Architects and others use architectural drawings for a variety of purposes, including developing a design idea into a coherent proposal, communicating ideas and concepts, persuading clients of the merits of a design, allowing a building contractor to construct it, keeping a record of completed work, and making a record of completed work. Architectural plans can also be used as a teaching tool at either an undergraduate or post-graduate level. The main purpose of architectural planning is to produce drawings (often only approximate ones) that accurately represent a person's vision of how they want their project to look. These drawings are then used by architects and other designers when constructing actual buildings or other physical objects. An architectural plan documents the various aspects of a building or other physical structure, including its exterior and interior designs. This document is useful in determining the overall appearance of the building, locating problems within the building, and identifying ways to improve the construction process. The main purpose of architectural drawing is to communicate an artist's or architect's vision of a project. It is often the only means by which these visions can be translated into reality. Architectural drawings play an important role in the development of a building or other physical structure by providing a record of the decisions made during the design process. They can also act as a guide for future modifications to the project.
