General Information

CADD information and resource files for Microstation are available for downloading from this site. As much information as is possible has been made available. Please check the revision dates frequently to ensure you are working with the most current versions.

You are encouraged to contact CADD Development with your CADD questions and suggestions via our list of CADD Contacts.

MicroStation CADD Support Files
Cell Libraries

A "cell" in MicroStation is a group of graphical elements that can be manipulated as a single entity. The use of cells enhances CADD productivity and helps promote CADD standardization. The Department's Cells are stored and maintained in cell libraries, which have been broken down by discipline.

  • RoadWay.cel - Master Roadway Cell Library
  • RoadSigns.cel - Master Roadway Sign Cell Library
  • Bridge.cel - Master Structures Cell Library
  • Land.cel - Master Landscape Cell Library
  • Electrical Cell Library - See Traffic Signal & Safety
  • Electrical/ITS Cell Library
Color Table

Standard colors are specified to ensure consistency and to enable users to easily identify plan elements in shared files. Elements are assigned a color "number" which MicroStation reads to determine the correct color to display for that color setting. The Department uses one common master color table.

Font Resource File

Contrasting text styles (fonts) and sizes are used within a drawing to designate different types of information (i.e. existing versus proposed). The Department's font resource file is made up of a combination of converted TrueType fonts, Bit Stream fonts, symbol fonts and basic MicroStation font cell type fonts.

  • DOT-1 (Proposed) - Converted TrueType font (fractional) - Used on construction type sheets for "proposed" lettering.
  • DOT-7 - Fancy Filled Font - Used on the Quantities EDQ sheet and in displays.
  • DOT-11 - Bit Stream Font (straight) - Used for headings and in displays.
  • DOT-19 - Bit Stream Font (slanted) - Used for headings and in displays.
  • DOT-23 (Existing) - Converted TrueType font (fractional) - Used on all construction type sheets for "existing" lettering.
  • DOT-30 - Filled Font - Used on the "New Jersey Works" sign detail and in displays.
  • DOT-31 - Filled Font - Used on the "New Jersey Works" sign detail and in displays.
  • DOT-41 - Upper case only - Used in Landscaping plans
  • DOT-42 - Filled Font - The "default" font (used by MicroStation if the font number doesn't exist in the font resource file)
  • Fonts - 90, 91, 92, 94 - Symbol fonts for InRoads
  • Fonts - 95, 96, 97 - Customized symbol fonts used in InRoads
  • Font 127 - Default fast font - used if "fast font" is set in the design file.
IPLOT Pen Tables

The Department uses IPLOT, a Bentley Systems Inc. product, to produce final plan sets. Individual plotting routines (pen tables) are used to create the final appearance of a MicroStation plot. Pen tables have the ability to change the "look" of individual elements or groups of elements at plot time to achieve the desired plan presentation without affecting the original design file element.

These are approximately 16 pen tables that were written to support the various aspects of in-house design and they may not give an outside user the desired results unless the entire NJDOT CADD system format, set-up and configuration is followed.

Line Style Resource File

For efficiency reasons the Department has added its own user defined lines styles (UDL) to the basic MicroStation line style resource file. These UDLs are graphical representations of features like guide rail, ROW lines, curb, etc. and can be drawn and manipulated as any normal linear element.

When an element is drawn in MicroStation, the definition of the line style is not contained within the design file, only the line style name / number. When the design file is opened, the display is governed by the line style resource file being used at the time.

Seed Files

MicroStation uses a "seed" file concept to create new design files. These seed files are templates in which the standard file parameters (working units, global origin, view attributes, color table, text settings, coordinate readout, etc.) are set to the Department's standards. The Department maintains 2D seed files by discipline and a master 3D seed file for three dimensional applications.

  • Roadway-Seed-2D.dgn - Master Roadway 2D Seed File
  • Bridge-Seed-2D.dgn - Master Structures 2D Seed File
  • InRoads-Seed-3D.dgn - Master Engineering 3D Seed File
  • Electrical Seed - See Traffic Signal & Safety
  • Electrical/ITS Seed - under development
CADD Standards Manual English

Written to create uniformity for the roadway / structure design and drafting, this manual is neither a textbook nor a substitute for engineering or drafting knowledge, experience, or judgment. These standards are neither static nor all-inclusive and thus will be updated and enhanced as appropriate.

The information in this document is based on using MicroStation ".dgn" format, which is a product of Bentley Systems, Inc. It includes information on our Working Units, Global Origin, Level Structure, File Names, File Content, Line Styles, Line Weights, Fonts, Cells and Color Table as used by the Department.

Standard Details

These include the Roadway Construction Details, Traffic Control, Bridge Construction, ITS and Electrical.

Standard Drawings

These include Bridge Standard Drawing Plates and Standard Drawings for Overhead & Cantilever Sign Support Structures in both DGN and PDF.

Sample Plans

They are for uniformity in plan presentation, and are intended to illustrate presentation format and standards, and are only available as PDF files.
