Considered a classic diagramming application by many Mac users, OmniGraffle helps you visually represent ideas, tasks, activities, and other things. The new 6.0.5 version introduces a revamped interface that addresses the dated look of its predecessor while improving on functionality and intuitiveness.
Great new interface: The OmniGraffle UI now sports dynamic sidebars that appear when needed and disappear when not in use. An approach similar to Microsoft's tidying of the Office ribbon might have been preferable, but Omni Group's revamping of the OmniGraffle interface is good.
Free syncing with OmniPresence: Your projects can be quickly shared with your other Mac or iOS devices through a background synchronization process. You can check what's being synchronized as well as pause the process at any time.
Presentation mode: This mode eases the presentation of diagrams by going full-screen and making canvases behave like slides. These canvas slides can be moved like a PowerPoint presentation, using either mouse clicks or arrow keys.
Multiple formats for exporting and Visio support: OmniGraffle can export diagrams or other creations in a number of formats, including BMP, TIFF, PDF, JPG, EPS, SVG, Visio XML, PICT Vector, PNG, and PSD. It can also conveniently import Visio XML files.
Designed for single-screen use: The older version of OmniGraffle let you use two screens; the new version does not. Some users will have to change the way they use the app, but for most users, the single-screen limitation will not be a major issue.
No CAD integration: OmniGraffle lacks support for AutoDesk file formats and cannot integrate CAD.
Feature-rich and relatively advanced, OmniGraffle may intimidate some users, even those who have tried its earlier versions. Some adjustment to the new interface will be needed, but this application is not that difficult to figure out. It offers a great range of features and outputs beautiful diagrams, wireframes, and sketches.
