SECTION 1 - INTRODUCTION

The Department of Transportation Southeast Region is in the process of upgrading CAD
systems which involves switching from AutoDesk’s Land Desktop program to AutoDesk’s Civil
3D program.

Prior to the switch, each of the Alaska DOT Regions used varying proprietary CAD Standards
which greatly inhibited the ability to share drawings and electronic design information between
DOT regions and between DOT and private consultants. Over the last two decades as
engineering firms became dependent on CAD programs and developed multiple proprietary
CAD standards, core CAD users began to recognize the need for a global CAD standard to
standardize drawing information and improve electronic data sharing between disciplines and
between firms.

Global CAD standards streamline the exchange of design and construction data between
groups by creating a common “language” of data classification and organization. They also
remove the need to maintain multiple plot style files, the need to train staff on multiple
proprietary CAD standards, and the need to maintain multiple layering guide documents to be
able to decipher layer codes.

Because Civil3D has the U.S. National CAD Standards built into the program, SE DOT
administration decided that this upgrade offers the timely opportunity to transition from the SE
DOT proprietary CAD standard to the National CAD Standards (NCS). This step will streamline
information sharing between the SE DOT and other consultants that are already using the NCS,
and it will make information sharing between the SE DOT and Central DOT easier when Central
DOT makes the expected transition to National CAD Standards during their upgrade to
AutoDesk Civil 3D.

The purpose of this standards document is to provide a tight internal SE DOT specification for
producing design and construction drawings. The full version of the NCS can be found on the
server at: Q:\_Lib\Standards\_National CAD Standard\NCS_31.pdf.

The standards outlined in this document substantially conform to the 2006 NCS Version 3.1.
However, the SE DOT follows its own guidelines for naming and organizing CAD files, and it
follows the Highway Plans Standardization Guide for naming sheets.

SECTION 2 - DRAWING LOCATION
ENGINEERING DESIGN DRAWINGS

  1. All engineering drawings (design and reconnaissance) shall be saved in the C3D project
     structure under the EN folder. The structure is shown below.




  2. To decrease individual drawing sizes, use data references to distribute the engineering
     model across multiple drawings.
        a. Create separate drawings for each of the four major Civil 3D design objects:
                  1) Surfaces
                  2) Alignments & Profiles
                  3) Corridors
                  4) Pipe Networks
                  5) View Frame Groups (if desired)
        b. Save the design object drawings in the appropriate folders inside the SOURCE
            DWGS folder. This excludes existing ground surface drawings. Reference EG
            surface drawings from the appropriate survey folder. Corridor, Alignment, and
            Profile drawings shall be saved in the ALIGNMENTS FOLDER and may be
            merged into one drawing on smaller projects if desired.


                                                                                  Page 7 of 35 
                                                                SECTION 2 - DRAWING LOCATION

                                                                                                 
        c. Create data shortcuts for the design objects. See the AutoCAD help files and
            tutorials for additional information about creating and using data references.
  3. Create a master drawing in the SHEET COMPILATION folder with each of the final
     design objects referenced in it. This drawing will serve as the base sheet for the plan
     production drawings. The Corridor code set style shall be set to Plan Production in the
     Sheet Compilation drawing. Because C3D design objects are dynamic, the Sheet
     Compilation drawing will “synchronize” with referenced data links when those objects are
     updated or modified.
  4. Below is a sample Civil 3D drawing data structure.

PLAN PRODUCTION DRAWINGS

  1. All current plan sheets shall be saved in the PLANSET folder.
  2. XREF the Sheet Compilation drawing for the Plan Production drawing base sheet.
  3. Use the DR directory for scratch drawings and pre-planset sketches.
  4. All current XREFS (excluding the Sheet Compilation drawing and any XREF’d survey
     drawings) will be saved in a folder called XREFS under the planset folder.
  5. All Corp Permit Sheets will be saved in a folder called CORP under the planset directory.
  6. All other drawings created by CAD staff shall be saved in the DR folder.

