Document Assembly
To edit page contents or perform page operations while viewing several
pages, activate Document Assembly view in the View menu or by
clicking the Document Assembly button at the bottom of your screen.
The Document Assembly toolbar lets you insert, extract, delete and
renumber pages; split your current document; or work with headers and
footers (create, update or remove them). This view shows small-sized
pages, not static thumbnails, so comments can be placed and text
selections copied to other pages, even in other documents.
The right-most button is Page Assembly.
It avoids the need to open
multiple instances of the program to insert pages from a set of
documents. Each document is displayed in a tab, using page thumbnails.
This lets you view documents and drag-and-drop the desired pages into
the target document. A wide variety of file types are supported,
conversion to PDF takes place when required.
