6.3 Workpiece Description
Integrating overlay elements
You describe contour trains in the same way as a finished part contour
and superimpose them. Alternatively, you can use the following
standard overlay elements (see “Overlay Elements” on page 418):
 Circular arc
 Wedge
 Pontoon
These elements superimpose existing linear or circular supporting
contour elements. Integrated overlay elements are part of the contour.
Integrating a contour train:
Select “Program > Load > Contour train”. Select and load the file.
Press the ESC key to return to the main menu.
Select “Workpiece > Finished part > Form > Contour
overlap > Contour.”