SECTION 3 - DRAWING NAMING CONVENTION
ENGINEERING DESIGN DRAWINGS

  1. There is no standard naming format for engineering design drawings. Use names that
     are meaningful and will be useful to others trying to locate specific information.

PLAN PRODUCTION DRAWINGS

  1. All Planset drawings shall be saved in the PLANSET folder and use the following naming
     convention:
         • (Project #) + (Sheet #’s) + (Brief Description)
         • Example: 68366_B1-6_Typicals.dwg
  2. All XREF Drawings shall be saved in the XREF folder under the PLANSET folder and
     use the following naming convention:
         • (X for Xref) + (Project #) + (Brief Description)
         • Example: X68366_TB-PLAN.dwg
  3. All Corp Permit Drawings shall be saved in the PLANSET folder and use the following
     naming convention:
         • (CP for Corp Permit) + (Project #) + (Sheet #’s) + (Brief Description)
         • Example: CP68366_1-25_Plan.dwg

SECTION 4 - DRAWING SETUP
DRAWING TEMPLATE

  1. The DOT C3D Standard template drawing is located on the server at:
     Q:\_Lib\Standards\Civil3D\Templates\Standards\ _Alaska DOT C3D Standard.dwt
  2. This template has DOT C3D styles, fonts, dimension styles, and most of the NCS
     Annotation, Aviation, Roadway, and Survey layers already loaded in the template. It
     does not have structural layers loaded. The default template paths in Civil 3D options
     should point to the path and template listed above. If the default path does not point to
     the path listed above, contact the CAD Manager for assistance in configuring C3D to SE
     standards.
  3. The plan production template is saved on the server at:
     Q:\_Lib\Standards\Civil3D\Templates\Standards\Plan Production\_C3D DOT TB-
     Production.dwt

CONVERTING LD DRAWINGS INTO C3D DRAWINGS

  1. When starting a new project in C3D, start with the DOT Standard template drawing.
     If it is necessary to pull in existing information from a Land Desktop drawing, use the
     C3D import option to import the Land Desktop data into C3D. DO NOT MERELY OPEN
     AN EXISTING LAND DESKTOP (LD) DRAWING IN C3D AND DO A “SAVE-AS”. The
     import option will bring in existing LD information as C3D design objects. Existing
     linework can then be copied into the C3D drawing using the “copy with base point”
     command. Use the Layer Translator to convert the layer properties from the old CAD
     standard to the new NCS. See Section 5 – Layering, Layer Translator for information
     on the Layer Translators.

SCALE AND UNITS

  1. All CAD drawing models shall be drafted at full scale in engineering units such that one
     drawing unit equals one foot. The only exception to this rule is when working on
     buildings or structures. In this case, CAD drawing models shall be drafted at full scale
     architectural units such that one drawing unit equals one inch.

FONT & TEXT STYLES

  1. Only two fonts are approved for use: Arial and Arial Bold. These shall be the only fonts
     used on Plan & Detail Sheets. There will be two text styles used in all drawings: TT and
     NT. Do not use oblique text.

TEXT SCALES

  1. All text shall be UPPERCASE throughout the plan set.
  2. Dimensions, labels, notes, and drawing titles shall be set to the sizes shown below.

LINETYPES AND LINEWEIGHTS

  1. All line types and line weights shall be set to “by layer”.

PURGE

  1. Prior to submitting final design drawings, the purge command shall be used to eliminate
     all unreferenced blocks, layers, and linetypes.

POLICY ON MODEL SPACE AND PAPER SPACE

  1. All drawing models shall be drawn in model space and shall be drawn to scale. Any
     additional item that helps define the model or add model data such as details,
     dimensions, elevations, names, descriptive text, or sections should be drawn to full scale
     in model space.
  2. All secondary drawing elements shall be created in Paper Space. Title block, sheet
     notes, schedules, titles, and legends shall be considered secondary drawing elements.
  3. Note: Survey information referenced in design drawings shall not be moved or
     rotated from the original coordinates used in the survey drawing. When copying
     model space information between drawings, verify that the UCS coordinates in
     both drawings are set to “World” prior to executing the copy-paste commands.

