Does anyone know if more the one person can be working in
the same project but different drawing at the same time in P3D? If you have or
can, please let me know how to do this?
This is not a problem as long as the project has been setup in a network environment. A network setup will allow multiple users to access the project database.
can be done (might have to fight your IT dept though)
However the dbase you get as default install is pretty crappy...works ok if only one or two people are accessing it (but still randomly drops tags and line assignments, etc)...If you want multiple users to access the database then upgrade to one of the proper SQL suites
You sure can use multiple users in a project, on their own models/drawings.
As long as they can see the project and have the correct read+write capabilities to it, each user just XREF's the others users models if they have to refer to something.
