+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
+The choices available 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 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):
+Note: "flat" contents means that top-level simple-type sub-shapes are extracted from

+
+Let us take, for example, compound C1 that contains solid S1 and another compound C2 that
+contains solids S2 and S3 (see the 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.

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.
