Attaching a PDF

Ana writes the Length, Perimeter, and Area Teach Book in InDesign and exports it as a PDF. Lucía does the same for its Spanish version.

In the tools, the Teach Book is a resource: a few fields, such as its title, with a version for each language. The PDF is a file, uploaded and kept apart from the resource, and each language's version places its own.

Try it: select the Spanish version, then the file it places.
