+\page geometry_preferences_page Geometry preferences
+
+In the \b Geometry module you can set preferences for visualisation of
+geometrical figures which can be used in later sessions with this
+module.
+There is also a special group of preferences controlling input precision for floating-point
+data.

+<li><b>General</b></li>
+<ul>
+<li><b>Default display mode</b> - allows to choose between wireframe, shading or 
+shading with edges.</li>
+<li><b>Default shading color</b> - allows to select default shading
+color.</li>
+<li><b>Edges in shading</b> - allows to select default edges color in shading mode.</li>
+<li><b> Default wireframe color</b> - allows to select default
+wireframe color (to be applied to any lines not being free boundaries
+or isolated lines).</li>
+<li><b>Color of free boundaries</b> - allows to select default color for free boundaries.</li>
+<li><b>Color of edges, vectors and wires</b> - allows to select
+default color for edges, vectors and wires (isolated lines).</li>
+<li><b>Color of points</b> - allows to select default color for
+vertices.</li>
+<li><b>Color of isolines</b> - allows to select default color for
+isolines.</li>
+<li><b>Step value for spin boxes</b> - allows to define the increment
+of values set in spin boxes.</li>
+<li><b>Deflection coefficient</b> - allows to define default deflection
+coefficient for lines and surfaces. A smaller coefficient provides
+better quality of a shape in the viewer.</li>
+<li><b>Default front material</b> - allows to define default front face material.</li>
+<li><b>Default back material</b> - allows to define default back face material.</li>
+<li><b>Edges width</b> - allows to define default width of the edges.</li>
+<li><b>Isolines width</b> - allows to define default width of the isolines.</li>
+<li><b>Preview edges width</b> - allows to define width of the edges for preview.</li>
+<li><b>Measures line width</b> - allows to define lines width of measurements tools.</li>
