Open a plan set and move between sheets — MarkupCraft help

Open the set

Choose Open in the toolbar, or press ⌘OCtrl+O.
In the file picker, select every PDF of the set (hold ⌘ and click each file / hold Ctrl and click each file, or select a range with Shift), then confirm. Or drag the files from Finder / File Explorer / your file manager onto the sheet area. "Drop PDFs to open them" appears while you drag.
Wait while the status bar says "Opening <file>…". For big files it counts: "(10 of 60 sheets)".

Result: the Sheets list shows every page of every file, in the order you opened them, and the status bar says something like "Opened 3 files (42 sheets in the set)." If the files already had comments, it adds how many were read.

To add more files to the set later, open them the same way. They join the end of the list.

How sheets get their names

MarkupCraft names each sheet "<sheet number> — <title>", for example "A-101 — Floor plan", from the first of these it finds:

A name you typed with Rename sheet (below).
The PDF's own page labels, when the person who made the PDF set them (for example "A-101").
The title block: MarkupCraft reads the page's text and looks for something shaped like a sheet number (A-101, A1.01, M-201A, KA1-1), favoring the lower-right corner, the right-hand strip and the bottom band, and takes the largest wording near it as the title.
Otherwise, the file name and page: "Plans — page 3".

To see which one was used, press EscEsc until nothing is selected and Select is on, then look at Properties: "Read from" says "The page label", "The title block", "The file name" or "Typed by hand".

Move between sheets

Click a sheet in Sheets.
Press fn ↓Page Down for the next sheet and fn ↑Page Up for the previous one, or use the arrows in the bar under the sheet.
Type in Search sheets: part of a number ("A-2"), a word of the title ("roof"), or a file name. The list narrows as you type ("4 of 42"). Press ReturnEnter to open the first match. Clear the box to see every sheet again.

Each sheet keeps its own zoom and position until you close the set.

Zoom and pan

Mouse

Zoom: turn the wheel over the sheet. It zooms around the pointer. Or press ++ and −− (also with ⌘Ctrl), or use the zoom buttons. Type an exact percentage in the zoom box.
Fit: Fit page (⌘0Ctrl+0) shows the whole sheet; Fit width (⌘9Ctrl+9) fills the width.
Pan: drag with the middle button (the wheel), or drag with the right button, or hold SpaceSpace and drag, or choose Pan (HH) and drag. With nothing selected, the arrow keys move the sheet too.

Mac, Mouse

On a Mac trackpad, two-finger scrolling zooms (it does not scroll the sheet). To pan, hold SpaceSpace and drag with one finger, or switch to Pan with HH. A pinch zooms in Chrome, Edge and Firefox.

Touch

Zoom and pan: put two fingers on the sheet. Spread or pinch them to zoom around the point between them, and move them together to pan. Both happen at once.
Pan with one finger: choose Pan first. With any other tool, one finger draws or selects.
Fit page and Fit width are in the bar under the sheet.

You can zoom out well past the whole sheet and in up to 6400%. The sheet is redrawn sharp a moment after you stop moving.

Rename a sheet

When a sheet's name is wrong or missing:

Show the sheet.
Press EscEsc until nothing is selected and the Select tool is on. Properties now shows the sheet.
Choose Rename sheet.
Type the Sheet number and the Title, then choose Save.

Result: the sheets list, the bar under the sheet and the markups list all use the new name, and "Read from" says "Typed by hand". Renaming can be undone with ⌘ZCtrl+Z.

To go back to what the file says, open Rename sheet again, clear both boxes, and choose Save.

When you save, a typed sheet number becomes the page's label in the PDF, so other PDF viewers show "A-101" in their page box too. If you give any page of a file a number, every page of that file gets a label in the copy (its typed number, else its old label, else its page number). A typed title is kept for MarkupCraft but other viewers do not show it.
