Setting a configuration parameter through a parameter file (TDK)
You can set Configuration Parameters through Configuration Parameter files.
By default, TDK (and ACS) looks in the ItsShadow\Exe folder a Configuration Parameter File named ShdConfig.par and then TDK looks in the same folder for a Configuration Parameter File named TdkConfig.par. When a Configuration Parameter File is found, that file's Configuration Parameters are processed.
In a Configuration Parameter file you can use the ParamFile configuration parameter to reference a different Configuration Parameter file.
To create a configuration parameter file for TDK:
1. Using a text editor, such as Notepad, create a text file named TdkConfig.par.
2. Save the file in the ItsShadow\Exe folder.
If you have installed Modeler to the default location, the path of the ItsShadow\Exe folder is as follows.
For 64-bit versions of Windows:
C:\Program Files (x86)\PTC Integrity Modeler\Modeler\ItsShadow\Exe
For 32-bit versions of Windows:
C:\Program Files\PTC Integrity Modeler\Modeler\ItsShadow\Exe
To set configuration parameters through a configuration parameter file for TDK:
1. Using a text editor, such as Notepad, open the TdkConfig.par configuration parameter file.
2. Type the names of the Configuration Parameters and any values you want to set. Ensure that each Configuration Parameter starts on a new line and is not prefixed with a dash.
For more information about the available Configuration Parameters, see Overview of configuration parameters (TDK).
