214.3 3 PC Criteria Files
ODOT has developed various 3PC applications, which are used in conjunction with the GEOPAK Design
and Computation Manager. These applications can be obtained from the ODOT CADD Standards
website.
Three Port Criteria files run from the GEOPAK Design and Computation Manager shall have a .3pc file
extension.
The configuration variable GPK_DC_3PCDIR is used to specify the directory location containing the 3PC
applications.
Users are permitted to copy and modify the 3PC criteria files as necessary to achieve the desired results.
Modified 3PC 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 store new or modified 3PC criteria files in the project’s
\geopak\criteria\3pc sub-directory. See Section 302 Project Directory Structure for information on project
directories.
214.4 Cross Section Input Files
Cross sections can be processed in GEOPAK through a dialog box interface by use of the GEOPAK
Project Manager, or by an ASCII input file.
All cross section input files used on the project shall be submitted to ODOT. Input files shall be stored in
the project’s \geopak\input sub-directory.
Cross Section input files shall use relative paths where applicable.
