The number of user accounts you can add to your Projetex 3D network is unlimited, but only a certain number of those accounts can be active at any given time.

Every concurrent workstation connection available to your license also gives you the right to have 3 more active user accounts.

So a license for one workstation can have up to 3 active users at a time, a license for two workstations can have up to 6 active users, and so on.

Please keep in mind that the default System Administrator account also counts against this limit.