POLICY ON EXTERNAL REFERENCE FILES (XREF’s)

  1. All externally referenced source drawings (XREF’s) shall be inserted on layer C-ANNO-
     REFR, and this layer shall remain locked to avoid accidentally moving the reference
     drawing from its original coordinates.
  2. At the end of a project after the final Plan Sheets have been signed, all externally
     referenced source drawings (XREF’s) that were used during the CAD drawing
     production phase shall be inserted (using the bind command) and retained as blocks
     within the Planset drawings. This will prevent errors and missing links from developing
     when the Planset drawings are later archived or relocated on the server.

LAYER NAME FORMATTING

As recommended by the NCS Layer Guidelines, layer names may be as short as six characters
(discipline code + major group). Here are four examples of acceptable formula variations, with
explanations of formula variables found below:

       #1     C -ROAD = discipline code + major group
       #2     C –ROAD-CURB = discipline code + major group + minor group
       #3     C –ROAD-CURB-TEXT= discipline code + major group + minor group + minor
       #4     C –ROAD-CURB-E = discipline code + major group + minor group + status

   Discipline Code:
   The discipline code is a two-character field with the second character being either a hyphen
   or a NCS-defined modifier. The predefined discipline codes are the same for both layer
   names and file names. For a complete list of discipline codes, see the NCS Layer
   Guidelines.

   Major Group:
   The major group designation is a four-character field that identifies the system, such as
   roads, right-of-way, buildings, etc. Although most major groups are logically associated with
   specific discipline codes, it is possible to combine major group codes with any of the
   discipline codes. For example, C-ROAD or V-ROAD.

   Minor Group:
   This is an optional, four-character field for further differentiation of major groups. For
   example, paved roads (C-ROAD-ASPH) might be differentiated from unpaved roads (C-
   ROAD-UPVD).

   If necessary, the minor group field may also be defined by the user, allowing additional
   layers to be added to accommodate special project requirements. However, this should only
   be done after checking NCS Layer Guidelines to see if any of the predefined layer names in
   that list would meet the special project requirements.

   Status Field:
   The status field is an optional single-character designator that distinguishes the data
   contained on the layer according to the status of the work or construction phase. It is only
   needed when phases of work must be differentiated such as C-ROAD-N or C-ROAD-E. In
   either case, the status field is always the last single-digit character of the layer name. In the
   DOT layer standards, all survey layers are assumed to show existing work to remain
   and all civil layers are assumed to show new work. Where these assumptions are true,
   status fields are not necessary.

   Defined values for the status field as defined by the NCS are as follows:

   N        New Work
   E        Existing to Remain
   D        Existing to Demolish


                                                                                       Page 24 of 35 
                                                                        SECTION 4 - DRAWING SETUP

                                                                                                        
   F         Future Work
   T         Temporary Work
   M         Items to be Moved
   X         Not In Contract
   1-9       Phase Numbers (1-9)

   Layer uses are generally implied by the layer name. However, the following explanation of
   certain layer use rules should be noted.

         Status Field / Dominant Phase Rule:
         Layers representing the dominant phase of a project can be represented without a status
         field. For example, in a small remodeling project, -N would indicate new construction,
         while layers without status fields would indicate parts of the existing building to remain.
         Conversely, a remodeling project consisting of mostly new construction might use -E to
         indicate “existing to remain” building systems while all layers without a status field
         designator would represent new construction.

