5 The Interpolation feature creates curve (wire) using already existing vertices in other objects.
7 To create interpolation in the active part:
9 #. select in the Main Menu *Build - > Interpolation* item or
10 #. click **Interpolation** button in the toolbar
12 .. image:: images/feature_interpolation.png
16 **Interpolation** button
18 The following property panel will be opened:
20 .. image:: images/Interpolation.png
24 Create an interpolation
26 Select one or several vertices or points in a viewer.
28 - **Closed** makes the interpolation curve closed.
30 - **Reorder** reorders selected points to minimize length of the curve.
32 - **Tangents** makes start and end of the curve tangent to selected edges. User has to select edges for start and end in corresponded fields.
34 **Apply** button creates an interpolation.
36 **Cancel** button cancels operation.
40 - *model.addInterpolation(Part_doc, Points, IsClosed, IsReordered)*.
42 **Arguments**: Part document + list of points + is closed + is reordered.
44 - *model.addInterpolation(Part_doc, Points, StartEdge, EndEdge, IsClosed, IsReordered)*.
46 **Arguments**: Part document + list of points + start edge + end edge + is closed + is reordered.
51 The result of the operation will be a curve created from selected shapes:
