This component creates a flat bottom or V bottom ditch.
This component will vertically tie the bottom inside of the ditch to a feature. The inside slope (DitchInSlope) is maintained.
Widen to the right of way offset. Slope stake is at ROW offset. Steepen slope if ditch is too deep.
Outside of ditch, useful when an alignment is along a ditch bottom.
This component will create a trench with a berm.
Conditionally creates a ditch. It checks to see if it is required using a probe. If the end of the probe is below ground the ditch is formed.
This component will attach a ditch component to a feature horizontally and vertically.
Maintains user defined slopes inside the ROW. If the ditch is too deep, another slope is used to grade beyond the ROW.
Cut into merged surface. The cut depth is measured from the attachent point. Usually placed before other components.
Simple trench. Can be used to widen/deepen existing trench.
Rural road with 1 raised layer of surfacing above a base layer.
Widen to the right of way offset. Grade out beyond ROW if ditch is too deep.
This component will create a notch. A perpendicular is dropped to the merged surface then a notch is created. It closes to the merged surface.
Subcut below sub-grade. Place in template after all other components.
