|
To \b Explode an object into sub-shapes, in the <b>Main Menu</b>
|
|
select <b>New Entity > Explode</b>. This operation opens the
|
|
<b>Sub Shapes Selection</b> dialog box.
|
|
|

|
|
|
|
To create a list of sub-shapes (vertices, edges, wires etc.) of the
|
|
given shape using the \b Explode operation, you need to define the <b>Main
|
|
Object</b>, which will be exploded and the <b>Type of Sub-shapes</b> you wish to
|
|
obtain from it.
|
|
|
|
The \b Result of the operation will be a List of \b GEOM_Objects
|
|
(vertexes, edges, wires, faces, shells or solids).
|
|
|
|
Available choices in the <b>Sub Shapes Type</b> combo box depend on the type
|
|
of selected <b>Main Object</b>:
|
|
- \b Compound: to extract compounds;
|
|
- \b Compsolid: to extract compsolids;
|
|
- \b Solid: to extract solids;
|
|
- \b Shell: to extract shells;
|
|
- \b Face: to extract faces;
|
|
- \b Wire: to extract wires;
|
|
- \b Edge: to extract edges;
|
|
- \b Vertex: to extract vertices;
|
|
- \b Shape: to extract top-level contents of the compound shape;
|
|
- \b Flat: to extract "flat" contents of the compound shape.
|
|
|
|
Note: "flat" contents means top-level simple-type sub-shapes extracted from
|
|
the compound object recursively (i.e. there is no compounds in the result).
|
|
For example, if a compound C1 contains a solid S1 and another compound C2 that
|
|
contains solids S2 and S3 (see picture below):
|
|
- Explode operation with \b Shape type given as parameter will return S1 and C2;
|
|
- Explode operation with \b Flat type given as parameter will return S1, S2 and S3.

|
Switching on <b>Select Sub-shapes</b> check box allows manual selection of sub-shapes
|
|
to be extracted from the main object. In this mode the user can select sub-shapes
|
|
directly in 3D viewer.
|
|
|
|
Using <b>TUI Commands</b> you can perform this operation in a
|
|
variety of ways:
|
|
- <em>geompy.ExtractShapes(Shape, Type, isSorted)</em> explodes a
|
|
Shape into sub-shapes of a given Type and returns a List of sub-shapes.
|
|
This method does not return the Shape itself if it matches the
|
|
Type.
|
|
- <em>geompy.SubShapeAll(Shape, Type)</em> explodes a Shape on
|
|
sub-shapes of a given Type and returns a List of sub-shapes.
|
|
- <em>geompy.SubShapeAllIDs(Shape, Type)</em> explodes a Shape on
|
|
sub-shapes of a given Type and returns a List of IDs of
|
|
sub-shapes.
|
|
- <em>geompy.SubShapeAllSortedCentres(Shape, Type)</em> explodes a
|
|
shape on sub-shapes of a given type and sorts them taking into account
|
|
their gravity centers, to provide stable order of sub-shapes.
|
|
It returns a list of sub-shapes.
|
|
- <em>geompy.SubShapeAllSortedCentresIDs(Shape, Type)</em> explodes
|
|
a shape on sub-shapes of a given type and sorts them taking into
|
|
account their gravity centers, to provide stable order of sub-shapes.
|
|
It returns a List of IDs of sub-shapes.
|
|
- <em>geompy.SubShape(Shape, Type, ListOfInd)</em> allows to obtain
|
|
a compound of sub-shapes of the Shape, selected by they indices in a
|
|
list of all sub-shapes of the given Type. Each index is in the range
|
|
[1, Nb_Sub-Shapes_Of_Given_Type].
|
|
- <em>geompy.SubShapeSortedCentres(Shape, Type, ListOfInd)</em>
|
|
allows to obtain a compound of sub-shapes of the Shape, selected by
|
|
they indices in sorted list of all sub-shapes of the given Type. Each
|
|
index is in the range [1, Nb_Sub-Shapes_Of_Given_Type]
|
|
|
|
<b>Arguments: </b>1 SHAPE + 1 type of SubShape.
|
|
|
