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

Model Based Quantities Methods
3D Earthwork
11
• 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

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)

OpenRoads Modeler Drawing Production Place
Named Boundary Civil Plan
1. Drawing Seed: “Earthwork”
2. Uncheck “Create Drawing” (do not create)

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).
