Multi-user system

A Tekla Structures multi-user system runs on a TCP/IP network and consists of:

  • A server computer running the multi-user server

  • A file server computer containing the master model

  • Client computers running Tekla Structures

Tekla Structures multi-user server as a service

Tekla Structures multi-user server runs as a service that is started automatically when you start the computer. You do not need to log in to the service.

Tekla Structures multi-user server performs the following main tasks:

  • Locks the model when somebody saves or numbers the model

  • Identifies client computers

  • Keeps track of active multi-users

  • Gives numbers for general arrangement drawings and multidrawings

  • Displays warnings if an another user has already edited or is currently editing drawings or the same model object

To optimize the performance of a multi-user system, run as few other programs as possible on the Tekla Structures multi-user server.

Server shutdown

Users should save their working models to the master model before the Tekla Structures multi-user server is stopped. If the service is stopped before saving the working models, for example because the server computer needs a restart, simply restart the service and have users save their working models to the master model.

Install Tekla Structures multi-user server as a service

The Tekla Structures multi-user server installer installs the multi-user server as a service. When you have installed the server, the service is always available and it is automatically started when the server computer is started. There is no need to log in and no need to start the server manually every time you start your computer. Tekla Structures multi-user server allows many users to work on the same model simultaneously.

We recommend that you use the latest multi-user server version available regardless of the Tekla Structures version that you use.

  1. Download the multi-user server software installation file from Tekla Downloads.
  2. Double-click the installation file to run the installation.
  3. Follow the steps in the installation wizard to complete the installation.

    The server is by default installed to:

    c:\Program Files (x86)\Tekla Structures Multiuser Server

    You cannot change the installation path during the installation.

    The multi-user server uses TCP/IP port 1238.

The installation log is written to the xs_server.log file that is available in c:\ProgramData\TeklaStructuresServer.

Change the server of a multi-user model

You can change the Tekla Structures server of a multi-user model.

  1. On the File menu, click Sharing > Change server.
  2. Enter the new server name or select it from the list.
  3. Click OK.

    If the connection to the new server cannot be established, the old connection is restored.


The file .This_is_multiuser_model located in the model folder defines whether the model is a multi-user or a single-user model. The file includes also the name of the server. You can open the file using any standard text editor.
