ADHOC DESCRIPTIONS

V-Ditch Option 1. A fixed slope at a fixed distance from Roadway A. Roadway B ties to that ditch bottom with a straight-line tie.

Applicable Adhocs:
Design Side (L or R) - Choose which side to use for “Roadway A”, Left (L) or Right (R) roadway.
Design Option Number - Use 1 for Option 1
Fixed Distance - Distance measured in the horizontal direction from Roadway A to end the fixed slope.
Fixed Slope - Slope value in a Rise:Run format used to draw the Roadway A side of the V Ditch.

V-Ditch Option 2. A fixed slope to a point located by a line in dgn (Median Designator Line) from Roadway A. Roadway B ties to that ditch bottom with a straight-line tie. The median designator controls the horizontal location of the bottom of the V Ditch.

Applicable Adhocs:
Design Side (L or R) - Choose which side to use for “Roadway A”, Left (L) or Right (R) roadway.
Design Option Number - Use 2 for Option 2
Fixed Slope - Slope value in a Rise:Run format used to draw the Roadway A side of the V Ditch.

V-Ditch Option 3. A fixed slope to an elevation (special ditch profile) from Roadway A. Roadway B ties to that ditch bottom with a straight-line tie.

Applicable Adhocs:
Design Side (L or R) - Choose which side to use for “Roadway A”, Left (L) or Right (R) roadway.
Design Option Number - Use 3 for Option 3
Special Profile Name - Name of profile used to set the elevation of the bottom of the V Ditch.
Fixed Slope - Slope value in a Rise:Run format used to draw the Roadway A side of the V Ditch.

V-Ditch Option 4. A slope at a fixed distance to an elevation (special ditch profile) for Roadway A. Roadway B ties to that ditch bottom with a straight-line tie.

Applicable Adhocs:
Design Side (L or R) - Choose which side to use for “Roadway A”, Left (L) or Right (R) roadway.
Design Option Number - Use 4 for Option 4
Special Profile Name - Name of profile used to set the elevation of the bottom of the V Ditch.
Fixed Distance - Distance measured in the horizontal direction from Roadway A to the special profile elevation.

V-Ditch Option 5. A slope to a point located by a line in dgn (Median Designator Line) to an elevation (special ditch profile) from Roadway A. Roadway B ties to that ditch bottom with a straight-line tie.

Applicable Adhocs:
Design Side (L or R) - Choose which side to use for “Roadway A”, Left (L) or Right (R) roadway.
Design Option Number - Use 5 for Option 5
Special Profile Name - Name of profile used to set the elevation of the bottom of the V Ditch.
