5 \b Common operation cuts the common part of a list of shapes and transforms it into an independent geometrical object.
7 To produce it, select in the main menu <b>Operations - > Boolean - > Common</b>.

12 - Input or accept the default \b Name of the resulting shape.
13 - 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.
14 - Activate the corresponding check-box if you wish to <b> Detect Self-intersections </b>
15 - Activate \ref restore_presentation_parameters_page "Advanced options" if required.
16 - Press "Apply" or "Apply & Close" button to get the result (GEOM_Object).
19 \note This algorithm does not find all types of self-intersections. It is tuned
20 to detect vertex/vertex, vertex/edge, edge/edge, vertex/face and edge/face
21 intersections. Face/face intersections detection is switched off as it
22 is a time-consuming operation that gives an impact on performance. To find
23 all self-intersections use \ref check_self_intersections_page
24 "Detect Self-intersection tool".
27 This operation can be performed using a <b>TUI Command:</b>
29 <em>geompy.MakeCommonList(theShapesList, checkSelfInte)</em>
31 <b>Arguments:</b> Name + a list of shapes + an optional flag for self-intersection check.
33 There is also a special <b>TUI Command</b> for the Common operation on two shapes :
35 <em>geompy.MakeCommon(s1, s2, checkSelfInte)</em>
37 <b>Arguments:</b> Name + 2 shapes + an optional flag for self-intersection check.

50 Please, refer to <a href="SALOME_BOA_PA.pdf">this document</a> for a detailed description of Boolean operations.
51 It provides a general review of the Partition and Boolean
52 operations algorithms, describes the usage methodology and highlights
53 major limitations of these operations.
