4. Intersection Design

The intersection wizard was refined in this release, offering better control over geometry and the ability to handle more complex curb return profiles. It allowed engineers to dynamically update intersection designs when the intersecting roads changed.

2. Pressure Pipe Networks (Maturity)

Civil 3D 2013 introduced pressure pipes, but they were unstable. By 2015 (Release 15), the pressure network engine had matured. Users gained the ability to create fittings and appurtenances via a Part Builder that actually behaved predictably, allowing for realistic water main design without third-party plugins.

2. Pressure Pipe Networks (The Big One)

Version 15 delivered a complete overhaul of pressure pipe networks (water mains, force mains). Unlike gravity pipes (storm/sanitary), pressure pipes require fittings like elbows, tees, and valves. Civil 3D 2015 introduced:

For water utility designers, this feature single-handedly justified the upgrade.

  • Yes: You can open a 2015 DWG directly.
  • No: You cannot save it back to 2015 format once you modify corridor objects. Civil 3D uses forward-compatibility only for dynamic objects.
  • The Process: Use Export to AutoCAD (which explodes all C3D objects to 3D solids/lines) if you need to send plans back to a 2015 user.

  • Part libraries specific to ductile iron, PVC, and HDPE.
  • Automatic fitting placement based on deflection angles.
  • Depth and cover checks for clash detection.
  • Longitudinal profile editing that respects hydraulic grade lines.

For water utility designers, this feature single-handedly justified the upgrade.
