The ifx_pin_data.cfg Configuration File
In the ifx_pin_data.cfg you can configure the upper and lower tolerance values that appear in the Dowel Pin Fastener Definition dialog box. See the column headings and values of the ifx_pin_data.cfg file in the table below. When editing this file, be sure to press TAB to separate the values.
Column
Value
#TOL or #TOL#<DAT VALUE>
The unit of the dowel pin, either MM or INCH. This is always the first column.
DN
The dowel pin diameter.
STRING
The string you can select from the Tolerance list in the Dowel Pin Fastener Definition dialog box. If an ISO tolerance field such as H7 is entered, then the fit is automatically assigned to the hole diameter. In this case no values for the columns LOWER and UPPER are required.
NOM
The nominal hole diameter.
LOWER
The lower limit dimension.
UPPER
The upper limit dimension.

Set the Creo Intelligent Fastener option PIN_DIAMETER_FOR_HOLECHART to DN or NOM to determine from what column in the ifx_pin_data.cfg file, you get the corresponding hole chart (*.hol).
