If your firm is currently on Tekla Structures Multi User Server 20 but planning to upgrade to version 23, follow this phased approach:
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.
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.
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.)

Tekla Structures Multiuser Server 2.3.20 (often referred to as version 23 20 in some contexts) is a software application that enables multiple users to work on the same 3D model simultaneously in real-time. It acts as a central hub that manages project data and prevents data conflicts during collaborative modeling. Google Groups Core Functionalities Tekla Structures Multi User Server 23 20
The server performs several critical management tasks to maintain model integrity: Access Control
: Locks the model when a user is saving or numbering to prevent simultaneous data writes. User Tracking
: Identifies client computers and keeps a live log of active users in the multi-user model. Drawing Management
: Assigns identification numbers for general arrangement and multi-drawings. Conflict Prevention
: Provides warnings if another user is currently editing a drawing or the same model object. Tekla User Assistance Installation and Setup
To deploy the multi-user environment, you must install the server package on a computer accessible to all team members via a local area network (LAN). Google Groups Package Compatibility
: The Multiuser Server version 2.3 is compatible with Tekla Structures version 17.0 and later. Service Deployment If your firm is currently on Tekla Structures
: After installation, the server runs as a background service called xs_server.exe Network Requirements
: It uses the TCP/IP protocol, typically communicating through port System Location : The default installation folder is usually C:\Program Files (x86)\Tekla Structures Multi-user Server Google Groups Model Conversion
Users can convert existing models to multi-user mode to begin collaborative work: Open the Model : Navigate to the menu and select Convert to a multi-user model Specify Server
: Enter the multi-user server name or IP address in the dialog box.
. Once finished, the model can be opened in multi-user mode from the "All models" list. Google Groups Best Practices
Tekla Structures Multi-User Server (often associated with version
for recent releases like 2020) is a service that allows multiple users to work on the same model simultaneously. Tekla User Assistance Core Content and Functionality Centralized Connectivity The Tekla Multi-User Server is a lightweight server
: 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
: A utility to start, stop, or restart the multi-user service. Tekla User Assistance Usage and Accessibility Version Compatibility
Tekla Structures releases a new major version annually (currently up to version 2024 and beyond). So why are version 23 (released 2017) and version 20 (released 2015) still heavily searched?
Critical fact: The Multi User Server version must match the client version. A Tekla Structures 23 client cannot save to a Multi User Server version 20, and vice versa. This is why you often need both installed on separate ports or machines.
| 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 |
For power users running "Tekla Structures Multi User Server 23 20" in a production environment:
Environment Variables: Add these to the server machine to increase stability:
Running as a non-admin: Do not run the server under the Local System account. Create a domain service account:
Monitoring Logs:
