For a fully-functional and superior navigational experience, use the HTML manuals. The HTML interface for Siemens Software and Mentor documentation is designed for effective navigation to help you quickly find what you need. Use the HTML manuals to search for topics, navigate between topics, and click links to examples, videos, reference material, and other related technical content. HTML manuals are superior to PDF manuals for web-based search and navigation.
You can also use a PDF Viewer, like Adobe Reader, to navigate to the install_location/docs/pdfdocs directory and view the PDF files directly. Note that you do not have documentation tree level search while using this method.
