Unlocking Real-Time Collaboration: A Deep Dive into Tekla Structures Multi-User Server 2.3.20

In the world of high-stakes structural detailing and BIM, speed and coordination are everything. While many teams are moving toward cloud-based solutions, the Tekla Structures Multi-User Server 2.3.20 remains a cornerstone for firms operating on robust local networks.

This post explores how to maximize your collaborative efficiency using this version and why it’s still a vital tool in the Trimble Tekla ecosystem. Why Multi-User Mode?

The multi-user system allows several detailing professionals to access the same master model simultaneously. Unlike traditional "copy and merge" workflows, this real-time environment ensures:

Single Source of Truth: All work is saved to one master model on your file server.

No Duplicates: Eliminates the risk of controlling or tracking multiple model versions.

Instant Coordination: Users are immediately aware of others' progress, reducing onsite errors. Key Features of Version 2.3.20

Version 2.3.20 focuses on stability and seamless connectivity within a Local Area Network (LAN).

Multi-Instance Capability: You can run multiple instances of the server on a single machine by assigning different TCP ports (default is 1238).

Efficiency for Large Teams: A single service can handle multiple models, though performance is best when models are distributed across separate services if the team size is large.

Service-Based Operation: The server runs as a Windows service, meaning it starts automatically with the computer and requires no manual login to remain active. Best Practices for Peak Performance

To keep your multi-user environment running smoothly, follow these industry-standard best practices:

Version Uniformity: Ensure every user is on the exact same Tekla Structures version, service pack, and environment.

Clean Cache: Regularly synchronize and keep local cache folders updated to prevent lag.

Network Speed: Since model data is stored centrally, a fast, reliable LAN connection is mandatory for good performance.

Sequential Saves: Remember that the model locks during opening, saving, and numbering; coordinate with your team to avoid bottlenecking these operations. Multi-User Server vs. Model Sharing: Which is for you?

Mastering Collaboration: A Guide to Tekla Structures Multi-User Server 2.3.20 Conclusion: Which One Should You Run Today

In the world of Building Information Modeling (BIM), seamless collaboration isn’t just a luxury—it’s a necessity. For structural engineers, detailers, and fabricators using Tekla Structures, the Multi-User Server 2.3.20 remains a foundational tool for teams working simultaneously on a single model.

While newer cloud-based solutions like Tekla Model Sharing have gained popularity, many firms continue to rely on the Multi-User Server for its stability within local area networks (LAN) and its straightforward setup. What is Tekla Structures Multi-User Server 2.3.20?

The Multi-User Server is a small service application that runs on a central computer (server) and manages access to a Tekla Structures model. Version 2.3.20 is a specific update designed to ensure compatibility across various Tekla versions while fixing critical bugs related to model locking and synchronization.

Essentially, it acts as a "traffic cop." When multiple detailers are working on the same high-rise or industrial project, the server ensures that two people don't try to modify the exact same part at the exact same time, preventing data corruption. Key Benefits of Version 2.3.20

Low Latency Performance: Because the server operates on your internal network, data transfer is incredibly fast compared to cloud syncing, making it ideal for large, complex models.

Model Integrity: Version 2.3.20 includes refined protocols for "saving" and "refreshing," ensuring that when a user saves their work, all other users receive the update without the model crashing.

No Subscription Fees: Unlike Tekla Model Sharing, which often requires a per-user license or "credits," the Multi-User Server is generally included with your Tekla Structures license, making it a cost-effective choice for localized teams. Installation and Setup Best Practices

To get the most out of Multi-User Server 2.3.20, your IT environment should be optimized. Here is the standard workflow for a successful deployment: 1. Server Requirements

The server application is lightweight. You don't need a high-end workstation to run it; a dedicated "always-on" PC or a standard Windows Server instance will suffice. Ensure the server has a static IP address to prevent connection drops. 2. Port Configuration

The Multi-User Server typically communicates through Port 1238. You must ensure that this port is open in your server’s firewall and that the client workstations can "ping" the server over this port. 3. Version Consistency

While the server version 2.3.20 is backward compatible with many versions of Tekla Structures (e.g., 2017 through 2021), it is vital that all detailers working on a specific model use the same version and Service Pack of Tekla Structures to avoid database conflicts. Common Troubleshooting Tips

Even with a stable version like 2.3.20, users may encounter "Locked Model" errors. Here is how to handle them:

The "Ghost" User: If a user’s computer crashes, the server might still think they are active. In the Multi-User Server administration tool, you can manually disconnect inactive users to release the locks.

Active Directory Issues: Ensure that all users have Read/Write/Modify permissions to the folder where the model is stored. The Multi-User Server manages the logic of the model, but Windows manages the file access.

Log Files: Always check the xs_multiuser_server.log file. It provides timestamped data on who joined the session and why a save might have failed. Is Multi-User Still Relevant?

With the rise of Tekla Model Sharing (Cloud), some wonder if the Multi-User Server is obsolete. The answer is no. For projects where data security prevents cloud storage, or for offices with high-speed internal networks but inconsistent external internet, the Multi-User Server 2.3.20 remains the most reliable way to deliver a project on time. Conclusion

The Tekla Structures Multi-User Server 2.3.20 is a "set-it-and-forget-it" tool that powers high-intensity detailing environments. By centralizing your model management and following basic network protocols, your team can focus on what matters most: accurate detailing and clash-free construction.

Troubleshooting Common "23 vs 20" Server Issues

Part 9: Is it still relevant in 2025+?

You might wonder: If Tekla has Trimble Connect and Cloud Sharing, why stick with Multi User Server 23 or 20?

The answer: Latency and control.

  • Cloud sharing requires an internet connection and is slower for large IFC files.
  • Multi User Server (23/20) runs entirely on your LAN. With 1GbE, the latency is <1ms.
  • Fabrication shops with legacy drawing templates (that break in newer Tekla versions) rely on version 23 as their "production workhorse."

Furthermore, the Multi User Server does not require monthly subscription fees (unlike Cloud Collaboration). Once you buy the permanent license for Tekla 23 (if you have an old perpetual license), the server is free.
