Worker

Headless job runner for unattended sessions: a dispatcher writes a small job JSON (drawing, output folder, operations), a worker Civil 3D or AutoCAD session runs VDCWORKERRUN , and a result JSON comes back with a status, an exit code, messages and outputs. Public, versioned contract: VDC.Worker/JOB-SCHEMA.md . No ribbon button - scripts and dispatchers drive it.

Command VDCWORKERRUN VDCWORKERTEST
Headless job runner for unattended sessions: a dispatcher writes a small job JSON (drawing, output folder, operations), a worker Civil 3D or AutoCAD session runs VDCWORKERRUN, and a result JSON comes back with a status, an exit code, messages and outputs. Public, versioned contract: VDC.Worker/JOB-SCHEMA.md. No ribbon button - scripts and dispatchers drive it.

Operations

  • drawing.probe: units and counts; with Civil 3D, surfaces, alignments, sites, parcels, pipe networks.
  • drawing.layouts: every layout's plot device, paper, plot style table and scale, optionally compared with allowed configurations you supply.
  • stormwater.pull: drainage areas (VDCDRAINAGEAREA's, closed polylines on layers, or traced to outlets) with areas and labels, built-upon area by category, lots per drainage area, pond stage-storage-discharge.
  • tables.push / stormwater.push: keyed tables written into a COPY of the drawing, saved beside the result; the same key updates in place.

Running it & safety

  • Set VDC_WORKER_JOB and run VDCWORKERRUN, pass the path as its one argument, or call (vdc-worker-run "C:/jobs/job.json"). VDCWORKERTEST runs a job by hand.
  • Never writes the source: hashed, copied into the output folder's _work area, only the copy opened, re-hashed at the end (exit 7 if it changed). Writes need "allowWrite": true and land as NEW files, logged in vdc-worker-audit.jsonl.
  • Exit codes: 0 ok, 1 warnings, 2 invalid job, 3 source problem, 4 an operation failed, 5 crashed, 6 output not writable, 7 source changed, 8 needs Civil 3D, 9 not licensed (LISP entry).
  • Draft work product: the result file and every pushed table carry the standard notice.

Dialog

VDCWORKERTEST dialog
VDCWORKERTEST - VDCWORKERTEST
VDCWORKERRUN - Headless: reads the job file named by VDC_WORKER_JOB or its one argument, writes a result JSON. No dialog by design.
