Part 1 Getting the first set in

How a plan set arrives, from an empty tab to filed sheets. 3b is the tab with nothing in it and one action; 6a is the same tab for someone who cannot file. 8a asks what is being added, 3e names the set, 6b is the reading, and 6c is a file that could not be read. 9a and 9b are the same door for a link, and a link that would not open. The file is saved before anything else happens, and every primary names its own scope.

3b Plans, with nothing filed

This one is waiting on the homeowner, so it takes one action and is drawn as a hairline ghost of the filing cabinet that will replace it — no fill and no lift, because there is no object to raise. The support line says what the set is for rather than how to upload it, and the second sentence on the ground says what the plans unlock, which is the reason to bother.

Once a set is here you can open any sheet on site, and ask it where a room is. Nothing in your house record changes until you choose to add what a reading finds.
6a Empty, for someone who cannot file

3b hands the homeowner one action. A builder or a household member without that right sees the same tab with no button, because a button they cannot press is worse than a sentence. The sentence names who files the set, which is the only thing they can do with the information.

8a Add drawings, from the cabinet

The action on 1c opens a sheet rather than a screen: the reader is choosing what kind of thing they are adding and needs to come straight back to the cabinet. It routes, so it is a run of chevron rows with no primary and nothing pinned. Each row says what will be filed, not how the file gets picked.

9a Add a set from a link

Architects usually send a link, not a file. The field asks for what to paste, and the hint says what the link can be, not a format. The primary names what it will do. Nothing is filed by this step, and the screen says so.

Fetch the set
I read the link once to get the file. I do not sign in as you, and nothing is filed until you have named the set.
9b A link that would not open

Most often the link wants a sign-in. It says what is still true first, that nothing was filed, then what to do. Cause stays out of it: no status code, no address error. The way forward is the ghost button, hugging, because it is not the screen’s primary action.

3e Adding the plan set

A flow, so the dock is gone and the app bar carries the way out. The set is named by what it is for, and the revision is asked for because the argument on site is almost always about which revision somebody is holding. The reading is a separate act with its own screen, which is why the primary promises to file the set and nothing more.

File this plan set
Filing it puts the sheets in the cabinet. Reading them for rooms is a separate step, and nothing goes into your house record without you seeing the whole list first.
6b The set is being read

Between the file arriving and the sheets being filed. The file is already saved, so that comes first. Each stage is a thing the system owns, written as what it is doing, with no spinner, no percentage and no denominator. Nothing can be opened yet, and the frame says so rather than showing sheets that are not there.

You can leave this screen. I will tell you when the sheets are filed, and nothing in your house record changes until you choose what to add.
6c A file that could not be read

A scan, a photo of a page, or a password-protected file. The sentence says what is still true first, that the file is kept, and then what is not, that no sheets were filed. Cause never surfaces: no error code and no format lecture. The one way forward is a real button, and it hugs because it is not the screen’s primary action.

The file you sent stays in Papers & permits until you remove it, so it is not lost while you look for another.
Part 2 Reading the set into the house record

The two flows where a drawing becomes house record, from the review entry through rev 4 and the apply that failed. Seven clear matches stay quiet and never become seven confirmations. The review and the apply are different acts, so nothing is canonical until the whole list has been seen. Human work always stays.

5a Nine spaces, two questions

A finished read does not become nine interruptions: the seven clear matches are summarised and the review exists only for the two that matched more than one room type. No confidence figure anywhere, and starting the review writes nothing.

Review two spaces
You will see all nine before anything changes in your house record. Answering these two creates nothing on its own.
Not now
5b One question, and what it is not

The drawing's label is kept either way, so the screen says so in the sentence above the options: this choice is about which decisions belong in the room, not about its name. One of two is a bounded position because the count was known before the review started, and the two room types come from what the sheet actually supports rather than a taxonomy picker.

