Often states, provinces, cities, architectural and engineering firms receive an abundance of data, from various sources, in the form of drawings. There is a need to standardize the incoming data as it is added to a library of drawings, or included in a GIS map. The intent is to design a system of naming conventions, symbols and drawing object relationships that is both comprehensive and easy to follow. Standards may include, for example, layer names (with full descriptions and properties), block definitions, dimension styles, line types, line weights, layouts, system variables, plotting and scales. The scope of the standards is determined by the client, and may include in-house conventions and formulas, as well as those set by industry or government.
