+Only MED format supports all types of elements that can be created in the module. If you export a mesh or group that includes elements of types that are not supported by chosen format, you will be warned about that.

+* **Z tolerance** field if enabled specifies distance of nodes from the XOY plane below which the nodes snap to this plane. A default value can be set in :ref:`Preferences <medexport_z_tolerance_pref>`.
 * **Automatically create groups** check-box specifies whether to create groups of all mesh entities of available dimensions or not. The created groups have names like "Group_On_All_Nodes", "Group_On_All_Faces", etc. A default state of this check-box can be set in :ref:`Preferences <export_auto_groups_pref>`.
 * **Automatically define space dimension** check-box specifies whether to define space dimension for export by mesh configuration or not. Usually the mesh is exported as a mesh in 3D space, just as it is in Mesh module. The mesh can be exported as a mesh of a lower dimension in the following cases, provided that this check-box is checked:
 
   * **1D**: if all mesh nodes lie on OX coordinate axis. 
   * **2D**: if all mesh nodes lie in XOY coordinate plane.
