Enough is enough. All my designers are Vectorworks/MAC based. I need to get them electronic files to mark up and return. Most all designers are mac based in my world, and this is probably true in your world, too. Don't get me wrong, there is a real manufacturing reason I have avoided macs like the plague (like accuracy), but unfortunately the people who sign off on our shop drawings are all mac based. Is there no version of Design Review that is Mac compatible?? I can't very well compel every designer we deal with to install and support Parallels, etc..they just won't do it - so instead I have to publish to PDF and maintain a separate co-ordinated set of PDF's. This wreaks Vault havoc.
I'm doing my best to move us to a dwf based environment, but apparently the Apple licensing fees/open code restrictions are too steep for even Autodesk.
