Go. Grid parameters include two sequence variables that specify the grid's horizontal and vertical spacing units. Standard layouts of drawing sheets are specified by the various standards organizations. For example if the subject is a theatre set, or one for a film or a television show, the designer’s ground-plans become essential information used by almost all the other production departments. In the collection of these practices, various historical USACE District drafting manuals were consulted and compared against practices contained in various industry and national standards. 4. LANL Standard Drawings and Details either (1) depict required format/content or (2) are templates that are completed by a Design Agency (LANL or external AE) for a design drawing package, in a manner similar to specifications. Because drawings tend to be large and complex, finding a specific point or piece of equipment on a drawing can be quite difficult.
