AutoCAD – Drawings

Sheet sets in AutoCAD: how to build one, and the three samples already installed

Sheet sets in AutoCAD gather a whole drawing package into one ordered list that plots in a single pass. AutoCAD 2027 already ships three complete samples.

A structural package runs to thirty sheets scattered across half a dozen folders. Plotting means opening each file, setting the paper size again, plotting, and hoping nothing was missed. Adding one drawing in the middle means renumbering thirty title blocks by hand.

Sheet sets in AutoCAD exist to remove both jobs. They gather the sheets into one ordered list, plot the lot in a single pass, and let the sheet numbers look after themselves. This article works through it step by step, with the three sample sets AutoCAD has already installed on your machine. For the full drawing-production workflow see our AutoCAD for Construction course.

What a sheet set is, and how it differs from a folder of drawings

A set is an ordered list pointing at layouts that live inside several different DWG files. It holds no linework of its own.

That whole list sits in one file with the extension .dst. This is the part most often misunderstood, so it is worth stating plainly: the dst file holds only the list and the paths, not the geometry. Copy it to another machine and leave the DWGs behind and it opens as an empty set of broken sheets.

That file is not readable text either. Opened in Notepad it is nothing but rubbish characters, and it is not XML however many people assume it is.

The real difference from a folder of drawings comes down to three things. A set keeps the sheet order, so sheet numbers mean something. A set plots in one command. And a set feeds sheet number and sheet title straight into the title block, so inserting a drawing changes no title block by hand.

The sheet set manager: where to start it

Read straight out of the acad.cuix interface file of the 2027 release.

Way inWhat to use
Full commandSHEETSET
AliasSSM
Ribbonno button at all
Classic menuTools → Palettes → Sheet Set Manager
ToolbarStandard Annotation → Sheet Set Manager

That ribbon row is why so many people never learn the tool exists. Nowhere on the ribbon is there a button for it. Anyone working from the ribbon alone has almost no way of stumbling across it.

Two commands go with it, read from the same file:

CommandMenu
NEWSHEETSETFile → New Sheet Set
OPENSHEETSETFile → Open Sheet Set
SHEETSETHIDETools → Palettes → Sheet Set Manager

Creating a sheet set, step by step

One thing has to be in place first, and skipping it wastes the effort: every sheet must be a properly named layout inside its DWG. A set points at layouts, not at files. Building layouts is covered in our article on layouts in AutoCAD.

StepWhat to doWatch for
1Type NEWSHEETSETOr File → New Sheet Set
2Choose Existing drawingsChoose An example sheet set to start from a sample
3Name the set, pick where the .dst goesKeep the .dst on the same drive, same branch as the DWGs
4Browse to the folder holding the drawingsThe program scans and lists every layout it finds
5Untick layouts that are not sheetsScratch layouts, plot tests
6Next then FinishThe palette appears with the sheet list

Step 3 decides whether the set survives. The .dst records a path to each DWG. Put it on one drive, leave the drawings on another, then rename a folder one day, and every link breaks at once.

Once the set exists, right-click the set name, choose New Subset, and drag sheets into groups so the list reads as a tree.

The three samples AutoCAD has already installed

This is the part almost no page mentions, and it is the fastest way to learn the tool. AutoCAD 2027 installs three complete sample sets with real drawings behind them:

Sample setThe .dstDrawings
ArchitecturalIRD Addition.dst, 148 KB11 sheets at the top level, plus 13 resource drawings in a Res folder
CivilCivil Sample Sheet Set.dst, 40 KB14 DWG files
Manufacturingmanufacturing sheet set.dst, 65 KB15 DWG files

They sit in C:\Program Files\Autodesk\AutoCAD 2027\Sample\Sheet Sets\.

The Architectural set holds 11 sheets in two subsets: a T-01 title sheet, an Architectural group of six running from AS-01 to A-05, and a Structural group of four from S-01 to S-04. Open any one of those files and a real, fully organised package is there in front of you, which reads faster than any tutorial.

