\anchor pref_settings <h2>Settings</h2>

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.

To redefine any color click on the corresponding line to access to
the <b>Select Color</b> dialog box.

<ul>
<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>Top level color</b> - allows to select default color for objects which 
were brought to the viewer foreground.</li>
<li><b>Top level display mode</b> - allows to select default top level display mode between:</li>
<ul>
<li><b>Show additional wireframe actor</b> - allows to have the shading actor at its usual 
place (in the back) and add the additional wireframe actor in the viewer foreground.</li>
<li><b>Keep current display mode</b> - allows to use current display mode of object.</li>
<li><b>Wireframe</b> - allows to switch display mode to wireframe mode after 
"top-level" operation.</li>
<li><b>Shading</b> - allows to switch display mode to shading mode after 
"top-level" operation.</li>

"top-level" operation.</li>
</ul>
<li><b>Transparency</b> - allows to define default transparency value.</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>

predefined materials.</li>
<li><b>Default material</b> - allows to define default material.</li>
<li><b>Subshapes color for editing a group</b> - allows to select default color for subshapes in a group.</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>
<li><b>Step value for spin boxes</b> - allows to define the increment
of values set in spin boxes.</li>
<li><b>Automatic bring to front</b> - when the option is on, the objects selected by the user automatically become "top-level".</li>

</ul>
</ul>

<ul>
<li><b>Dimensions (Measurements)</b></li>
<ul>
<li><b>Color</b> - allows to define color for persistent dimension presentations.</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>
</ul>
</ul>

<ul>
<li><b>Number of isolines</b> - allows to specify the number of isolines along <b>Along U</b> and <b>Along V</b> coordinate axes. They are shown on each selected face. For example:
