What does the new changes mean?

3D Earthwork

No more;

• earthwork from cross sections

• hand modification of cross sections

• slope stakes from XS and limits of construction (LoC)

• drainage Ditch Excavation (DDE) from cross sections

• Geotechnical undercuts, unsuitable material, rock layers

from cross sections

• Display Cut and Fill Values (XS view graphic only)

• Component Quantities

• Element Component Quantities

• Quantities by Named Boundary

Typical Workflow

3D Earthwork

1. Change Corridor Feature Definition to “Earthwork”

2. Create 3D Cut and Fill Volumes

3. Create Named Boundaries

Station Range

Interval

Offsets (Left and Right of Centerline)

4. Earthwork Report

5. X-1A Sheet???

13

Corridor Feature Definition – “Earthwork”

3D Earthwork

• Change Corridor Feature Definition in CMD File

• Bottom Mesh Display = True

14

15

Cut and Fill Volumes (3D)

3D Earthwork

• In Separate File, e.g. “r2635c_rdy_ear.dgn”

• OpenRoads Modeler Home Civil Analysis

Create Cut Fill Volumes

1. Select Exist Surface (Existing Ground)

2. Select Design Surface (Bottom Mesh)

3. Cut Feature Definition (Green)

4. Fill Feature Definition (Red)

Named Boundaries

3D Earthwork

OpenRoads Modeler Drawing Production Place

Named Boundary Civil Plan

1. Drawing Seed: “Earthwork”

2. Uncheck “Create Drawing” (do not create)

Earthwork Report

3D Earthwork

OpenRoads Modeler Home Civil Analysis

Quantities Report by Named Boundary

1. Named Boundary Group

2. Display Clipped Graphics Option (used to check volume,

instead of average end areas, within a named boundary).
