If you want to change any of the default settings related to handling of operations (like changing default tolerance angular dimensions) in ProE,then you should change the default value and save it to the Config.pro file. The following steps need to be followed for modifying the Config.pro file:
- Go to Tools>Options, and the Options dialog box will open.
- Settings from the most recently loaded Config.pro will be displayed there.
- You can modify any of already displayed settings by clicking the Value field.
- To know all the possible options can be changed, click the Find button and the Find option dialog box will open as below:

- Put ‘_’ in the keyword field and click Find Now.
- The list of all possible settings will appear with default value and description.
- Change the desired setting
- The option will be added to the list in the main option window.
- Notice the path of storage at top left corner of the Options window. It should be either to the ProE load point directory or your login directory or ProE working directory.
For example, if you change the value of prompt_on_exit from no to yes then you will see that ProE will prompt you to save the unsaved data before exiting.