{{ roomCta }}
Nothing is chosen for you when this screen opens, and nothing is recorded until you have seen all nine.
Neither of these
5c The whole preview

Every proposed space appears before the write, not just the uncertain ones, and each row traces back to the sheet it came from — the two the reader settled say so instead. This is the first screen where anything can become canonical, so the action names the transaction and the count.

Add nine spaces
This creates the spaces and only the decisions that fit them. It does not change rev 3.
Back to the two choices
5d In the binder

A house-shaped result rather than a technical receipt: what is filed, and the two calls the reader made, kept visible because they are now provenance. It does not repeat all nine rows after the transaction has committed, and it offers the two places somebody actually goes next.

Open the house
Every space keeps rev 3 and its sheet behind it, so a later revision can be compared rather than guessed at.
Back to plans
5e Everyone else can see, not apply

A builder or invited collaborator reads the same result and gets neither the two prompts nor an apply control — the action is absent because the permission is, rather than sitting there disabled. The wait names the person who can move it, which is more use than a permission error.

Only Philip can choose the room types and put these spaces in the house record. Everything the read found is here to read in the meantime. Back to plans
5f What changed in rev 4

The comparison leads with room meaning rather than drawing geometry: most of the house still matches, and the three that moved are named as sentences. Protection comes before the choice — the garage is gone from rev 4 and already carries work, and the screen says it survives before it asks anything.

A later plan cannot erase something you or Nora changed. Whatever you choose next, every choice, answer, note and file stays where it is. Choose what happens
5g Update, remove or keep

One decision with three real meanings, each written as what it will do to rooms and decisions with nothing saved to them. Remove is not a quieter spelling of update, so it says its own consequence here and gets its own preview after. Nothing is preselected in the live screen.

{{ treatCta }}
Your choices, answers, notes and files stay with you in all three. Rev 4 cannot remove them.
5h Exact before irreversible

Two runs, named by what happens to them: what will change, and what will stay. The button repeats both the adoption and the treatment, because a generic confirm would hide the consequence, and the note says the preview stops being valid the moment somebody adds work while it is open.

Use rev 4 and keep your work
If anything changes while this is open, I will stop and show you the comparison again rather than remove something somebody just added.
Back to the three choices
5i Rev 4 is current, and the garage survived

Success names the exception as well as the change, because "everything updated" would be shorter and false. Rev 3 stays readable as the source that came before, so the provenance behind every earlier space is still there.

Open the house
Rev 3 is still in Plans & drawings as the source that came before this one.
Back to plans
5j Nothing changed

A failed transaction can promise the house record is untouched because a partial apply is not permitted — rooms, sheet links and decisions commit together or not at all. The treatment and the two review choices are still here, so retrying is not repeated work, and no cause surfaces: there is no status code to read.

Part 3 The cabinet, and adding to it

The filed set and everything that changes it. 1c is the cabinet with its add action, 6f the revisions, 8b one sheet, 8c a sheet number that is already filed, 8d a photograph, which is kept and not filed, 9e what was removed and can come back, 9f offline, 9g read-only.

1c Plans, filed the way they were drawn

A-1 leads, because it is the sheet anyone opens first, and the set’s provenance sits under it in the same card. Below it a filing cabinet, grouped by the discipline the set states rather than one inferred from a sheet number, with the one field an architect would want kept on the row: the scale. What the tab cannot do is a sentence on the ground in the homeowner's own words, not a badge about a missing column — a callout heading and the paragraph it names, which is a tighter gap than a state's two sentences.

Add drawings
A-1 preview
Sheets are filed by number, not by room. To find the kitchen you open A-1 and look for it, the same as you would with the paper set on the table.
6f Every revision, newest first

What replaced what, in one run. The current revision is green because that is already true; the one waiting is the only thing with a blue action; superseded sets are kept to read and say so. Dates and the person who issued each, the same evidence line on every row.

Older revisions are never deleted. Anything you saved from one still points at it.
8b Add one sheet

For a sheet that arrived on its own: a detail an architect sent after the set, or a page that was missing. A flow, so no dock and the bar carries the way out. Discipline is asked as the set states it, and the primary names the sheet it will file, not "Save".

