-Removing nodes
-##############
-
-**To remove a node:**
-
-.. |rmn| image:: ../images/remove_nodes_icon.png
-
-#. Select your mesh in the Object Browser or in the 3D viewer.
-#. From the **Modification** menu choose **Remove** and from the associated submenu select the **Nodes**, or just click *"Remove nodes"* button |rmn| in the toolbar.
- The following dialog box will appear:
-
- .. image:: ../images/removenodes.png
- :align: center
-
-
- In this dialog box you can specify one or several nodes:
-
- * choose mesh nodes with the mouse in the 3D Viewer. It is possible to select a whole area with a mouse frame; or
- * input the node IDs directly in **Node IDs** field. The selected nodes will be highlighted in the viewer; or
- * apply Filters. **Set filter** button allows to apply a filter to the selection of nodes. See more about filters in the :ref:`selection_filter_library_page` page.
-
-#. Click **Apply** or **Apply and Close** to confirm deletion of the specified nodes.
-
-.. note::
- Be careful while removing nodes because if you remove a definite node of your mesh all adjacent elements will be also deleted.

-Removing node with reconnection
-###############################
-
-This operation removes a node and changes surrounding faces in order to cover a hole appearing in the mesh. This operation applies to 2D triangle mesh only.

-
-**To remove a node:**
-
-.. |rmnr| image:: ../images/remove_node_reconnection_icon.png
-
-#. Select your mesh in the Object Browser or in the 3D viewer.
-#. From the **Modification** menu choose **Remove** and from the associated submenu select the **Node with reconnection**, or just click *"Remove node with reconnection"* button |rmnr| in the toolbar.
- The following dialog box will appear:
-
- .. image:: ../images/remove_node_reconnection_dlg.png
- :align: center
-
-
- In this dialog box you can specify one node to remove:
-
- * choose a mesh node with the mouse in the 3D Viewer or
- * input the node ID directly in **ID** field. The selected node will be highlighted in the viewer.
-
- Activate **Preview** to see how faces will change.
-
-#. Click **Apply** or **Apply and Close** to confirm deletion of the specified node.

-Removing orphan nodes
-#####################
-
-There is a quick way to remove all orphan (free) nodes.
-
-*To remove orphan nodes:*
-
-.. |rmon| image:: ../images/remove_orphan_nodes_icon.png
-
-#. Select your mesh in the Object Browser or in the 3D viewer.
-#. From the **Modification** menu choose **Remove** and from the associated submenu select **Orphan Nodes**, or just click *"Remove orphan nodes"* button |rmon| in the toolbar.
- The following Warning message box will appear:
-
- .. image:: ../images/removeorphannodes.png
- :align: center
-
-#. Confirm nodes removal by pressing "Yes" button.
-
-
-.. _removing_elements_anchor:
-
-Removing elements
-#################
-
-*To remove an element:*
-
-.. |rme| image:: ../images/remove_elements_icon.png
-
-#. Select your mesh in the Object Browser or in the 3D viewer.
-#. From the **Modification** menu choose **Remove** and from the associated submenu select the **Elements**, or just click *"Remove elements"* button |rme| in the toolbar.
-
- The following dialog box will appear:
-
- .. image:: ../images/removeelements.png
- :align: center
-
- In this dialog box you can specify one or several elements:
-
- * choose mesh elements with the mouse in the 3D Viewer. It is possible to select a whole area with a mouse frame; or
- * input the element IDs directly in **ID Elements** field. The selected elements will be highlighted in the viewer; or
- * apply Filters. **Set filter** button allows to apply a filter to the selection of elements. See more about filters in the :ref:`selection_filter_library_page` page.
-
-#. Click **Apply** or **Apply and Close** to confirm deletion of the specified elements.

-
-Clearing Mesh Data
-##################
-
-*To remove all nodes and all types of cells in your mesh at once:*
-
-.. |clr| image:: ../images/mesh_clear.png
-
-#. Select your mesh in the Object Browser or in the 3D viewer.
-#. From the **Modification** menu choose **Remove** and from the associated submenu select the **Clear Mesh Data**, or just click *"Clear Mesh Data"* button |clr| in the toolbar. You can also right-click on the mesh in the Object Browser and select **Clear Mesh Data** in the pop-up menu.
-
-.. note::
- This command works in a different way in different situations:
- * if the mesh is computed on a geometry, then *Clear Mesh Data* removes all elements and nodes.
- * if the mesh is not based on a geometry (imported, compound, created from scratch etc.), then *Clear Mesh Data* removes only the elements and nodes computed by algorithms. If no such elements or nodes have been created, can remove nothing.

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