Opening and Importing Documents

In addition to its own documents, OmniGraffle can open (or import) documents created in other similar applications. It can also open documents that aren't necessarily graphic in nature and create graphic representations of their data.

To open a document while running OmniGraffle, choose Open (⌘O) from the File menu. (There are several other ways of opening a document which are generic to all Mac OS X applications; see Mac Help for more information.)

OmniGraffle can open documents of the following types:

•	OmniOutliner (.ooutline) - Another Omni product; an application for easily organizing ideas into outlines and task lists. OmniGraffle imports outlines as hierarchical diagrams.
•	DOT (.dot) - Also known as GraphViz, an open-source graph visualization tool developed at AT&T Labs.
•	ProjectBuilder (.pbproj) - When importing a ProjectBuilder file, OmniGraffle uses the Objective-C headers to construct a diagram of the inheritance, protocol, and category relationships.
•	Frameworks (.framework) - As with importing a ProjectBuilder file, OmniGraffle uses the Objective-C headers from the framework to construct a diagram of the inheritance, protocol, and category relationships.
•	EOModeler (.eomodeld) - A tool for developers of WebObjects and Cocoa applications. When importing an EOModel file, OmniGraffle contsructs a diagram representing the database relationships it describes.
•	Diagram! 2 (.diagram2 and .dpalette2) - An application similar to OmniGraffle for NeXTSTEP and OPENSTEP. (OmniGraffle can import the graphics in a Diagram file, but not attached EPS images, sounds, or links.)