File sheet A-5
8c A number that is already filed

The one place adding a sheet can lose something, so it stops and states both sides before it acts. Replacing keeps the old sheet to read, which is stated before the choice and not offered as a third option. Selection sits on the surface, so it is a run of answers in a card with the marker carrying the choice.

Replace A-3 and keep the old one
8d A photograph of a page

A photograph is evidence that a page existed, not a sheet: it has no number, no scale and no revision, so it cannot stand in the cabinet. The screen says that before the reader files it, and says where it goes instead. The optional field is the ask, not the format.

Photograph preview
Keep this photograph
If you want the whole page readable and searchable, ask your architect for the PDF and add it as a sheet.
9e Removed in the last 30 days

A removed sheet is not gone yet, so the cabinet says where it is and how long it has. Each row states the days left in words. Putting one back is a real button on the row’s foot, reversible, so it is tonal. The section only exists while something is in it.

After the days are up a sheet cannot be put back. Your original file is kept either way.
9f The cabinet, offline

Say what still works first. The sheets already opened are readable, and adding waits, so the button is absent rather than disabled. The sentence names what waits and when it resumes.

Sheets you have not opened need a connection.
9g The cabinet, read-only

What a builder or a household member sees. Reading and inspecting never depend on being allowed to change, so every sheet opens. The add action is gone and the sentence names the person who files, the inert pattern from the system.

Pat is the only person who can add, replace or remove a sheet in this cabinet. You can open, share and download any of them.
Part 4 A sheet, and what you can do with it

The viewer and its actions: 4a a sheet on site, 8e its actions, 8f removing it, 9c sharing it, 9d replacing it. Then the conversation that cites it, 4b to 4g. The thread is a room inside Plans & drawings, so every frame drops the dock and names the revision before the first turn.

4a A sheet, on a phone, on site

A drawing at a quarter inch to the foot needs every pixel, so the sheet takes the full width and the chrome is one strip under it carrying the two things an argument on site turns on: which revision this is and who sent it. Three of nine is a position in the set you opened, not a progress figure, and the two actions are taking the sheet with you before the signal goes, and the rest of what can be done with it, which opens 8e.

More actions
8e A sheet’s actions

From the sheet on 4a. Another routing sheet, so a chevron run with nothing pinned. The one destructive row is last and says what it does in its own caption; it leads to a confirmation rather than acting here. A member without the right sees the first two rows only, because reading never depends on being allowed to change.

A-3 preview
8f Removing a sheet

Exact before irreversible: what goes, what stays and for how long, in that order, then one outline button that names the sheet. It is an outline because a destructive action never takes the filled weight. Anything the reader saved from the sheet, and any answer that cites it, is named so nothing is discovered afterwards.

Remove A-3 ElevationsKeep it
Answers in the thread that cite A-3 will say the sheet was removed instead of linking to it.
9c Sharing a sheet

From 8e. A link to one sheet at one revision, read-only, and it says so before anyone copies it. The person opening it needs no account. It names the revision because a link that follows the newest one would change under the reader.

A-3 preview
Copy the link
You can turn the link off from this sheet at any time.
9d Replacing a sheet

From 8e. It shows the sheet being replaced, so nobody replaces the wrong one, and the primary states that the old sheet is kept. The revision is asked for again, since a replacement almost always is one.

Replace A-3 and keep rev 3 to read
4b Asking the set, source first

The opened revision is the first object on the screen and every later turn inherits that boundary, which is why this thread is not behind the global Ask door. The two example questions are the shape of what it can answer, and the line above the composer says what the conversation cannot change.

Questions read the plans. They do not change your plans, your rooms or anything in your house record.
4c The reply being assembled

The question stays in the transcript while the work happens, and the pending reply is drawn as a reply rather than as a loader. The four stages are the ones the system actually owns, on a spine where done is green and the current one is the pigment node, and the line under them says the reader can leave.

