may be drawn at 1:48 (or 1/4"=1'-0") whereas a detailed view may be drawn at 1:24 (or 1/2"=1'-0").
View lines or section lines (lines with arrows marked "A-A", "B-B", etc.) define the direction and location of viewing or sectioning. Sometimes a note tells the reader in which zone(s) of the drawing to find the view or section.
Exploded-view drawing of a gear pump. An exploded-view drawing is a technical drawing of an object that shows the relationship or order of assembly of the various parts. [13] It shows the components of an object slightly separated by distance or suspended in surrounding space in the case of a three-dimensional exploded diagram.

[2] [3] Typically in axonometric drawing, as in other types of pictorials, one axis of space is shown to be vertical. In isometric projection , the most commonly used form of axonometric projection in engineering drawing, [ 4 ] the direction of viewing is such that the three axes of space appear equally foreshortened , and there is a common ...
