+*********************************
+Cut a tetrahedron mesh by a plane
+*********************************
+
+MeshCut works only with MED files and produces MED files, and is a standalone program. It can be used either directly from a command shell outside SALOME, or with a GUI interface in SMESH, provided in a python plugin that needs to be installed in your SALOME application.
+
+MeshCut allows to cut a mesh constituted of linear tetrahedrons by a plane.
+The tetrahedrons intersected by the plane are cut and replaced by elements of various types, (tetrahedron, pyramid, pentahedron).

+#####################################################
+
+MeshCut is a standalone program, reading and producing med files.
+
+Syntax::
+
+ MeshCut input.med output.med resuMeshName aboveGroup belowGroup nx ny nz px py pz T
+
+where:
+
+* **input.med** = name of the original mesh file in med format
+* **output.med** = name of the result mesh file in med format
+* **resuMeshName** = name of the result mesh
+* **aboveGroup** = name of the group of volumes above the cut plane
+* **belowGroups** = name of the group of volumes below the cut plane
+* **nx ny nz** = vector normal to the cut plane
+* **px py pz** = a point of the cut plane
+* **T** = 0 < T < 1 : vertices of a tetrahedron are considered as belonging to the cut plane if their distance from the plane is inferior to L*T, where L is the mean edge size of the tetrahedron

+
+Using MeshCut inside SALOME
+###########################
+
+When the MeshCut plugin is installed, it can be found in the Mesh menu, sub-menu SMESH_plugins.
+If the plugin is not installed, the file meshcut_plugin.py is in SMESH installation in subdirectory
+*bin/salome/meshcut_plugin.py*.
+
+If there are already plugins defined in a smesh_plugins.py file, this file should be added at the end. If not, copied as
+*${HOME}/Plugins/smesh_plugins.py* or *${APPLI}/Plugins/smesh_plugins.py* or in *${PLUGINPATH}* directory.
+
+From the Mesh menu, sub-menu SMESH_plugins, choose **"MeshCut"** item
+The following dialog box will appear:
+
+.. image:: ../images/meshcut_plugin.png
+ :align: center
+
+.. centered::
+ MeshCut Plugin dialog box
+
+See above for the meaning of the parameters.
