In the context of the modern building trade, refers to drawings or copies of drawings that are kept as file records after completion of a project; may include as-built drawings, which indicate changes made during construction. In historical contexts, refers to copies of architects' design drawings, often on a reduced scale, whether executed or unexecuted designs, kept as records of their work. For scale drawings made from existing structures, generally, use "measured drawings"; for drawings that generally depict actual locations, use "topographical views."
