Use this option to assign elevations to the break points by interpolating.

The upper list area lists the break point number, coordinates, and chainage.


Note: The function can be used to obtain calculated heights for the intermediary points. If elevations are defined for 3 or more points, first interpolate heights between the first two key break points and then between the next two points, and so on.

Tip: Instead of repeating the interpolation for a different section of the line, manually assign the elevations for all the break points, and use the function 'Height Interpolation' to interpolate heights for all the points.

For further details, refer to Height Interpolation.
