Put a textbook page or topic file on the board

The textbooks and files attached to your curriculum can be put straight on the glass as a card, at any size, anywhere on the canvas — and you can write over them with the pen exactly as you would annotate paper.

How do I place a file?

1. Tap Topics on the left rail. Under each topic, its attached files appear as small chips.
2. Tap a chip. The file lands on the canvas as a card and the board confirms Placed with the file name.
3. For textbooks, tap Book on the rail instead. The panel is headed Book / PDFs with the subtitle For this class. Tap a tile in the grid.
4. Drag the card by its header bar — the grip icon is the handle. Resize it from the glyph in its bottom-right corner.
5. Write over it with Pen or Mark.

Rules and gotchas

• The file type decides the card. Images render as images, PDFs open in a viewer you can page through, 3D models open in a viewer you can spin, and anything else opens as a web card.
• Cards are placed at the centre of the screen with a small offset each time, and the header is always kept reachable — it cannot end up under the top bar or off the edge.
• Only files actually attached to the curriculum appear here. With none attached, Book reads No PDFs linked for this class. Attaching them is done in the admin panel.
• There is no way to open a file from the panel itself. Circin Canvas has no file picker and no import — everything on the board comes from the curriculum or from the resource library.
• A card that fails to load shows Couldn't load with a Retry button.

Close a card from the ✕ in its header. If several are open at once, the switcher is easier — see Arrange what is open on the board.