4d A cited answer

The answer is short and the emphasis is one phrase inside the sentence, never a second line. Its source is not a footnote: it follows the claim in reading order as a row that opens the exact sheet, and what the answer does not cover is product copy, visible before anybody carries it onto a job site.

A follow-up stays on rev 3 unless you deliberately open another set.
4e The citation, opened

The same viewer as 4a with one temporary region on the sheet and one strip saying what it supports — it is evidence for an answer, not the start of an annotation tool, and leaving the question clears it. The drawing still gets nearly all the pixels.

4f Nothing in this set says

Not found is a normal reply, and it is only allowed once every relevant sheet finished reading. It names the revision rather than the house: the plans do not specify a finish, which is a different claim from the house not having one, and the conversation stays open.

Ask a follow-up about rev 3
4g A sheet in the way

Incomplete is not not-found, which is the whole rule this state exists to enforce: one sheet that stopped reading could hold the answer, so the product refuses to call it missing. The recovery is the sheet's, not the question's — retrying reads A-2 again and does not spend another question, so asking again stays a deliberate act.

Read A-2 again
This reads the sheet, and only the sheet. Your question stays as it is until you ask it again.
Ask something else about rev 3
Part 5 By room

Sheets are filed by number, so a room asks the set. 6d is the answer, 6e a room the set does not draw.

6d Sheets that show one room

The way in from a space. Sheets are filed by number, so a room asks the set which sheets draw it. The answer is a short list with the reason each sheet is here, and it ends by saying what the list cannot tell you. Each row opens the sheet, as in 4a.

Read from the sheet titles and room names in rev 3, on 14 May. A sheet that draws the kitchen without naming it will not be on this list.
6e A room the set does not draw

The empty for one room rather than the whole tab. The set is filed, so the tab is not empty, and this is not an error either. It is a plain answer with the revision it came from, and the rev 4 route is stated because that is where the pantry lives. No button, since nothing the reader can press adds a room to a drawing.

Part 6 On the desk

The cabinet and the rev 4 decision at desk width, with the same add action. 10a the sheet viewer with its panel, 10b the answer beside its source, 10c adding a set as a side sheet.

7b The filing cabinet, wider

A-1 leads, because it is the sheet anyone opens first and the only visual thing on a screen that is otherwise nine names, and the set's provenance sits beside it in the same object rather than in a band of its own. The discipline groups are the same runs at a wider measure, two columns deep. What the tab cannot do stays a sentence on the ground at the foot of the second column, where it reads as the page's own voice rather than as a notice.

Sheets are filed by number, not by room. To find the kitchen you open A-1 and look for it, the same as you would with the paper set on the table.
7d The rev 4 decision, one level down

A bounded decision, so the rail stays for orientation but the way back is an up-link above the head rather than a rail item — the rail goes to places. The zone does not survive the translation: the three treatments become a named run of option blocks on the ground, held to a reading measure instead of stretched across the canvas, with what is protected beside them rather than under a fold.

10a A sheet on the desk

The drawing takes the width and the height, and what was a strip under it becomes a fixed panel beside it. The actions that were behind “More actions” on 4a are in view here, because there is room to show them and nothing to hide. Reading still comes first: revision and sender lead the panel, then what can be done. Removing is last and leads to 8f, which arrives as a side sheet.

10b The answer and its source, side by side

Where 4d and 4e take turns, the desk shows both: the conversation stays on the left with the answer, and the sheet it cites sits on the right with the one region marked. Nobody leaves the thread to check a source. Choosing another source row changes the sheet and leaves the conversation where it is. The marked region is evidence for an answer, so it clears when the question does.

10c Adding a set, over the cabinet

A flow at desk width is the same sheet as on the phone, coming from the right at 480px. The cabinet behind it is held to the strip that is actually visible, so it reads complete at that width and nothing important sits under the scrim. The title, the order and the primary are exactly those of 3e, and the primary is pinned, since it is one answer.
