How does VR co-exist with usual text documents such as Word documents?
First, if you want, say, to create a report, you can just insert VR diagrams into a Word text either by copying them, or, better, by using special operations that VR provides. Second, in a VR project you can include references to any documents, including Word. Then just clicking on the corresponding reference you open the document (a local one or on the Internet) in the corresponding application.
