\page common_operation_page Common
-\n To produce a \b Common operation in the Main Menu select Operations - > Boolean - > Common
+\b Common operation cuts the common part of a list of shapes and transforms it into an independent geometrical object.
-\n This operation cuts the common part of two shapes and transforms it into an independent geometrical object.
+To produce it, select in the main menu Operations - > Boolean - > Common.
-\n The \b Result will be any \b GEOM_Object.
-\n TUI Command: geompy.MakeCommon(s1, s2)
-\n Arguments: Name + 2 shapes.
-\n Advanced option:
- \ref restore_presentation_parameters_page "Set presentation parameters and subshapes from arguments".
+\image html bool2.png "Common dialog"
-\image html bool2.png
+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 Objects the common part which of should be found.
+- Activate the corresponding check-box if you wish to Detect Self-intersections
+- Activate \ref restore_presentation_parameters_page "Advanced options" if required.
+- Press "Apply" or "Apply & Close" button to get the result (GEOM_Object).
-\n Example:
+
+\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 TUI Command:
+
+geompy.MakeCommonList(theShapesList, checkSelfInte)
+
+Arguments: Name + a list of shapes + an optional flag for self-intersection check.
+
+There is also a special TUI Command for the Common operation on two shapes :
+
+geompy.MakeCommon(s1, s2, checkSelfInte)
+
+Arguments: Name + 2 shapes + an optional flag for self-intersection check.
+
+Example:

Our TUI Scripts provide you with useful examples of the use of
\ref tui_common "Boolean Operations".

+Please, refer to this document 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.
