214 GEOPAK Criteria Files
214.1 General
January 18, 2013
Criteria files are ASCII text files written in the GEOPAK Criteria language. Criteria files are primarily used
to draw proposed cross section graphics in a MicroStation design file.
Three Port Criteria (3PC) commands can be used to extend the processing capabilities of GEOPAK
Criteria to draw MicroStation elements in a plan or profile design files in addition to the cross section
design file. For ODOT purposes, criteria files that are processed from the GEOPAK Design and
Computation Manager to draw plan or profile information are referred to as “3PC files”. Criteria files that
are processed from cross section mode are referred to as “criteria files” even though the cross section
criteria file may contain 3PC commands to draw elements in the Plan or Profile design files.
214.2 Cross Section Criteria Files
ODOT has developed a set of criteria files to assist the user with the drawing and detailing of the
proposed cross sections. These criteria files are available on the ODOT CADD Standards website.
The ODOT cross sections criteria files have been developed according to the standards defined in the
Location and Design Manual, Volume 1 – Roadway Design. These criteria files are provided as a
convenience to the user and are not intended to draw all aspects of every cross section correctly. The
designer must take care to review the results and make any modifications necessary to the cross section
graphics to ensure compliance with ODOT design standards.
Cross Section Criteria files shall have an .x file extension.
Users are permitted to copy and modify the criteria files as necessary to achieve the desired results.
Modified criteria files should be renamed to avoid confusion with the ODOT standard criteria files. All new
or modified criteria files shall be submitted to ODOT with the completed project data.
As a standard practice, users should copy all cross section criteria files used on the project to the
project’s \geopak\criteria sub-directory. See Section 302 Project Directory Structure for information on
project directories.
