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, Main 2 5. Add Main Corridor Controls 1. 2. 3. 4. 5. Spring 2014 BL Point Control, Both Ramp. In Point Control, Horizontal Gore Slope Parametric Constraints Shoulder Width Parametric Constraints Shoulder Slopes on Ramps
