Corridors, grading and drainage

1. 1. Assemblies and corridors

   A corridor sweeps a typical cross-section (the assembly) along an alignment and profile to create a 3D road. It’s the heart of road design in Civil 3D.

   • • Build an assembly from subassemblies
   • • Create a corridor and control frequency
   • • Use targets for widening and daylight

2. 2. Grading and earthworks volumes

   Site grading shapes the ground for buildings, car parks and drainage. Learn to model graded surfaces with feature lines and calculate cut and fill.

   • • Model pads and slopes with feature lines
   • • Create grading objects to target surfaces
   • • Calculate cut and fill with volume surfaces

   20 min

3. 3. Pipe networks

   Pipe networks model stormwater and sewer systems: pipes and structures that know their sizes, slopes and inverts, and appear in plan and profile together.

   • • Set up a parts list
   • • Lay out a gravity network with pipes and structures
   • • Show the network in profile and edit inverts
