-Boolean operations on groups
-****************************
-
-In MESH you can perform some Boolean operations on groups, which belong to one and the same mesh.
-
-* :ref:`union_anchor`
-* :ref:`intersection_anchor`
-* :ref:`cut_anchor`
-
-
-
-
-.. _union_anchor:
-
-Union of groups
-###############
-
-This operation allows to create a new group in such a way that all
-mesh elements that are present in the initial groups will be added to
-the new one.
-
-*To union groups:*
-
-#. In the **Mesh** menu select the **Union Groups** item. The following dialog box will appear:
-
- .. image:: ../images/uniongroups.png
- :align: center
-
- In this dialog box you should specify the name of the resulting group and set of groups which will be united.
-
- For example, we have two groups Group1 and Group2.
- The result of their **Union** will be Group12:
-
- .. image:: ../images/image133.gif
- :align: center
-
- .. centered::
- Group1
-
- .. image:: ../images/image134.gif
- :align: center
-
- .. centered::
- Group2
-
- .. image:: ../images/image135.gif
- :align: center
-
- .. centered::
- Group12
-
-#. Click the **Apply** or **Apply and Close** button to confirm creation of the group.
-
-
-**See Also** a sample TUI Script of a :ref:`tui_union_of_groups` operation.
-
-
-.. _intersection_anchor:
-
-Intersection of groups
-######################
-
-This operation allows to create a new group in such a way that all
-mesh elements that are present in all initial groups together are added to the
-new one.
-
-*To intersect groups:*
-
-#. In the **Mesh** menu select the **Intersect Groups** item. The following dialog box will appear:
-
- .. image:: ../images/intersectgroups.png
- :align: center
-
- In this dialog box you should specify the name of the resulting group and set of groups which will be intersected.
-
- For example, we have two groups Group1 and Group2.
- The result of their **Intersection** will be Group12a:
-
- .. image:: ../images/image133.gif
- :align: center
-
- .. centered::
- Group1
-
- .. image:: ../images/image134.gif
- :align: center
-
- .. centered::
- Group2
-
- .. image:: ../images/image136.gif
- :align: center
-
- .. centered::
- Group12a
-
-#. Click the **Apply** or **Apply and Close** button to confirm creation of the group.
-
-
-**See Also** a sample TUI Script of an :ref:`tui_intersection_of_groups` operation.
-
-
-.. _cut_anchor:
-
-Cut of groups
-#############
-
-This operation allows to create a new group in such a way that all
-mesh elements that are present in the main groups but are absent in the
-tool groups are added to the new one.
-
-*To cut groups:*
-
-#. In the **Mesh** menu select the **Cut Groups** item. The following dialog box will appear:
-
- .. image:: ../images/cutgroups.png
- :align: center
-
- In this dialog box you should specify the name of the resulting group and groups which will be cut.
-
- For example, we have two groups Group1 and Group2.
- The result of their **Cut** will be Group12b:
-
- .. image:: ../images/image133.gif
- :align: center
-
- .. centered::
- Group1
-
- .. image:: ../images/image134.gif
- :align: center
-
- .. centered::
- Group2
-
- .. image:: ../images/image137.gif
- :align: center
-
- .. centered::
- Group12b
-
-#. Click the **Apply** or **Apply and Close** button to confirm creation of the group.

-**See Also** a sample TUI Script of a :ref:`tui_cut_of_groups` operation.
