options_model.db and Contain values for model-specific

options_drawings.db options from the
Options dialog box
and values for
model-specific
advanced options from the
Advanced
Options dialog box.
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.

history.db Model history

database.

xsdb.xs File used for displaying the name of

the model in the
Open dialog box.

xs_user.<username> Contains interface settings specified

by the user.
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: model,
model\attributes, project, XS_​
FIRM\attributes, system. If
this file is
not found, Tekla Structures default
settings will be used.
This file contains
settings for many of
the options in the
Options dialog
box and the settings
for the icons on
the Selecting and
Snapping
toolbars.

save_history.log Tekla Structures stores the

information in this file
each time the
model is saved. The file includes the
saving time,
date and information on
any conflicts during saving.
