5 To produce a \b Common operation in the <b>Main Menu</b> select <b>Operations - > Boolean - > Common</b>
7 This operation cuts the common part of a list of shapes and transforms it into an independent geometrical object.
9 The \b Result will be a \b GEOM_Object.
11 <b>TUI Command:</b> <em>geompy.MakeCommonList(theShapesList, checkSelfInte)</em>\n
12 <b>Arguments:</b> Name + a list of shapes + an optional flag for self-intersection check.\n
13 <b>Advanced option:</b>
14 \ref restore_presentation_parameters_page "Set presentation parameters and sub-shapes from arguments".

18 \note This algorithm doesn't find all types of self-intersections. It is tuned
19 to detect vertex/vertex, vertex/edge, edge/edge, vertex/face and edge/face
20 intersections. Face/face intersections detection is switched off as it
21 is a time-consuming operation that gives an impact on performance. To find
22 all self-intersections please use \ref check_self_intersections_page
23 "Detect Self-intersection tool".
25 For a particular case with two shapes for the Common operation there is the following TUI command:
27 <b>TUI Command:</b> <em>geompy.MakeCommon(s1, s2, checkSelfInte)</em>\n
28 <b>Arguments:</b> Name + 2 shapes + an optional flag for self-intersection check.

36 Our <b>TUI Scripts</b> provide you with useful examples of the use of
37 \ref tui_common "Boolean Operations".
41 For a detailed description of the Boolean operations please refer to

43 It provides a general review of the Partition and Boolean
44 operations algorithms, describes the usage methodology and highlights
45 major limitations of these operations.
