 Interpolation
 =============
 
+Interpolation feature creates a curve (edge) using vertices already existing in other objects.
+
+To create an interpolation in the active part:
+
+#. select in the Main Menu *Build - > Interpolation* item  or
+#. click **Interpolation** button in the toolbar
+
+.. image:: images/feature_interpolation.png
+  :align: center
+
+.. centered::
+  **Interpolation** button
+
+The following property panel will be opened:
 
 .. image:: images/Interpolation.png
   :align: center
 
 .. centered::
   Create an interpolation
+
+Select one or several vertices or points in the viewer.
+
+- **Closed** makes the interpolation curve closed.
+
+- **Reorder** reorders the selected points to minimize the length of curve.
+
+- **Tangents** makes start and end of the curve tangent to the selected edges. The user has to select start and end edges in the corresponding fields.
+
+**Apply** button creates an interpolation.
+
+**Cancel** button cancels the operation. 
+
+**TUI Command**:
+
+- *model.addInterpolation(Part_doc, Points, IsClosed, IsReordered)*.
+
+**Arguments**:   Part document + list of points + is closed + is reordered.
+
+- *model.addInterpolation(Part_doc, Points, StartEdge, EndEdge, IsClosed, IsReordered)*.
+
+**Arguments**:   Part document + list of points + start edge + end edge + is closed + is reordered.
+
+Result
+""""""
+
+The result of the operation will be a curve created from the selected shapes:

+.. image:: images/CreateInterpolation.png
+  :align: center
+
+.. centered::
+  Result of the operation.
+
+**See Also** a sample TUI Script of :ref:`tui_create_interpolation` operation.
