+
+In the Post-Pro module you can set preferences, default settings,
+which can be used in later sessions with this module.
+
+<h2>General Preferences</h2>
+
+\image html ppref0.png
+
+<ul>
+<li><b>Input fields precision</b></li>
+<ul>
+<li><b>Visual data precision</b> - allows to adjust precision of scalar data displayed as text, data values round-up, various visualization options.</li>
+<li><b>Length precision</b> - allows to adjust input precision of coordinates and dimensions.</li>
+<li><b>Angular precision</b> - allows to adjust input precision of angles.</li>
+<li><b>Length tolerance precision</b> - allows to adjust input precision of tolerance of coordinates and dimensions.</li>
+<li><b>Parametric precision</b> - allows to adjust input precision of parametric values.</li>

+
+<h2>MED import Preferences</h2>
+
+\image html ppref1.png
+
+<ul>
+<li><b>MED files import</b></li>
+<ul>
+<li><b>Use Build Progress</b> - when this option is checked you can choose
+all other import MED options at the moment of loading of each file
+using <b>Build Progress</b> menu, otherwise the loading will be done
+according to the <b>Preferences</b> without addressing to the
+user.</li>
+<li><b>Full MED Loading</b> - when this option is checked, the MED file is
+fully loaded in the study, and no additional access to the MED file is
+needed during the session. Reversibly, when unchecked, the MED file is
+loaded on demand. This is the default behaviour in SALOME and
+recommended for big files to optimize memory usage.</li>
+<li><b>Build at once</b> - when this option is checked, you can't
+perform any operations until the MED file is fully loaded and
+processed.</li>
+<li><b>Build fields</b> - when this option is checked, the fields are
+built automatically at loading.</li>
+<li><b>Build min/max</b> - when this option is checked, minimum and
+maximum values of the time stamps are found at loading.</li>
+<li><b>Build groups</b> - when this option is checked, the groups and
+families are built automatically at loading.</li>
+<li><b>Close dialog at finish</b> - when this option is checked, the
+dialog box is closed after loading of the selected MED file. When
+unchecked, it allows loading other MED files.</li>
+</ul>
+</ul>
+
+<br><h2>Scalar Bar Preferences</h2>
+
+\image html pref31.png
+
+<ul>
