Save Omnigraffle 5.1 files to be compatible with 4.x?
 

Hi,
I'm looking for how to save my 5.1 Omnigraffle files to be most compatible with 4.x. Maybe I missed it, but I didn't see any obvious answers under Export, Save As, or Google search.

Thanks!

The support ninjas may have more info, but if I remember correctly, the file format is designed to be forward-compatible. That means that the document should open in version 4; it'll render the document to the best of it's ability, but the v5-only content in the document will be ignored.

Yes, the file format is forward-compatible. Not just the file format, but more important, the object definition for each object. OM 5.x docs open in 4.x with no problem at all. Which really means, you open a 5.x doc, but you can only perform 4.x functions on the objects. You can even open 5.x stencils in 4.x.

I have not yet found "5.x-only content", I am not saying it doesn't exist, just that it is rare, and when you find such, you can fix it. AFAIK, there is either 4.x-functions or 5.x-functions on objects which are not version-specific, within limits and reaching the limits is rare.

The only "5.x only content" I have seen was very badly written (in 5.x) templates; once I rewrote the objects in simpler form, and re-saved the doc as a simpler 5.x template, it loaded perfectly into 4.x. Complex 5.x objects in templates cannot be rendered in 4.x. What I am saying is, if you have a need to frequently open 5.x docs in 4.x, keep them clean and simple, and keep the 4.x limitations (not really limitations) in mind.
