Same Items, Same Place, Every Sheet (VDCSHEETSTAMP)

The same items, in the same place, on every sheet: the "paste the seal block on all 40 sheets" command.

Pick the items on the sheet where they already sit, a seal block, revision stamp, standard note, anything in paper space, then the dialog chooses which sheets get them: this drawing's layouts (checklist) and any other drawings added to the run, all of their sheets.
Every placed copy is tagged with the stamp's name, so a re-run finds its own work: Skip sheets that already carry it (default, re-running is a no-op), Replace the previous copies with fresh ones, or Add Anyway.
Anchor by absolute coordinates (identical title blocks) or by offset from each layout's lower-right corner (sets mixing sheet sizes).

Added drawings are written without opening them on screen; each gets a .vdcstamp.bak beside it first, a drawing someone has open is skipped and named, and a drawing where nothing changed is not re-saved.
The source sheet is excluded automatically, the originals never get a copy stacked on themselves.
Pure AutoCAD (both bundles). Settings in %APPDATA%\VDC\SheetStamp\. Ribbon: VDC Sheets → Sheet Sets → Sheet Stamp.

When to use it

Sealing a set - the PE/PLS seal block onto every sheet.
A revision stamp, 'NOT FOR CONSTRUCTION' banner, or preliminary watermark across a submittal.
A north arrow, bar scale, or standard note that belongs in the same corner of every sheet.
The same mark across SEVERAL drawings in a project, not just the open one.

Open the sheet that already has the items, and run VDCSHEETSTAMP.
Select the items in paper space (not inside a viewport) and press Enter.
Name the stamp - SEAL, NORTH ARROW - and check the sheets to receive it.
Optionally Add Drawings; every paper layout in each one gets stamped.
Check the plan line at the bottom, then Stamp Sheets. A summary lists every drawing.

Stamp name: the identity a later run matches on. Keep it consistent between runs; SEAL and NORTH ARROW are independent of each other.
Sheet already stamped: Skip (default - a re-run does nothing), Replace (erase the old copy and place a fresh one), or Add anyway (can stack duplicates).
Position on each sheet: same paper-space coordinates (default), or the same offset from each sheet's lower-right corner for sets that mix sheet sizes.
Back up added drawings: on by default - this drawing has UNDO, an added drawing does not.

Pick in PAPER SPACE, not inside a viewport - model geometry picked through a viewport is not on the layout and is ignored.
An added drawing that is open in AutoCAD is skipped and named in the summary, never half-written. Close it and re-run.
Change the stamp name and the tool no longer recognizes copies placed under the old name - they will not be skipped or replaced.
Absolute positioning on a set that mixes sheet sizes can put the mark off the smaller sheets; use the corner option there.
