Profile Pipe Crossings QC

Audits every alignment's profile views for pipes that cross the alignment but aren't drawn in the view (or aren't on the crossing style), and can auto-draw each missing crossing into its correct profile view: the missed utility that otherwise becomes a field conflict.

Audits every alignment's profile views for pipes that cross the alignment but aren't drawn in the view (or aren't on the crossing style), and can auto-draw each missing crossing into its correct profile view: the missed utility that otherwise becomes a field conflict.
Plan: transverse pipes cross the alignment → profile view: each crossing must be drawn (sliced ellipse). PLAN Alignment CL SS main (along → not a crossing) WTR STA 1+55 FM STA 4+10 offset flips + → − = crossing PROFILE VIEW EG WTR drawn FM MISSING 0+00 2+00 4+00 Auto-draw → AddToProfileView; run twice to set the crossing style. Compare vs PipeOverrides / GetPressurePipeOverrides → Missing / Wrong style.
Alignment / profile view   Crossing drawn (pass)   Missing crossing (ERROR)   Along-alignment main (screened out)   Ground profile

What it does

  • Snapshot: every pipe, gravity + pressure; curved pressure mains sampled along their true horizontal arc.
  • Crossing test: a pipe counts only when its offset flips sign and it runs transverse (across-ness test), screening out the longitudinal main.
  • Projections past the alignment ends are round-trip-validated so no phantom STA 0+00 crossings.
  • Compare: against PipeOverrides (gravity) / GetPressurePipeOverrides (pressure) per view.
  • Report: Missing (crosses, not drawn, ERROR) or Wrong style (drawn, not on crossing style, WARNING).
  • Auto-draw: each missing crossing drawn via AddToProfileView; whole run is one Undo.

Settings & options

  • Crossing style name: the profile display style for the sliced-pipe ellipse (default Crossing).
  • Auto-draw missing pipes: on by default; draws each crossing into its correct view.
  • Also set crossing style: off by default, leaving added pipes Not Overridden shows what the tool added. When on, run twice (Civil materializes the override only after the draw commits).
  • Include road profile views: on by default, centerline-alignment views audited too.
  • Across-ness ratio / min offset span in settings.json tune crossing vs main.
  • Output: <drawing> - Profile Pipes.csv + findings palette (double-click to zoom); VDC_PROFILEPIPES_SETTINGS env override.

When to use it

  • Before issuing profiles - making sure every crossing utility actually shows in the profile views.

How to run it

  1. Run VDCPROFXING; confirm the crossing style name ("Crossing") and whether to auto-draw the missing pipes.
  2. Click OK; the tool finds every transverse pipe that crosses each alignment within its profile-view station range and compares against what's drawn.
  3. Review the missing / wrong-style findings in the palette (double-click to zoom); with auto-draw on, the missing crossings are drawn into their views. Undo (U) reverses the whole run.

Options

  • Crossing display style name: the pipe style whose profile display draws the sliced-pipe ellipse (default "Crossing").
  • Auto-draw missing pipes: on by default - draws each missing crossing into its correct profile view (gravity + pressure).
  • Also set the crossing style: off by default - leaving added pipes 'Not Overridden' shows which crossings the tool added. When on, run twice (first draws, second styles).
  • Include road profile views: on by default - road (centerline-alignment) profile views are audited too.

Watch out for

  • A pipe is a 'crossing' only when it runs across the alignment (transverse), not the main running along it - tuned by the across-ness ratio in settings.json.
  • Setting the crossing style needs a second run: Civil only materializes a freshly-drawn pipe's override after the draw commits.
  • Auto-draw modifies the drawing (one Undo reverses it) - save first if you want a clean fallback.
