Tekla Structures settings are managed on several layers. On the highest layer there are hard-coded default settings that you cannot change directly but that you can override on lower layers.

1. Common environment settings that have preset values included in the installation. The common environment is always included in the installation.

   Do not modify or remove the common settings.

2. Regional environment settings with preset values that are suited for specific regional areas.

3. The advanced option XS_FIRM that defines a folder, typically on a network drive, that loads settings for all users within your company.

   This folder is the main container of files for the company.

4. The advanced option XS_PROJECT that defines a folder, typically on a network drive, that loads important settings for all users within a specific project.

5. The model template that is loaded from the environment, or from the network folders. The model template is loaded only once when you start creating a new model.

6. The model folder content that is saved locally when you add or edit settings.

   If you save content in the model folder, the saved settings in other locations override the same settings in the model folder.

7. The Windows AppData folder for user-specific settings related to the Tekla Structures user interface.
