+
+As soon as some dimensions have been created and submitted using
+\ref managing_dimensions_page "Manage Dimensions tool",
+they are shown in Text window tree as a child of corresponding parent shape.
+This tree provides a possibility to manage of dimensions visibility using <b>Show</b>/<b>Hide</b> context menu items or
+by click on 'eye' icons in Text window.
+\note Hidden shapes and its dimensions are shown in Text tree, but disabled. Show/Hide operations are not applicable for these objects in such a case.

<ul>
<li><b>Dimensions (Measurements)</b> - a group of preferences controlling the presentation of dimensions.</li>
<ul>
<li><b>Color</b> - allows to define color for persistent dimension presentations.</li>
<li><b>Line width</b> - allows to define pixel width of dimension lines.</li>
-<li><b>Font height</b> - allows to define height of dimension text.</li>
+<li><b>Font</b> - allows to define font family and height of dimension text.
+By default Y14.5M-2009 font is set. It is a standard for the design language of geometric dimensioning.
+But it is possible to select another font supported by OCCT.
+Dimension's height is in pixels for 2D text and in model units for 3D text.</li>
<li><b>Length of arrows</b> - allows to define length of dimension arrows.</li>
<li><b>Length measurement units</b> - allows to define units of measurement for lengths dimensions.</li>
<li><b>Angle measurement units</b> - allows to define units of measurement for angles dimensions.</li>
<li><b>Show units of measurements</b> - when this option is on, the measurement units are added as prefix to value label of dimension.</li>
<li><b>Default flyout length</b> - allows to define default flyout length used when creating the dimensions. The length can be interactively changed after creation by moving the flyouts.</li>
+<li><b>Use 3D text</b> - this option switches the dimension representation from default 2D to 3D: </li>
+<ul>
+<li>2D text is horizontal and parallel to the screen always.</li>
+<li>3D text takes place in plane of measurement and has constant orientation.</li>

It is also possible to change the geometrical properties of the selected dimension interactively in the viewer. \r

\r
All modifications of the dimensions are temporary. The "Apply" and "Apply and Close" buttons save the changes.\r
\r
+If created dimensions are saved, then they are displayed in \ref dimensions_text_window "Text window" as a children of corresponding shapes.\r
