FREE AutoCAD add-on for creating terrain sections - Windows Freeware. With this FREE AutoCAD add-on you can create terrain sections from geodetic points(heights) in the drawing. You can also specify position of pipe(cable, road, ...) or set auxiliary marks in the section. Text settings, scale in X,Y axis, height of the reference plane and type of the terrain section can be set at start-up.

There are two ways how you can create terrain sections: 1) Terrain section from known X,Y coordinates Enter values for X,Y coordinates, specify marks position and terrain section is drawn in real time as you type values. 2) Terrain section from the drawing with geodetic heights Specify points on-screen and type 'Y' if you want to enter Y-coordinate(terrain height). You can also specify marks position or use 'Interpolate' option to calculate terrain height from two near terrain heights. Terrain section will then be created in a new drawing.
