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.

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
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
- DOT-31 - Filled Font
- Used on the "New Jersey Works" sign detail and in
- 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
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
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.
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
- Master Roadway 2D Seed File
- Master Structures 2D Seed File
- Master Engineering 3D Seed File
- Electrical Seed - See Traffic Signal &
- Electrical/ITS Seed - under development
CADD Standards Manual English
Writen 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.
These include the Roadway Construction Details, Traffic Control, Bridge Construction, ITS and Electrical.
These include Bridge Standard Drawing Plates adn Standard Drawings for Eoverhead & Cantilever Sign Support Sturcutres in both DGN and PDF.
They are for uniformity in plan presentation, and are intended to illustrate presentation format and standards, and are only available as PDF files.
