The OmniGraffle Pro Upgrade enables even more helpful features.
It’s a one-time purchase that you can make via the App Store.
You can buy an upgrade to a Pro license at the Omni Store.
Microsoft® Visio® Import/Export
Collaborate with Microsoft Windows® users. OmniGraffle Pro imports the following Visio file types: Drawing files (.vsd, .vdx, and .vsdx), Templates (.vst, .vtx, and .vstx), and Stencils (.vss, .vsx, and .vssx).
OmniGraffle Pro exports your drawings in .vdx format, which can be opened by Visio 2013 and earlier.
Shape Combinations
Combine two or more objects on the Canvas to create custom shapes. Don’t like the combination you’ve made? That’s okay; you can also uncombine objects to restore them to their former selves.
Shared Layers
Share layers with multiple canvases in the same OmniGraffle document.
Tables
Merge two or more objects to create a table, and then resize the table to add additional rows or columns to suit your needs.
Custom Data
Assign names, add descriptive details and notes, and add custom key-value data to every single object on the canvas—or to the canvas itself.
