ERDC/ITL TR-12-6 'A/E/C CAD Standard: Release 6.0'

1 ERDC/ITL TR-12-6 . The CAD/BIM Technology Center for facilities, infrastructure, and environment A/E/ c cad standard Release August 2015. The A/E/ c cad standard is a Department of Defense (DoD). implementation of various industry Information Technology Laboratory and national standards , including but not limited to, the National CAD. Standard (NCS); the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE); and the National Fire Protection Association (NFPA). The A/E/ c cad standard and associated resource files contain supplemental materials and DoD. specific requirements/interpretations not addressed in industry/national standards .

2 Approved for public Release ; distribution is unlimited. The Army Engineer Research and Development Center (ERDC) solves the nation's toughest engineering and environmental challenges. ERDC develops innovative solutions in civil and military engineering, geospatial sciences, water resources, and environmental sciences for the Army, the Department of Defense, civilian agencies, and our nation's public good.

3 Prepared for Army Engineer Research and Development Center Vicksburg, MS 39180-6199. ERDC/ITL TR-12-6 ; Release ii Abstract The A/E/ c cad standard has been developed by the CAD/BIM Technology Center for Facilities, Infrastructure, and Environment to eliminate redundant Computer-Aided Design (CAD) standardization efforts within the Department of Defense (DoD) and the Federal Government. The manual is part of an initiative to develop a nonproprietary CAD standard that incorporates existing industry, national, and international standards and to develop data standards that address the entire life cycle of facilities within the DoD. The material addressed in the A/E/ c cad standard include level/layer assignments, electronic file naming, and standard symbology.

4 The Center's primary goal is to develop a CAD standard that is generic enough to operate under various CAD software packages (such as Bentley's MicroStation and Autodesk's AutoCAD) and incorporate existing industry standards when possible.
