Rev Table

Inventories every revision cloud and delta triangle across model space and every layout, pairs each cloud with its delta tag, and flags the clouds nobody wants to miss at resubmittal: orphans with no delta and stale clouds left over from a prior round.

Inventories every revision cloud and delta triangle across model space and every layout, pairs each cloud with its delta tag, and flags the clouds nobody wants to miss at resubmittal: orphans with no delta and stale clouds left over from a prior round.
Pair each cloud with its delta; current rev = highest numeric delta found (here = 2). 2 PAIRED, rev 2 ? ORPHAN, no delta in reach (WARNING) 1 STALE, tagged 1, current is 2 (WARNING) pairing reach (default 2 u) TITLE-BLOCK REVISION HISTORY (stray deltas = INFO, by design) 1 AGENCY COMMENTS, 2026-05-12 2 RESUBMITTAL, 2026-07-13 Number read from REV / NO / NUM attribute; description & date ride along into the CSV row.
Paired cloud (has delta)   Orphaned cloud   Stale cloud   Stray delta (INFO)   Title block

What it does

  • Recognizes clouds: closed polylines that are nearly all arcs (≥8 vertices, ≥80% arc, the REVCLOUD signature) on any layer, plus anything on the cloud layer wildcard (default *REV*).
  • Recognizes deltas: block inserts matching the name wildcards; rev number read from the first matching attribute (REV/NO/NUM…) with a numeric fallback.
  • Pairs a delta to a cloud when it falls in the cloud's bounding box expanded by the pairing reach (default 2 units, per space).
  • Flags orphans (no delta in reach, WARNING) and stale clouds (tagged older than the current rev, WARNING); stray deltas are INFO.
  • Scans model space and every layout; read-only except the optional table.

Settings & outputs

  • Current revision: 0 auto-detects the highest numeric delta; set explicitly mid-revision. Letter revs (A, B) never flag stale.
  • Dialog keys: cloud layer pattern, delta block patterns, pairing reach, current rev, table toggle; attribute tag lists in settings.json at %APPDATA%\VDC\RevTable\.
  • CSV per run, findings plus one INFO summary row per space (cloud/delta counts, rev numbers present, descriptions).
  • Findings palette zooms to each cloud/delta; paper-space hits note their layout in Location.
  • Optional table: one row per sheet/space (clouds, deltas, rev numbers, descriptions) at a picked point, drawing's current table style, current space.
  • Blind spot: clouds drawn as splines or exploded linework are invisible, use REVCLOUD or the rev layer.

When to use it

  • Before every resubmittal - stale clouds from the last round are the classic reviewer catch.
  • Building the per-sheet revision summary without walking every layout tab.

How to run it

  1. Run VDCREVTABLE; confirm the cloud layer pattern, delta block patterns, pairing reach, and the current revision (0 = auto: highest delta found); click OK.
  2. The tool scans model space + every layout, pairs clouds with deltas, and reports orphans / stale clouds to the palette and CSV.
  3. With the table option on, pick a point - one row per sheet: clouds, deltas, rev numbers, descriptions.

Options

  • Cloud layer (wildcards): catches clouds drawn without REVCLOUD; the all-arcs signature is recognized on any layer regardless.
  • Delta block names: comma-separated wildcards (default *REV*, *DELTA*, *TRI*); number/desc/date attribute tags configurable in settings.json.
  • Pairing reach: how far outside the cloud's box a delta still counts as its tag (in that space's units).
  • Current revision: 0 auto-detects the highest numeric delta; set it explicitly when the set is mid-revision.

Watch out for

  • Letter revisions (A, B) never flag stale - only numeric deltas participate in the current-rev comparison.
  • A stray delta with no cloud is only INFO - the title-block revision history triangles land there by design.
  • Clouds drawn as splines or exploded linework are invisible to the scan - use REVCLOUD or keep clouds on the rev layer.
