Split view

Split view shows two documents (or two parts of the same document) at once. Each pane has its own scrolling, zoom and current page, so you can compare drawings or read one page while editing another.

Open a split

Open a document. In the app: Help ▸ Show me
Click Split on the toolbar, then choose Split. With one document open it appears in both panes; with several open, the current document is paired with the one you used just before.

You can also use the View menu: Split vertically (side by side) or Split horizontally (top and bottom).

Choose what each pane shows

The Split button menu offers:

Item	What it does
Split	Starts a split (shown only while not split).
Split this document	Shows the current document in both panes.
Side by side with	Lists your other open documents; click one to pair it with the current document.
Choose documents…	Opens the Split view dialog: pick the document for Left / top pane and Right / bottom pane, and choose vertical or horizontal.
Split horizontally	Starts a top-and-bottom split (shown while not split).
Switch to horizontal / vertical	Changes the orientation of an open split.
Close split	Returns to a single pane.

Each pane also has a picker at its top for changing the document it shows. Choosing a tab in the tab strip while split puts that document in the focused pane.

Resize the panes

Drag the divider between the panes. Double-click it to return to 50 / 50.

Close the split

Choose View ▸ Unsplit, or Close split in the Split button menu. If you close a tab that one pane is showing, that pane switches to another open document; if none is left, the split closes.

Note

The focused pane is the active document. Tools, menus and the status bar act on it. The pane you last worked in is the focused one.

Tip

The Split button looks pressed while a split is open.
