When PTC Creo Schematics starts, customization settings are automatically applied from the working directory:

The following files are stored in the working directory:

To facilitate administration and sharing of user interface information, an administrator can configure the application to retrieve customization settings from a central location. You define a UI customization file location by setting the environment variable UI_CUST_ADMIN_DIR. The variable must be set to include the path to the location. The path can be defined using the \\<machine_name>\shared_folder notation. The name of the customization file should be creo_schematics_admin_customization.ui. When the customization file includes custom command, the creo_schematics_shortcuts.dat file must be placed in that location.

When both the creo_schematics_admin_customization.ui and the creo_schematics_user_customization.ui files exist, the admin file is read and applied first, then the user file is read and applied from the working directory.
