Drawings or Plans are a set of two-dimensional diagrams or drawings used to describe a place or object, or to communicate building or fabrication instructions.

What it meansEdit

The term Drawings may casually be used to refer to a single view, sheet, or drawing in a set of plans. More accurately, plan refers to an orthographic projection looking down on the object, such as in a plan view, floor plan or bird's-eye view.

How doneEdit

Usually plans are drawn or printed on paper, but they can take the form of a digital file.

Plans are often referred to as "blueprints" or "bluelines". However, the terms are rapidly becoming an anachronism, since most copies of plans that were formerly made using a chemical-printing process that yielded graphics on blue-colored paper or, alternatively, of blue-lines on white paper, have been superseded by more modern reproduction processes that yield black or multi colour lines on white paper.

ReprsentationEdit

FirstlyEdit

Plans are often for technical purposes such as architecture, engineering, or planning. Their purpose in these disciplines is to accurately and unambiguously capture all the geometric features of a site, building, product or component.

SecomdlyEdit

Plans can also be for presentation or orientation purposes, and as such are often less detailed versions of the former.

ThirdlyEdit

The end goal of plans is either to portray an existing place or object, or to convey enough information to allow a builder or manufacturer to realize a design.

NamingEdit

The process of producing plans, and the skill involved, is often referred to as technical drawing.

FormatEdit

Plans are often prepared in a set. The set includes all the information required for the purpose of the set, and may exclude views or projections which are unnecessary. A set of plans can be on standard office-sized paper or on large sheets.

ScaleEdit

Plans are usually scale drawings, meaning that the plans are drawn at specific ratio relative to the actual size of the place or object.

Views and projectionsEdit

Because plans represent three-dimensional objects on a two-dimensional plane, the use of views or projections is crucial to the legibility of plans. Each projection is achieved by assuming a vantage point from which to see the place or object, and a type of projection.
