I know this thread is a bit on the old side, but, has anyone been using GrabCAD lately?
I use it for a job I'm doing and I'm seriously thinking of porting a lot of content I do over to it, and using it for any projects with collaboratiors across multiple geographies, platforms, disciplines, and CAD packages as it's fairly platform agnostic.
It's free now, it wasn't before, and essentially works like Vault on Inventor does from back when I had to use that; but what I like is that it's super easy to take a file and share permissions with someone and they can view it in 3D from a browser or they can work on the files directly on their own CAD and then I see their uploaded versions later on. Beats the pants off Dropbox and other clouds for that purpose.
Main downfalls I've heard cited when explaining the system is a concern that someone else is holding your data, though I've yet to see any informed claim that the data is not held in the same privacy and personal ownership protections as any other cloud-storage solution; and the other that I've come across is that collaborators do need to sign up and keep up with yet another profile on yet another program, and if one is running a library system they have to make sure everything is migrated to and managed exclusively through folders that are sync'd to GrabCAD.
The other cool thing is that if you have non-proprietary reference data you wish to share, it can of course be publicly published to GrabCAD as many are aware. But it's the behind-the-scenes sharing and project management function of the GrabCAD Workbench that is relatively new to me and super awesome.
