FOREWORD
In order to establish drafting standards for the preparation of design and construction
documents using Computer Aided Drafting, VA has adopted the entire National CAD
Standard, latest release, and amended by this guide.
For topics not addressed in this Guide, the procedures and standards in VA Program
Guides PG-18-3, Design and Construction Procedures; and PG-18-15, A/E Submission
Instructions shall be utilized to the maximum extent practicable, commensurate with
cost considerations.
Use of this Guide and the National CAD Standard is mandatory for Office of Facilities
Management Major, Minor and Design-Build projects. Its use is encouraged for minor
and miscellaneous projects at all levels.
The VHA National CAD Standard Application Guide does not apply to National
Cemetery Administration projects. Refer to National Cemetery System Computer-Aided

INTRODUCTION
The Department of Veterans Affairs, in order to standardize and update and its
requirements for CAD documents, is adopting the United States National CAD
Standard, Version 3.1. The National CAD Standard is a publication of the Facility
Information Council of the National Institute of Building Sciences, and may be obtained
from NIBS at the following website: www.nationalcadstandard.org. The standard is a
system for organizing and classifying “drawing centric” building design data, including:
a system for naming model files, drawing files, and drawing file layers; a system for
organizing the drawing set according to drawing set hierarchy, drawing sheet layout and
format, and schedule layout and format; and plotting guidelines.
The VHA National CAD Standard Application Guide establishes the National CAD
Standard as the required basis for CAD documents, and defines amendments that
consist of selected VA-specific CAD requirements which will be retained on a goingforward basis. It also identifies VA documents in the Technical Information Library (TIL)
that it supersedes, and identifies a number of additional VA documents and procedures
that have been modified to bring them into alignment with the National CAD Standard
and the VHA National CAD Standard Application Guide.
Information about the implementation and application of the National CAD Standard and
this Application Guide may be found at http://www.va.gov/facmgt/standard/.
The standard VA title block, a template drawing sheet, and a standard AutoCAD.ctb file
may be found in the TIL at http://www.va.gov/facmgt/standard/details.asp.
2.
CAD SOFTWARE
The recommended CAD software platform is AutoCAD 2000 or AutoCAD LT 2000 by
Autodesk, Inc. More recent AutoCAD releases are acceptable, with downwards
compatibility to the 2000 release.
Other CAD software platforms are acceptable if their output files are convertible to .dwg
format with an acceptable level of accuracy. Other CAD software platforms may also be
acceptable or required in order to match that currently in use at a particular Medical
Center. The Medical Center will choose the particular CAD platform required; the
Medical Centers are urged to strive to employ a uniform CAD platform.

Sheet Numbers
Project Sheet Numbers, as defined in CSI Module 1, are to be prefixed with the building
number. When a drawing reflects work that is associated with several buildings or the
station in general, such as detail sheets and exterior utility distribution systems, no
building number will precede the discipline designators as defined in CSI Module 1 or in
the above table. When sheets are printed they should be organized according to CSI
Module 1. If a project contains multiple buildings the drawings will be organized by
discipline designator not by building number (i.e. a project contains building 100 and
120, when the drawings are organized all the civil sheets for both buildings are put
together, then the architectural sheets for both buildings, etc).
File Naming
The Department of Veterans Affairs, in order to standardize, update, and organize its
CAD documents, requires strict compliance with the file naming conventions specified
herein.
The VA requires that project filenames, as defined in CSI Module 1, are to be prefixed
with the station number, project number, and the building number, separated by
periods. When a drawing reflects work that is associated with several buildings or the
station in general, such as detail sheets and exterior utility distribution systems, no
building number will precede the discipline designators as defined in CSI Module 1 or in
the above table.

Amendments to CSI Module 2, Sheet Organization
Title Block
The VA requires the use of a Standard Title Block, an Architectural F size (30”x 42”). A
drawing file containing the Title Block (referenced), information block, dimension styles,
and text styles, along with the Title Block Drawing, can be obtained from the VA TIL.
The title block reference can be renamed to accommodate multiple aspects of a project
(such as building number).
For Schematic and Design Development-level drawings, and Completion Item drawings,
turn on the appropriate title block layer.
For buildings which are to be fully sprinklered, turn on the title block layer containing the
text "FULLY SPRINKLERED" on each architectural, structural, HVAC, plumbing, and
electrical floor plan.
4.6
Amendments to CSI Module 3, Schedules
No amendments.
Note that the VA Room Finish Schedule is included in the project manual as part of
Master Specification Section 09050, Interior/Exterior Finishes, Materials, and Finish

the use of metric units as the primary drawing units, refer to the following documents,
which are available in the TIL at http://www.va.gov/facmgt/standard/metr_idx.asp:
Metric Implementation (VHA Directive)
GSA Metric Guide (10-93)
Metric Guide for Federal Construction (4-93)

Symbols specific to VA, which are not depicted in Module 6, are included in the VA
Standard Details. CAD blocks of these symbols are also available in the TIL in their
respective discipline Standard Detail sections.
Note: If using drawing provided in the UDS (Uniform Drawing System) software
provided with Volume 2 of the National CAD Standard Version 3, remove any block
construction text and convert from Metric to English units (scale down by 25.4).
4.10
Amendments to CSI Module 7, Notations
This Module has not been formally adopted by VA, however its use is recommended in
order to maintain uniformity across a drawing set.

Amendments to CSI Module 8, Code Conventions
This Module has not been formally adopted by VA, however its use is recommended in
order to maintain uniformity across a drawing set.
5.
STANDARD DETAILS
Selected VA Standard Details in the TIL were technically updated and redrawn to be
compliant with the National CAD Standard. Other Standard Details were retained in the
TIL for legacy purposes, and may be used for information, but were not redrawn to be
National CAD Standard -Compliant. Refer to the Standard Details portion of the TIL for
more information, at the following link: http://www.va.gov/facmgt/standard/details.asp.
Note: Standard Details are to be stripped of the detail title block before insertion into a
construction drawing and may only be modified by the responsible consultant as
appropriate for a specific project.

APPENDIX A
The tables below contain information assigning colors and linetypes to the most
commonly used layers. Layers names are based on the AIA CAD Layer Guidelines in
Volume 1 of the National CAD Standard. For example new electrical equipment tags the
layer name would be E-POWR-IDEN-N, be Color 4, and have a continuous linetype.
The colors listed below are AutoCAD specific, for other CAD software platforms refer to
the National CAD Standard, Tri-Services Plotting Guidelines.
Note that halftone (50% screen with the exception of 251 which is 15% screened and
used for Civil pavement hatches) is generally used for other disciplines’ use of
architectural drawings as backgrounds, or for layers for Architectural (Color 8) that show
existing physical conditions.
