I’d love something like Flash’s symbols — a way to update 100 instances of an object by editing the master object

I’d love something like Flash’s symbols in OmniGraffle — a way to update, say, 100 instances of an object by editing the master object. Being able to select objects based on properties is close, but only when changing stroke/fill/etc., not, for example, when adding lines to an object that you’ve already manually duplicated 100 times.

Anything like that coming soon? Or is it there under some name I haven’t thought of/couldn’t find?

Look up “Save as PDF” in the manual. Here’s an article with some more details: http://viget.com/inspire/how-to-make-master-objects-in-omnigraffle

It works pretty nicely, but it would be nice to have this functionality integrated a little more tightly with the program. I emailed support about this, it’s on their radar but no timeline.

That looks awesome! Thanks for posting this.
