notification_report.xsr

This file is used to show a notification report of assignments when you open a model.

options_model.db and options_drawings.db

Contain values for model-specific options from the Options dialog and values for model-specific advanced options from the Advanced options dialog.

When a model is created, Tekla Structures reads model-specific options and advanced options values from the standard.opt file and .ini files in the environment folders and saves them in these two databases.

save_history.log

Each time the model is saved, Tekla Structures stores the information in this file. The file includes the time and date that the file was saved, and information about any conflicts during saving.

TeklaStructuresModel.xml

Contains a copy of basic details about the Tekla Structures model, such as the model name, the version it was last saved with, and the Tekla Structures environment that was used. Tekla Structures overwrites the details in this file each time the model is saved.

The model details that you see when you select a model on the startup screen are read from this file. The file can also be used as an information source for external tools, such as scripts.

wizard.txt

Tekla Structures stores information in this file when you run a drawing rule set (wizard) file. The file contains information such as errors, the number of drawings created, and information about which commands were used.

WorkTypeProperties.xml

Lists allowed property types and their units.

Worktypes.xml

Lists available task types. This file is created when you start the Task manager.

xs_user.<username>

Contains interface settings specified by the user.

This file contains settings for many of the options in the Options dialog and the settings for the icons on the Selecting and Snapping toolbars.

Each time a model is saved, an xs_user.<username> file is created or updated. These settings are user-specific.

If the xs_user.<username> file is not found in the model folder when you open the model, Tekla Structures searches for the xs_user.default file in the following folder search order:

1. Model folder

2. model\attributes

3. Project folder

4. XS_FIRM\attributes

5. System folder

If this file is not found, the default settings for Tekla Structures default settings are used.
