Detail(site) MODELING
GENERAL WORKFLOW STEPS:
1. Layout the Baseline Horizontal Geometry
2. Use the Ramp Terminal Civil Cell or build Planimetrics
3. Use Vertical Alignment tools:
a)
b)
c)
d)
Project Slope to Element; PGL to EOP, EOP to BL Ramp
Place Line at Gore End
Construct Reverse Transition Ramp profile
Complex Profile by Elements, Check Design Standards
4. Drop Templates; Main w/ Gore, Ramp, Main2
5. Add Main Corridor Controls
