Hi,

I've been working in a large project (20 members team). I want take full control of some elements in my Revit project, Like if I import cad in a floor plan(Pinned) one of my team member(unpin) deleted it. So now I want to give permission on Revit to them before deleting, finally Without my permission on Revit they couldn't be delete that cad. Is there any option in Revit ?

Please Help me Regarding this.
