\page using_boolean_operations_page Boolean Operations
|
|
|
|
For a detailed description of Boolean operations refer to
|
|
<a href="SALOME_BOA_PA.pdf">this document</a>.
|
|
It provides a general review of the Partition and Boolean
|
|
operations algorithms, describes the usage methodology and highlights
|
|
major limitations of these operations.
|
|
|
|
You can use the following boolean operations for construction of more
|
|
complex geometrical objects (2D & 3D elements):
|
|
|
|
<ul>
|
|
<li>\subpage fuse_operation_page "Fuse" - creates a shape from a list of shapes.</li>
|
|
<li>\subpage common_operation_page "Common" - transforms the common part
|
|
of a list of objects into an independent object.</li>
|
|
<li>\subpage cut_operation_page "Cut" - cuts one shape with
|
|
a list of others. </li>
|
|
<li>\subpage section_opeartion_page "Intersection" - performs an intersection between two shapes.</li>
|
|
</ul>
|
|
|
|
You can use advanced TUI commands performing these operations
|
|
independently from each other:
|
|
\par
|
|
<em>geompy.MakeFuseList(theShapesList, checkSelfInte, rmExtraEdges)</em>, where \em theShapesList is
|
|
the list of shapes for Fuse operation;
|
|
\par
|
|
<em>geompy.MakeCommonList(theShapesList, checkSelfInte)</em>, where \em theShapesList is
|
|
the list of shapes for Common operation;
|
|
\par
|
|
<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, checkSelfInte)</em>, where \em Shape1 is the first
|
|
argument and \em Shape2 is the second argument of Intersection operation;
|
|
|
|
|
|
There are several TUI commands that can be used to perform boolean operations
|
|
with only two arguments. There is a general TUI command covering these
|
|
operations, which can be used alongside with separate commands for each
|
|
operation.
|
|
\par
|
|
<em>geompy.MakeBoolean(Shape1, Shape2, Operation, checkSelfInte),</em> where \em
|
|
Shape1 is the first argument and \em Shape2 is the second argument of
|
|
a Boolean operation, \em Operation is the type of a Boolean operation (1
|
|
— Common, 2 — Cut, 3 — Fuse, 4 — Intersection).
|
|
|
|
|
|
Besides, you can use advanced TUI commands performing these operations
|
|
independently from each other:
|
|
\par
|
|
<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, 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, 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>.
