This tool allows one to change the height of any vertex on the polyline or of the whole polyline. The command has three different operating modes:
Polyline Vertex: The program requests the polyline’s vertex and then its height may be entered directly or by interpolating between the previous and the next vertices.
Interpolate: The program requests two of the polyline’s vertices and then the program automatically interpolates the height of all the vertices to be found between the two vertices selected.
Whole Polyline: The program requests a polyline and a height and then all the polyline’s vertices are raised to the height entered.
