Tekla Structures Multi User Server 23 20 May 2026
| Issue | Likely Cause | Solution | |-------|--------------|----------| | “Server not found” | Firewall blocking port | Allow ports 27000–27001 | | Model won’t open | Version mismatch | Match client & server versions | | User locks not releasing | Stalled session | Restart server service | | Slow response | Too many users | Reduce concurrent users to ≤15 |
The system operates on a Master-Slave architecture:
Tekla Structures Multi-User Server 23.20 is a service that enables multiple users to work on the same Tekla Structures model simultaneously. It acts as a central hub where the model is stored, ensuring that all changes made by different team members are synchronized in real-time. Google Groups Key Features and Functions Real-Time Collaboration
: Team members can see updates and revisions as soon as they are made, preventing conflicts and ensuring everyone uses the most recent version. Workflow Optimization
: Centralizing the database saves time and reduces errors compared to managing individual model copies. Default Port : By default, the multi-user server communicates via TCP port 1238 Google Groups Installation and Versioning Version Compatibility
: While the specific "23.20" string often appears in older forum threads, Trimble typically provides version-specific installers. For newer versions (like 2020 and beyond), the installer can be found on the Trimble Downloads Administrative Access
: You must have administrator rights on the server computer to run the installation wizard. System Requirements
: The server software generally requires a Windows-based operating system; for example, the subscription tool specifically requires Windows 11 Microsoft .NET Framework 4.8 for modern versions. Tekla User Assistance Setting Up the Server : Obtain the multi-user server installation file from Tekla Structures Multi User Server 23 20
: Run the installer on a dedicated server or a computer that remains powered on for team access. : Ensure that port
Comprehensive Guide to Tekla Structures Multi User Server 2.3.2.0
The Tekla Structures Multi User Server 2.3.2.0 (often referred to as version 23 20 in specific documentation) is a critical utility for engineering and detailing teams working on complex 3D structural models. It enables multiple users to access and modify a single master model simultaneously within a local area network (LAN). Key Benefits of Multi-User Mode
Working in multi-user mode allows teams to streamline their workflows by:
Real-Time Collaboration: Team members see updates and revisions as soon as they are saved to the master model, ensuring everyone is aligned.
Conflict Prevention: The server manages a queue for operations like saving and numbering, preventing data corruption and conflicts when multiple people work on the same area.
Centralized Data: All model data is stored on a central file server, reducing the risk of data loss compared to individual local copies. Installation and Setup of the Multi-User Server | Issue | Likely Cause | Solution |
Setting up the server involves installing the software on a machine that remains continuously accessible to all workstations. 1. Download and Installation
The installation package can be found on the Trimble Downloads page. While it is often associated with Tekla Structures 2020, the version 2.3/2.5 server is compatible with versions from 2017 onwards.
Default Path: C:\Program Files (x86)\Tekla Structures Multiuser Server.
Service Name: Once installed, it runs as a Windows service named Tekla Structures Multiuser Server. 2. Network Configuration
To ensure clients can connect to the server, you must configure your firewall:
Execution File: Add xs_server.exe to your firewall and antivirus exception lists.
Ports: The default port for the multi-user server is 1238. Some documentation for specific sub-versions (like 23 20) may reference port 1245; ensure you use the port specified during your specific installation. 3. Converting Models to Multi-User The system operates on a Master-Slave architecture: Tekla
To begin collaborative work, a single-user model must be converted: Multi-user system - Trimble User Assistance - Tekla
Even with proper setup, network issues can arise. Here are common solutions for Multi-User Server 23:
Before diving into the specific versions, it is vital to understand the engine. The Tekla Multi User Server is not a cloud service; it is a lightweight, on-premise server application that allows multiple team members to work on the same exact model simultaneously.
Unlike traditional file locking (where User A locks the entire file while User B waits), the Multi User Server uses model sharing logic:
The server merges these changes in real-time. It resolves conflicts line-by-line and object-by-object. Versions 23 and 20 refine this process, offering specific stability patches for large assemblies.
The Tekla Multi-User Server is a lightweight server application designed to manage access to a single Tekla model shared by multiple users. Unlike the more advanced Tekla Model Sharing, which utilizes cloud-based caching for distributed teams, the Multi-User Server is designed for Local Area Network (LAN) environments.
If the server crashes
Tekla Structures 2023 brought significant updates to the ecosystem, and the Multi-User Server component includes several refinements to ensure stability and security.