Six variables that decide how a sheet set behaves

VariableDefaultWhat it decides
SSMAUTOOPEN1Opening a drawing that belongs to a set opens the palette
SSLOCATE1Opening a drawing finds and opens the set holding it
SSMPOLLTIME60Seconds between refreshes of sheet status
SSMSHEETSTATUS2When sheet status gets refreshed
PUBLISHALLSHEETS1Publish loads every sheet, not only the open one
BACKGROUNDPLOT0Whether plotting runs in the background

The first one is worth testing rather than believing. Close the palette with SHEETSETHIDE and open a blank drawing: the palette stays closed. Open A-01.dwg from the sample set and the palette opens by itself, 270 pixels wide, exactly as in the picture at the top of this article. Two opposite outcomes in the same run, so that is SSMAUTOOPEN at work rather than coincidence.

SSMPOLLTIME at 60 explains a common puzzle: a colleague has just edited a sheet and your palette still shows the old status. It only asks again once a minute.

A sheet list table on the cover sheet

A drawing index is the table of sheet numbers and titles that sits on the cover sheet. Built by hand, every added drawing means editing the whole table again.

Open the cover sheet, right-click the set name on the palette, and choose Insert Sheet List Table. The program builds a table that takes sheet numbers and titles straight from the list.

Two things to know first. Do not type over a cell in that table — typing over one breaks its link and it stops updating. To change the wording, change the sheet title on the palette and the table follows. And the table does not refresh itself: after adding a sheet, right-click the table and choose update.

The sheet number in the title block is a separate mechanism, and the more valuable one. The title block uses a field pointing at a sheet property, so reordering sheets changes the number in the title block without opening a single file. Inserting and editing title blocks is covered in our article on blocks in AutoCAD.

Publishing a sheet set

This is the real reason to build a set in the first place.

Right-click the set name and choose PublishPublish to Plotter, or Publish to DWF/PDF for a single multi-page PDF. The whole set comes out in one pass, in sheet order.

CommandRibbonMenu
PUBLISHOutput → Plot → BatchPlotFile → Publish
ETRANSMITnoneFile → eTransmit

PUBLISHALLSHEETS at 1 means the Publish dialog arrives preloaded with every sheet. BACKGROUNDPLOT at 0 means plotting blocks the session: on a thirty-sheet set you sit and wait, and setting it to 2 moves plotting into the background.

ETRANSMIT is the command to remember when sending a package out. It wraps the whole set with every referenced file, font and plot style into one archive, so the recipient is missing nothing. References are covered in our article on xrefs in AutoCAD.

What changed in the 2027 release

The What's New page for AutoCAD 2027 gives this tool exactly one sentence: "The Sheet Set Manager palette now allows for multiple sheets to be selected and then the editing of common properties."

From the 2027 release you can select several sheets at once and edit the properties they share. Previously that meant one sheet at a time. On a thirty-sheet set where the same field has to change — client name, issue date — that is a real saving.

Three things people say that are not true

What people sayWhat is actually the case
Copying the .dst moves the whole set to another machineThat file holds only the list and the paths, and no linework at all
Sheet sets have a ribbon buttonThere is none; type SHEETSET, type SSM, or use Tools → Palettes
You have to build a set from scratch to learn itAutoCAD installs three complete samples, and reading one is quicker

Frequently asked questions

What are sheet sets in AutoCAD for?

Gathering the sheets of a package that live in many DWG files into one ordered list, so the whole lot plots in a single pass and sheet numbers fill themselves into title blocks.

How big is a .dst file?

Very small, because it holds no geometry. The three samples on the 2027 release have .dst files of 148 KB, 65 KB and 40 KB, while their drawings run to 4.4 MB, 4.2 MB and 5.5 MB respectively.

Why does the palette open on its own?

Because SSMAUTOOPEN is 1 and SSLOCATE is 1. Set SSMAUTOOPEN to 0 and it stops.

A colleague edited a sheet and my palette has not changed?

Sheet status is only re-checked on the SSMPOLLTIME cycle, 60 seconds by default. Wait a minute or press refresh on the palette.

Is there a shorter alias than SHEETSET?

Yes, SSM. It is a stock alias in the acad.pgp of the 2027 release.
