Selection export as PDF problem

Hi, I’m running OG 6.5.2 on El Capitan 10.11.3

Since OG 6, I’ve always had a problem when wanting to export (grouped) drawn shapes to PDF.
It always distorts the alignment of the shapes.
This is very annoying.
It has nothing to do with, because doing the same thing in Pages yields a perfect result in Preview.

So this is really a OG problem that’s been hanging around for a long time now and it’d be nice to see this finally fixed…

No one experiencing the same problem ?

Sorry for the trouble!

If you haven’t already, please email with an OmniGraffle file and the resulting PDF, so we can dig in to what’s happening. If it’s a known issue, we may be able to help quickly; if we haven’t seen it before, then we’ll have a good place to start addressing the issue.

Thank you!
