5 \b Section operation creates an edge or a wire representing the intersection of surfaces of two shapes.
7 To produce it, select in the main menu <b>Operations - > Boolean - > Section</b>
9 \image html neo-section.png "Section dialog"
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 intersecting <b>Objects</b>.
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 (EDGE or WIRE).
18 \note This algorithm does not 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 use \ref check_self_intersections_page
23 "Detect Self-intersection tool".
25 This operation can be performed using a <b>TUI Command:</b>
27 <em>geompy.MakeSection(s1, s2, checkSelfInte)</em>
29 <b>Arguments:</b> Name + 2 shapes + an optional flag for self-intersection check.

42 Please refer to <a href="SALOME_BOA_PA.pdf">this document</a> for a detailed description of Boolean operations.
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.
