Urban Design—Advanced Corridor Modeling with AutoCAD Civil 3D and Subassembly Composer

Urban corridor models can often be very restraining, and obtaining additional right of way (ROW) can be both costly and difficult. This instructional demo will utilize AutoCAD Civil 3D software and Subassembly Composer using an example project that has limited ROW while widening both the roadway and adjacent sidewalks. The demonstration will show how the corridor model was developed using auxiliary corridors to define proposed improvements. Custom subassemblies were created to model curb ramps, stairs, and curb transitions to meet criteria and constraints. Upon completion of this class, attendees will evaluate an approach to designing roadways with auxiliary corridor models and creating custom subassemblies to further define the actual roadway elements that will be constructed. Attendees will also be able to create a visualization of the urban corridor to help the public and reviewers understand the design.
