ERDC/ITL TR-12-1; Release 2.0AbstractThe A/E/C Graphics Standard has been developed by the CAD/BIMTechnology Center to document how proper hand-drafting practices canbe achieved in Building Information Modeling (BIM), Civil InformationModeling (CIM), and Computer-Aided Design (CAD). It is through thecollection and documentation of these practices that consistent modelsand drawings shall be achieved throughout the U.S. Army Corps ofEngineers (USACE), as well as other federal agencies. In the collection ofthese practices, various historical USACE District drafting manuals wereconsulted and compared against practices contained in various industryand national standards. The documentation of these practices will help toachieve both clear and aesthetically pleasing construction documents.DISCLAIMER: The contents of this report are not to be used for advertising, publication, or promotional purposes.Citation of trade names does not constitute an official endorsement or approval of the use of such commercial products.All product names and trademarks cited are the property of their respective owners.