         Annotation and Title Blocks:
         Annotation refers to text, dimensions, title block and sheet borders, detail references and
         other elements on CAD drawings that do not represent physical aspects of the model
         drawing. Annotation is designated by the major group ANNO, which can be combined
         with any discipline code. Types of annotation are designated below (asterisk represents
         any discipline code):
         *-ANNO-DIMS dimensions
         *-ANNO-KEYN keynotes
         *-ANNO-LEGN legends and schedules
         *-ANNO-NOTE notes
         *-ANNO-NPLT construction lines, non-plotting information, viewports
         *-ANNO-REDL redlines
         *-ANNO-REVS revisions
         *-ANNO-SYMB symbols
         *-ANNO-TEXT text
         *-ANNO-TTLB title blocks and sheet borders
         Annotation can be placed in both model space and paper space (see Policy on Model
         Space and Paper Space). The same layer names would be used in either case.

LAYER TRANSLATION – TRANSLATING DOT LAYERS TO NCS LAYERS

This section contains a list of the old DOT CAD standard layers and gives the new NCS layer
names and layer properties. The NCS layers listed are only a partial list of the layers available
through the NCS. See the CAD Layer Guidelines published in version 3.1 of the U.S. National
Cad Standards, pages CLG-1 to CLG-41 for additional layer naming information. These are
located on the Q drive at Q:\_Lib\Standards\_National CAD Standard\NCS_31.pdf .

In the old DOT CAD standard, the second letter of the layer name differentiated between lines,
symbols, text, and hatch. In the NCS layer naming convention, layers describing symbols or


                                                                                       Page 25 of 35 
                                                                       SECTION 4 - DRAWING SETUP

                                                                                                      
text have the minor groups “-symb” or “-text” at the end of the layer name. Layers describing
lines do not require a suffix. For example:

     ELHM         becomes            V-ROAD-MRKG

     ESHM         becomes            V-ROAD-MRKG-SYMB

     ETHM         becomes            V-ROAD-MRKG-TEXT

Layer Translation

There are three AutoCAD standards files on the server that can automatically translate layer
names and properties from the existing DOT standard to the NCS. These translators are
located at Q:\_Lib\Standards\Civil3D\Layer_Translators and are in dws format.

   1. To run the layer translator, type “laytrans” in the command line in C3D. When the dialog
      box opens, click “Load…” and navigate to the standards drawing listed above. This will
      populate the Layer Translation Mappings window and will the list the old layer names
      and the new layer names and properties that will be assigned to the old layers. Click the
      button “Translate” to start the process. When the “Layer Translator Alert” dialog box
      pops up asking to save mapping information changes, click the “No” button.
   2. Only the standard layer names from the DOT CAD standards are mapped. Any non-
      standard layer names will need to be mapped manually.

Layer Translators

   1. DOT to NCS (extg).dws
        a. Translates existing layers to survey layers and are assigned to the survey
            discipline code “V-“.
        b. Note: existing layers are assumed to be survey layers.
   2. DOT to NCS (proposed) .dws
        a. Translates proposed layers to civil design layers and are assigned to the civil
            discipline code “C-“.
        b. Note: proposed layers are assumed to be civil design layers.
   3. DOT to NCS (prop to extg) .dws
        a. Translates proposed layers to civil design layers and shows linework as existing
            design linework but separate form survey information. Layers are assigned to
            the civil discipline code “C-“ and suffixed with “-E” to indicate that the linework is
            existing.
        b. Note: proposed layers are assumed to be civil design linework that has been
            constructed but not surveyed.

STANDARDS CHECK

  1. The C3D ’10 standards file is located at
     Q:\_Lib\Standards\Civil3D\C3D '10\DWTs_Alaska DOT C3D Standard.dws
     It can be used to check drawings for non-standard layer properties and CAD objects and
     to resolve any discrepancies.
  2. To run the _Alaska DOT C3D Standard.dws standards file, type “standards” in the C3D
     command line. When the “Configure Standards” dialog box opens, click the plus button
     and navigate to the standards drawing listed above. After the file loads, click “Check
     Standards…” to check the drawing.
  3. Run the Standards checker prior to plotting final Planset Drawings.
