Tekla Structures Multi-user Server 2.3.20: Technical Overview and Configuration
The Tekla Structures Multi-user Server 2.3.20 is a specialized network service designed to facilitate real-time collaboration on 3D structural models. It serves as a management hub that coordinates simultaneous access to a single "master model," allowing multiple team members to work concurrently without the need for manual model merging. 1. Core Functionality and Architecture
The multi-user system operates on a TCP/IP network and consists of three primary components: the Multi-user Server, the File Server (hosting the master model), and Client Computers.
Model Synchronization: Each user works on a local "working model." Changes are only updated to the master model—and made visible to others—when the user performs a save operation.
Operational Control: The server performs critical administrative tasks, including:
Locking the master model during saving or numbering to prevent data conflicts.
Assigning unique identification numbers to new model objects and drawings.
Tracking active users and issuing warnings if multiple users attempt to edit the same object or drawing. 2. System Requirements and Installation
While the multi-user server software is lightweight and has low CPU usage, the overall performance depends heavily on network stability and the hardware of the file server hosting the model. Tekla Structures Multi User Server 23 20 - Google Groups

Mastering Collaboration: A Guide to Tekla Structures Multi-User Server 2.3.20
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.

Title: Keeping the Team in Sync: A Look Back at Tekla Structures Multi User Server 23 & 20
Intro In the fast-paced world of structural detailing and BIM, "collision" shouldn't just refer to rebar and ducts—it should never refer to file versions. Before the cloud became the default answer, Tekla Structures introduced a robust on-premise solution to keep teams working harmoniously: The Tekla Structures Multi User Server.
Today, we are taking a technical deep dive into versions 23 and 20. While these are not the latest releases (the current numbering has since evolved), many legacy projects and specific client workflows still rely on these stable versions.
Why Multi User (MU)? The Multi User Server allows multiple detailers to work on the same model simultaneously. Instead of "Check-out/Check-in" locks, Tekla uses a live database. When you save, your changes are immediately visible to everyone else (provided they refresh).
Version 20 (v20.0 – v20.9) Released during the "golden era" of Tekla’s transition from v19, Version 20 was a workhorse.
Version 23 (v23.0 – v23.9) Version 23 marked a maturity point. By this release, Trimble had ironed out the kinks of the previous UI overhaul.
Setting up a MU for v20/v23 (A Quick Refresher) If you are resurrecting an old server for a legacy project, remember these three rules:
The "Auto-Save" Trap One major behavior difference between v20 and v23:
Should you still use them?
Final Verdict Version 20 was the reliable diesel engine. Version 23 was the fuel-injected upgrade. Neither has the fancy web interface of today's solutions, but when you need to get 5 detailers modeling a concrete core wall on a tight deadline without paying for cloud credits, the Tekla Multi User Server 23/20 is still a legend.

In the Tekla release cycle, version 20 (2015) and version 23 (2017) are considered "Long Term Stability" (LTS) releases. Many fabrication shops still refuse to upgrade past version 23.0 because later versions changed the database schema. Consequently, Tekla Structures Multi User Server 23 20 environments are the most common hybrid setups found in active fabrication shops today.
Upgrade to 23.20 for improved stability, performance, and diagnostics if you manage active multi-user models, but follow the checklist: test in staging, ensure client compatibility, and verify network and hardware meet recommended specs.
(If you want, I can produce a concise upgrade plan tailored to your environment—server specs, model sizes, and number/locations of users.)
