/*! \page common_operation_page Common \b Common operation cuts the common part of a list of shapes and transforms it into an independent geometrical object. To produce it, select in the main menu <b>Operations - > Boolean - > Common</b>. \image html bool2.png "Common dialog" In this dialog: - Input or accept the default \b Name of the resulting shape. - Click the arrow button and select in the Object Browser or in the Viewer the <b>Objects</b> the common part which of should be found. - Activate the corresponding check-box if you wish to <b> Detect Self-intersections </b> - Activate \ref restore_presentation_parameters_page "Advanced options" if required. - Press "Apply" or "Apply & Close" button to get the result (GEOM_Object). \note This algorithm does not find all types of self-intersections. It is tuned to detect vertex/vertex, vertex/edge, edge/edge, vertex/face and edge/face intersections. Face/face intersections detection is switched off as it is a time-consuming operation that gives an impact on performance. To find all self-intersections use \ref check_self_intersections_page "Detect Self-intersection tool". This operation can be performed using a <b>TUI Command:</b> <em>geompy.MakeCommonList(theShapesList, checkSelfInte)</em> <b>Arguments:</b> Name + a list of shapes + an optional flag for self-intersection check. There is also a special <b>TUI Command</b> for the Common operation on two shapes : <em>geompy.MakeCommon(s1, s2, checkSelfInte)</em> <b>Arguments:</b> Name + 2 shapes + an optional flag for self-intersection check. <b>Example:</b> \image html fusesn1.png "The initial shapes" \image html commonsn.png "The resulting object" Our <b>TUI Scripts</b> provide you with useful examples of the use of \ref tui_common "Boolean Operations". <b> More details </b> Please, refer to <a href="SALOME_BOA_PA.pdf">this document</a> for a detailed description of Boolean operations. It provides a general review of the Partition and Boolean operations algorithms, describes the usage methodology and highlights major limitations of these operations. */
