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 enable a
building contractor to construct it, as a record of the completed work, and to make a record of a building that already exists.
