Grade Between Markers

Smooths the gradient profile of a section of track defined by two markers. Nodes with Locked Elevation can be used to establish the elevation of known fixed points.

Grade Between Markers is just a linear interpolation, i.e. it adjusts the elevation of the unlocked nodes to produce a series of straight-line sections on the gradient profile, with sharp changes of slope at the locked nodes.
