The nation’s leading computer-aided design (CAD) standard has been updated. The American Institute of Architects (AIA), Construction Specifications Institute (CSI) and National Institute of Building Sciences (NIBS) released the newest edition of the United States National CAD Standard (NCS). Version 6 (V6) is available online at the NCSwebsite.
The NCS helps architects, constructors and operators coordinate efforts by classifying electronic design data consistently and making information retrieval easier, the industry groups say. It improves communication among owners and project teams; cuts or eliminates costs of developing and maintaining company-specific standards; and reduces the expense of transferring building data from design applications to facility management applications.
More than 6,000 architectural, engineering and construction (AEC) firms have voluntarily adopted the NCS in their workplaces. For this edition, NCS owners submitted an unprecedented 379 ballot items.
The new edition includes:
• New implementation guidelines on how to successfully implement the NCS for building information modeling (BIM) use.
• An improved style format.
• An enhanced and improved Symbols Library. New “Survey/Mapping” Discipline Designators.
• New Major and Minor Groups definitions added for “Airports and Plumbing.”
• A revised “Module 1 – File Naming” section to better address Model Files and Sheet Files.
• A Revised “Module 4 – Drafting Conventions, 4.2 Drawing Standards” list of common scales to add “Site/Civil” scale descriptions.
• A Revised “Module 4 – Drafting Conventions, 4.3 Sheet Types” section, which includes a new “Floor Numbering” format.
• New and revised “Communications” terms and abbreviations.
• A Revised “Module 7 – Notations, 7.4 User’s Guide” text format for notes.
• A Revised “Plotting Guidelines” introduction.
