+Offset 2D elements in mesh, submesh, group or elements from filter.
+
+*To offset all elements from mesh, sub-mesh or group:*
+
+.. |img| image:: ../images/image81.png
+
+#. In the **Modification** menu, select the **Transformations** then click *Offset* button |img| or click directly in the same button in the toolbar.
+
+ The following dialog box will appear:
+
+ .. image:: ../images/offset_mesh.png
+ :align: center
+
+ * Check the option **Select whole mesh, sub-mesh or group** if it is not set.
+ * Set the name of the mesh, sub-mesh or created group.
+ * Set the **Offset** value (negative offsets are allowed).
+ * Select **Move Elements** to offset the current mesh, **Copy Elements** to offset and duplicate them, or **Create a new mesh** to create a new mesh from the offset elements.
+
+#. Click the **Apply** or **Apply and Close** button to confirm the operation.
+
+
+*To offset all elements ids from a filter:*
+
+#. In the **Modification** menu, select the **Transformations** then click *Offset* button |img| or click directly in the same button from the toolbar.
+
+ * Uncheck the option **Select whole mesh, sub-mesh or group**.
+
+ .. image:: ../images/offset_mesh_from_filter.png
+ :align: center
+
+ * Then click on **Set_Filter** button
+
+ The dialog for filter for faces will appear:
+
+ .. image:: ../images/offset_filter_for_faces_gui.png
+ :align: center
+
+ * Define the desired criterias and then click the **Apply and Close** button to confirm the selection of elements.
+ * Set **Offset** value and mesh creation **options** as done for the first case.
+
+#. Click the **Apply** or **Apply and Close** button to confirm the operation.
