General Information
NJDOT’s Metric Computer Aided Design and Drafting (CADD) information and resource files for
Microstation are available for downloading from this site. We have tried
to make as much information available as possible and will continue
to add and update items in the future. Please check the revision dates
on all files frequently to ensure you are working with the most current
versions.
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
- brmetric.cel - Master Structures Cell Library
- lametric.cel - Master Landscape Cell Library
- Electrical Cell Library
- See Traffic Signal & Safety
The Department’s cell libraries are available for download
as a bundled package in ZIP format on the CADD
Downloads (Metric Units) page of the CADD Support website.
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’s master color table "roads.clr"
is available for download on the CADD
Downloads (Metric Units) page of the CADD Support website.
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 Bit Stream fonts, symbol fonts and modified MicroStation
font cell type fonts.
The Department’s font resource file "roadfont.rsc"
is available for download on the CADD
Downloads (Metric Units) page of the CADD Support website.
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.
The IPLOT pen tables are not available for download from
this site.There are approximately 25 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. If you have questions
and/or would like the latest copies of our IPLOT pen tables, please
contact the " CADD
Support Unit ".
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 line style
resource file being used at the time governs the display.
The Department’s line style resource file "roadlines.rsc
" is available for download on the CADD
Downloads (Metric Units) page of the CADD Support website.
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 two seed files, one for the creation
of 2D files and one for 3D InRoads applications.
The Department’s "Seed Files" are available for
download as a bundled package in ZIP format on the CADD
Downloads (Metric Units) page of the CADD Support website.
Standard Details Metric
The Department’s Standard Details are broken out into "sections"
by discipline. When a standard detail is revised, there will be a "revision
date" and adjacent to the detail number.
Access for downloading the standard details is from the
CADD Downloads (Metric Units)
page of the CADD Support website. The MicroStation ".dgn"
versions of the standard details can be downloaded individually or an
entire "section" can be downloaded as a complete set in a
ZIPed format. Each "section" can also be downloaded in Adobe
PDF format.
CADD Standards Manual Metric
The purpose of this manual is to document the Department’s
Metric CADD standards in an effort to create uniformity for the roadway/ structure design and drafting performed for the N.J. Department of
Transportation. 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 revised as needed.
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.
The NJDOT CADD Standards Manual is available for download
in Adobe PDF format on the CADD
Downloads (Metric Units) page of the CADD Support website.
