The Tekla Structures Multi-user Server (version 2.3.20) is a service that allows multiple editors to work on the same model simultaneously [2]. Unlike the newer Tekla Model Sharing (which is cloud-based), the Multi-user Server operates on a Local Area Network (LAN) [2, 5]. Key Components

The Server Application: A lightweight service (e.g., teklastructures.exe) that runs on a central host machine [2]. Tekla Structures Multi User Server 23 20

The Multi-user Model: A model stored on a shared network drive accessible to all users [4].

Client Stations: Individual computers running Tekla Structures that connect to the server IP or hostname [2, 5]. Core Workflow

Server Startup: The administrator starts the Multi-user server service on a dedicated server or a stable workstation [2].

Model Conversion: A single-user model is converted to multi-user mode by going to File > Save As > Multi-user model [5].

Active Syncing: When a user clicks Save, Tekla synchronizes their local changes with the master model on the server [5]. If two people modify the same object, the first one to save takes priority [4]. Best Practices for Stability

Consistent Versions: All users must be on the exact same Tekla Structures version and Service Pack [1, 2].

Network Reliability: Use a wired connection. Wi-Fi is generally discouraged for multi-user environments due to the risk of packet loss during saves, which can lead to model corruption [4].

Unique IDs: Ensure every user has a unique login name to avoid identification conflicts within the model history [4].

Regular Backups: Because the server does not store "versions" like a cloud service, manual daily backups of the model folder are essential [4]. Troubleshooting Common Issues

Connection Errors: Usually caused by a firewall blocking TCP port 1238 (the default port for the Tekla server) [1].

Model "Locked": This occurs if a user’s session crashes. The administrator may need to use the Multi-user Server Manager to manually disconnect the "ghost" session [1, 2]. Overview Tekla Structures Multi-User Server 23

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:

  1. Server Name, not IP (Usually): Use the machine name in Tekla’s "Multi User" dialog. Hardcoded IPs tend to break after router reboots.
  2. The "Models" Folder: Ensure the shared network folder where the TeklaStructuresModels lives has Full Control for all MU users. The server doesn't save the file; the user's PC saves it via the server's orchestration.
  3. Firewall Exception: You must open TCP port 27000 (and sometimes 27001-27009 depending on concurrent user load) on the server's firewall.

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.

: It acts as a lightweight hub that manages traffic between different users' local copies of a model and the master model stored on a server. Networking Requirements : By default, the server communicates through TCP port 1238 . This must be open on your firewall for users to connect. Component Parts : The installation typically includes: TeklaMultiUserServer.exe : The core service file. Configuration Files : Used to define specific server settings or logs. Service Manager

Why versions 23 and 20 specifically?

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.

What is the Tekla Structures Multi User Server?

Before diving into versions 23 and 20 specifically, it is crucial to understand the core concept. The Multi User Server is a separate application (not part of the standard Tekla Structures installation) that allows multiple modelers to work inside the same model simultaneously. It uses a master-client model:

Unlike file-sharing over a standard network (which corrupts models), the Multi User Server locks individual components, not entire files. This means User A can edit a steel column while User B edits a brace 10 feet away, and both save changes without conflict.

Mastering Collaboration: A Comprehensive Guide to Tekla Structures Multi-User Server 23

In the world of structural engineering and steel detailing, collaboration is the backbone of any successful project. When multiple engineers and drafters need to work on a single model simultaneously, file conflicts and data corruption become significant risks. This is where Tekla Structures Multi-User Server 23 comes into play.

While the naming convention "23 20" can be ambiguous (often referring to the 2023 version release, sometimes associated with specific build iterations or confusion with the version 20.0 legacy naming), this article focuses on the definitive Multi-User Server version 23.0 (commonly associated with Tekla Structures 2023). This guide covers its architecture, installation, configuration, and best practices for optimal performance.

Installation Steps

  1. Download: Obtain TeklaStructuresMultiuserServer230.exe from Tekla User Assistance (requires Trimble Identity).
  2. Install: Run as Administrator. Accept the license. Choose "Full installation."
  3. Firewall Configuration: This is where most failures occur. You must create inbound rules allowing TeklaMultiUserServer.exe through Windows Firewall for Private networks.
  4. Service Account: The installer typically creates a local user TeklaMS. Ensure this account has "Log on as a service" rights.
  5. Verification: Navigate to Start > Tekla Structures > Multi User Server Manager. The server status should show "Running."
