Draws real gravity pipes from destination-coded as-built shots ("SSMH INV TO MH 3"): the last step of the field-to-finish chain: VDCBUILDSTRUCTS creates the structures, VDCSETINVERTS loads them, this connects them.
"INV TO MH 3" → FROM = nearest structure, TO = the named one (drawing-wide) → pipe at the shot inverts. SSMH-7 (source) × "INV TO MH 3" @ 95.20 SSMH-3 ← matched from "MH 3" × "INV TO MH 7" @ 94.15 (reciprocal) one pipe, invert 95.20 → 94.15 (both from the field) no reciprocal shot? far end falls at the fallback slope (0.4%) name matching: normalize (case/space/dash) → exact wins → else UNIQUE ends-with ("MH 3" finds "SSMH-3") ambiguous (SSMH-3 vs SDMH-3)? skipped WITH the candidate list · already-connected pairs never doubled window loop + preview grid + CSV · pipe ends at invert + rise/2, connected both ends · then VDCPIPEQC
Coded shots   Structures + created pipe   Skips & cautions

What it does

  • Parsing: an invert code (INV/IE/PI/SEI/SEO/DRI, editable) + the keyword (default TO) + a name, all word-boundary matched against the RAW description.
  • Reciprocal pairing: two shots naming each other fold into ONE pipe with both field inverts; the second shot lands in the skipped list saying so.
  • Conservative: unmatched names, ambiguity, self-references, and already-connected pairs all skip with reasons, nothing is guessed.

Settings & options

  • Match radius (10' default) pairs the shot with its source structure; destinations are matched drawing-wide, the far manhole is usually outside the picked window.
  • One pipe family/size per run (drop-downs); the pipe joins the source structure's network; sizes aren't parsed from descriptions in this version.
  • Settings: %APPDATA%\VDC\AsBuilt\buildpipes.json (VDC_BUILDPIPES_SETTINGS). CSV: <drawing> - Build Pipes.csv.

When to use it

  • The as-built chain's last step: VDCBUILDSTRUCTS created the structures, VDCSETINVERTS loaded them, and the pipes are still missing.
  • The survey crew coded destinations in the field and drawing each pipe by hand is the alternative.
  • Record-drawing conversions where the pipe connectivity lives only in the point file.

How to run it

  1. Run VDCBUILDPIPES - check the invert codes, the TO keyword, the match radius, the fallback slope, and the pipe family/size. OK - Pick Windows.
  2. Window the surveyed area (shots inside; destinations are found drawing-wide).
  3. Review the preview: from / to / network / length / both inverts and whether the far invert came from a reciprocal shot or the slope fallback. Untick any row; Apply Checked.
  4. Keep windowing; Esc finishes. Then run VDCPIPEQC on the result.

Options

  • Destination matching: names normalize (case/spaces/dashes ignored); exact match wins, else a UNIQUE suffix match - ambiguity is skipped WITH the candidate list rather than guessed.
  • Reciprocal pairing: two shots that name each other make one pipe with both field inverts - the second shot lands in the skipped list saying so.
  • Fallback slope: used for the far invert when no reciprocal shot exists (default 0.4%).
  • Duplicate guard: a pipe already connecting the pair is never doubled - re-runs are safe.

Watch out for

  • Name discipline is everything: "TO MH 3" only works when exactly one structure name ends in MH-3 - rename structures (or fix descriptions) before fighting the ambiguity skips.
  • The pipe joins the SOURCE structure's network - crossing-network runs need a hand check.
  • Sizes/materials aren't parsed from the description in this version - one pipe family/size per run; resize afterward.
  • Gravity networks only.
