Pipe Runs

  • Branch fittings can be added at intersections of pipe runs in the same pressure network.
  • Snapping - turn OFF
    • “Since the connection between fittings and pipes often provides a little flexibility with an allowed deflection, you could turn Snapping off. If you turn off Snapping, but leave Visibility turned on then this will allow you to draw close to an allowed bend angle but not force the exact angle.” (Autodesk University - Rediscover Pressure Pipes in Civil 3D 2021 with new path-based workflows by Charlie Ogden, p. 9, charlie.ogden@autodesk.com)

Warnings

Profiles

  • Problem - change the EG and FG profile style, but not changing?
  • Solution - Profile Data Tab has a layer option

Label FG Profile Grade Breaks

  • Create a new C3D Profile view label style
    • LCU-PV-GB
    • LCU Profile View Grade Break

Connect Pipes and Manholes

  • Problem - pipes on top of manhole.
  • Solution - think this means the pipes are NOT connected to the manhole, solution is to manually grip edit the pipe and then when the manhole glyph appears release so it connects.
  • Connect Pipes and manholes

Workflow - Pressure Pipe

  • 1. assign Pressure Network Catalog used for the Parts List
    • Home → Create Design panel → Set Pressure Network Catalog
    • T:\LCU-GENERAL\PIPES CATALOG\LCU-PressurePipes\Imperial_AWWA_PVC.sqlite
    • If you are editing a catalog from the Civil 3D installed location or if the catalog is in use by Civil 3D the catalog will be read only. It's best to close Civil 3D and make a copy using the SaveAs command in the Content Catalog Editor before making your edits. SaveAs will also copy the files in the corresponding DWG and IMG folders.
  • 2. revise Cut Length
  • 2-A. create path-based Pressure Network using Layout Tools (creates both network and at least one pipe run)
  • 2-B. create path-based Pressure Network from AutoCAD entity or C3D Object
    • Pipe Network → Pipe Network Creation Tools
    • Create a pressure network and pipe run from a linear object such as a line, arc, alignment, polyline, feature line or survey figure
    • Network name: StormMain
    • Network description: current date
    • Network parts list: Storm Sewer
    • Surface name:
    • Alignment name:
    • Structure label style:
    • Pipe label style:
  • 2-C. create part-based Pressure Network (old way)
  • 3. Add Pressure Pipe Runs
  • 4. Add Pipe Bends/Point of Intersection (PI)
  • 5. Add Branch Fittings
  • 6. Add Appurtenance
  • 7. Creates and edits a profile for a pipe run
  • 8. Edit Pressure Pipe Runs Vertically
    • The pipes can be vertically offset in profile at increments equal to the cut length of the pipe or simply in straight sections of pipe only offset at the fittings.
  • 9. Pipe Conflicts
    • define override station ranges
  • 4. Network Layout Tools
    • select surface
    • select junction structure
    • select pipe
    • toggle flow direction, arrow pointing down is used when starting upstream drawing the network
