I want to be able to do a mark-up that only one person in the team can see.
If an engineer does a mark-up for a technician, I don't want the Architect and the M&E to see it, why can't you have a drop down list of people that can access a private mark-up.
So if the engineer now does a mark-up for the technician, they would have to do it as a private markup, pdf it, save on to your own server as you can't save a pdf into BIM360, then drag and drop it back onto BIM360. As this is the only way, what's the point to using BIM360 for internal mark-ups?
