I am a beginner here also so may not fully answer but will try as I have set up my owner server for myself and and Engineer.
I set up a computer as my BIMCLoud Server
I share the project
Then I give myself and the Engineer rights to that project.
Then we both work.
I reserve the items I am working on and he does the same.
We can only work on those items and he is can only see my items
The screen updates as we work together
Really that simple
There was a BIM for Manager class the other day that helps with this and gives a good visual of options to help the process.
