Though expensive, OmniGraffle is an extremely effective and unique diagramming tool.


It is possible, and even fun, to create extremely high quality diagrams with OmniGraffle. The key is to begin in freehand drawing mode, and then progressively refine the drawing. This is best done using multiple layers.

Finished diagrams may be printed (with AirPrint), exported as PDF or PNG or native editable format (compatible with OmniGraffle for Mac), or sent to an iDisk or any WebDAV server.


Stencils are predefined shapes, often defined with meaningful connecting points. They can be as simple as a circle, or as complex as vendor-specific rack equipment. Stencils exist for planning office space and iPhone app design.

Graffletopia is a fantastic source for hundreds of OmniGraffle stencils.
