major limitations of these operations.
You can use the following boolean operations for construction of more
You can use advanced TUI commands performing these operations
independently from each other:
\par
-<em>geompy.MakeFuseList(theShapesList)</em>, where \em theShapesList is
+<em>geompy.MakeFuseList(theShapesList, checkSelfInte, rmExtraEdges)</em>, where \em theShapesList is
the list of shapes for Fuse operation;
\par
-<em>geompy.MakeCommonList(theShapesList)</em>, where \em theShapesList is
+<em>geompy.MakeCommonList(theShapesList, checkSelfInte)</em>, where \em theShapesList is
the list of shapes for Common operation;
\par
-<em>geompy.MakeCutList(theMainShape, theShapesList)</em>, where \em
+<em>geompy.MakeCutList(theMainShape, theShapesList, checkSelfInte)</em>, where \em
theMainShape is the object of the operation and \em theShapesList is
the list of tools for Cut operation;
\par
-<em>geompy.MakeSection(Shape1, Shape2)</em>, where \em Shape1 is the first
+<em>geompy.MakeSection(Shape1, Shape2, checkSelfInte)</em>, where \em Shape1 is the first
argument and \em Shape2 is the second argument of Section operation;
operations, which can be used alongside with separate commands for each
operation.
\par
-<em>geompy.MakeBoolean(Shape1, Shape2, Operation),</em> where \em
+<em>geompy.MakeBoolean(Shape1, Shape2, Operation, checkSelfInte),</em> where \em
Shape1 is the first argument and \em Shape2 is the second argument of
-Boolean operation, \em Operation is a type of the Boolean operation (1
+a Boolean operation, \em Operation is the type of a Boolean operation (1
— Common, 2 — Cut, 3 — Fuse, 4 — Section).
Besides, you can use advanced TUI commands performing these operations
independently from each other:
\par
-<em>geompy.MakeFuse(Shape1, Shape2)</em>, where \em Shape1 is the first
+<em>geompy.MakeFuse(Shape1, Shape2, checkSelfInte, rmExtraEdges)</em>, where \em Shape1 is the first
argument and \em Shape2 is the second argument of Fuse operation;
\par
-<em>geompy.MakeCommon(Shape1, Shape2)</em>, where \em Shape1 is the first
+<em>geompy.MakeCommon(Shape1, Shape2, checkSelfInte)</em>, where \em Shape1 is the first
argument and \em Shape2 is the second argument of Common operation;
\par
-<em>geompy.MakeCut(Shape1, Shape2)</em>, where \em Shape1 is the first
+<em>geompy.MakeCut(Shape1, Shape2, checkSelfInte)</em>, where \em Shape1 is the first
argument and \em Shape2 is the second argument of Cut operation;
+The flag \em checkSelfInte indicates whether the arguments should be checked for
+self-intersection prior to an operation. Its default value is \em False, which
+means that there is no need to check it. This option is provided to ensure that
+an operation is performed on not self-intersected shapes as they are
+not valid for boolean operations.
+
+\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".
+
+The flag \em rmExtraEdges is used for \em MakeFuseList and \em MakeFuse
+operations only. It indicates if Remove Extra Edges operation should be
+performed during the operation. Its default value is \em False, which
+means that there is no need to do it.
+
+\note \em rmExtraEdges is not available for \em MakeBoolean call with
+ operation type 3 (Fuse). \em MakeBoolean operation doesn't perform
+ Remove Extra Edges. So the call <em>geompy.MakeBoolean(Shape1, Shape2,
+ 3, checkSelfInte)</em> is equivalent to <em>geompy.MakeFuse(Shape1,
+ Shape2, checkSelfInte, False)</em>.
