Setting config.pro Options
Each configuration file option in config.pro contains a default value that is set by Creo Parametric. If you do not change an option, Creo Parametric uses the default value.
There are two methods to change a config.pro option:
Click Tools > Options and use the Options dialog box.
Open the config.pro file from within a text editor such as Notepad or Microsoft Word, and add or change configuration options directly.
In general, you should change config.pro file settings before you start a Creo Parametric session. If you want to change the environment during a session, it is usually more convenient to use the Environment dialog box, accessed by clicking Tools > Environment. However, you can change some config.pro options only by editing the file directly, by using one of the two methods mentioned previously.
You can save multiple versions of the config.pro file, with each file containing unique settings. This approach is useful if you want to use different configuration settings for different models, and you do not want to change multiple options for the same config.pro file as needed. You save different versions by using the Options dialog box.
