A virtual document represents project information for which no actual source file is available. For example, if you have a printed drawing but do not have the file from which it was generated, you can create a virtual document to associate it with the project.
A virtual document has a file data card but no physical content.
If you obtain access to the file the virtual document represents, you can replace the virtual document with it.

-
Without selecting a file, right-click in the file view area and select .
- In the New Virtual File dialog box:

- Click OK.
A virtual document with the icon 
and the extension .cvd is created. It is checked out to you.
