/*! \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. \image html pref15.png \par 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>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>Show predefined materials in popup menu</b> - allows to customize the displaying of popup menu with list of 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>Automatic bring to front</b> - when option is ON: the objects selected by the user will be automatically made "top-level".</li> </ul> </ul> <ul> <li><b>Number of isolines</b></li> - this submenu allows to specify the number of isolines along the axes of coordinates: <ul> <li><b>Along U</b> <li><b>Along V</b> </ul> </ul> <ul> <li><b>Input fields precision</b></li> <ul> <li><b>Length precision</b> - allows to ajust input precision of coordinates and dimensions.</li> <li><b>Angular precision</b> - allows to ajust input precision of angles.</li> <li><b>Length tolerance precision</b> - allows to ajust input precision of tolerance of coordinates and dimensions.</li> <li><b>Angular tolerance precision</b> - allows to ajust input precision of tolerance of angles.</li> <li><b>Weight precision</b> - allows to ajust input precision of weight and mass.</li> <li><b>Density precision</b> - allows to ajust input precision of density.</li> <li><b>Parametric precision</b> - allows to ajust input precision of parametric values.</li> <li><b>Parametric tolerance precision</b> - allows to ajust input precision of tolerance in parametric space.</li> </ul> </ul> <ul> <li><b>Marker of Points</b></li> <ul> <li><b>Type</b> - allows to select the symbol for representation of points (cross, asterisk, etc.).</li> <li><b>Size</b> - allows to define the size of the marker from 1 (smallest) to 7 (largest).</li> </ul> </ul> <ul> <li><b>Origin and base vectors</b></li> <ul> <li><b>Length of base vectors</b> - allows to define the length of base vectors.</li> <li><b>Auto create</b> - allows to automatically create a point of origin and three base vectors of the rectangular coordinate system immediately after the module activation.</li> </ul> </ul> <ul> <li><b>Scalar bar for field presentation</b></li> <ul> <li><b>X position</b> - allows to define the parametric X position of the scalar bar.</li> <li><b>Y position</b> - allows to define the parametric Y position of the scalar bar.</li> <li><b>Width</b> - allows to define the parametric width of the scalar bar.</li> <li><b>Height</b> - allows to define the parametric height of the scalar bar.</li> <li><b>Text height</b> - allows to define the font height of the scalar bar labels.</li> <li><b>Number of intervals</b> - allows to define the number of scalar bar intervals.</li> </ul> </ul> <ul> <li><b>Operations</b></li> <ul> <li><b>Preview</b> - allows to customize the displaying preview by default.</li> </ul> </ul> */
