The Tekla Structures Multi-user Server 2.5.0 is a companion service that allows multiple users to collaborate on the same 3D building information model (BIM) simultaneously over a local area network (LAN). Unlike the newer cloud-based Tekla Model Sharing, this version is designed for on-premises setups where real-time, low-latency communication is critical. Download Instructions
Official downloads for Tekla software are hosted on Trimble Downloads.
Find the Version: To locate the 2.5.0 installer, select Tekla Structures 2020 from the version dropdown, then click All downloads. It is under the "Multi-user server" section.
Compatibility: Version 2.5.0 is forward and backward compatible, meaning it works with older and newer Tekla Structures versions (like 2024 or 2025) even though it isn't listed under their specific download pages. Setup Guide for Administrators
The multi-user server runs as a background service (xs_server.exe) that coordinates write access to the master model. Installation:
Install the package on a central server or a reliable workstation that stays powered on.
The default path is typically C:\Program Files (x86)\Tekla Structures Multi-user Server. Network Configuration:
Fixed IP Address: The server computer should have a fixed (static) IP address so clients can always find it.
TCP Port: By default, it uses TCP port 1238. Ensure this port is open in your Windows Firewall and any antivirus software. With the server running, your team needs to connect
Firewall Rule: Add xs_server.exe to the exception list to prevent connection blocks. Converting Models: Open a single-user model in Tekla Structures. Go to File > Sharing > Convert to a multi-user model. Enter the server’s name or IP address when prompted. System Requirements
The multi-user server itself is lightweight and has low CPU usage, often allowing it to run on the same machine as the Tekla License Server.
Operating System: Officially supported on Windows 10 and Windows Server 2019.
Networking: Minimum 100 Mbit/s; 1 Gbit/s is recommended for large models.
Stability: Requires identical subnet masks and unique IP addresses for all connected computers. Best Practices
Backups: Always set up scheduled backups for model data and store them on a different physical computer.
Consistency: All users working on the same model must use the same Tekla Structures version, service pack, and environment to avoid data corruption.
Performance: Large reference models can slow down saving; delete any that are no longer needed to keep the model responsive.
