Tekla Structures Multi User Server 23 20 Online

Tekla Structures Multiuser Server 2.3 is a software application that enables multiple users to work concurrently on the same Tekla Structures 3D model. It functions by hosting a central database on a server machine, which synchronizes real-time modifications and updates across the entire team to prevent model conflicts. Key Features & Technical Details

Real-time Collaboration: Allows team members to see modifications as soon as they are made by others.

Compatibility: The multiuser server is typically used for versions of Tekla Structures up to version 2020. For newer versions, Trimble generally recommends Tekla Model Sharing as a more advanced alternative.

Network Requirements: By default, the server uses TCP port 1238 for communication.

Conversion: You can convert a single-user model into a multi-user model through the "Open" menu in the Tekla Structures setup screen. Installation & Setup

Download: The installation package is available on the Trimble User Assistance portal under the "All Downloads" section for version 2020 and older.

Server Hosting: The software must be installed on a dedicated server or a workstation that acts as the host for the multiuser service.

Client Connection: Once the service is running, users connect to the server by entering the server's name or IP address when opening a model in Tekla Structures. Tekla Structures Multi User Server 23 20 - Google Groups

4. Installation & Setup (Best Practices)

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.

Known Limitations & Considerations

Extremely large models (tens of millions of objects) can still show performance degradation; consider model partitioning or using model references.
While reconnection handling improved, very unstable networks can still cause session inconsistencies—encourage short, frequent commits.
Some features depend on matching client and server sub-versions; verify third-party integrations (plugins, custom components) before upgrading.

8. Operational workflows and guidelines

Saving: only one user can save to the master model at a time. Use the recommended save-numbering-save workflow when numbering is required (Synchronize with master model option).
Numbering: schedule numbering sessions for large models (numbering can be time-consuming).
Areas of responsibility: assign distinct model areas to users where possible to reduce conflicts.
Model history: enable collection (XS_COLLECT_MODEL_HISTORY) if model change history is desired (

Tekla Structures Multi-User Server is a background service that enables multiple users to work on the same Building Information Model (BIM) simultaneously over a local area network. Version 2.3.0.20 (often referred to as 2.3) is a specific release designed to manage concurrent write access, ensuring that changes from different team members are synchronized without overwriting each other. Core Functionality

Real-Time Collaboration: Team members can work on different parts of the same master model at the same time.

Master & Working Models: The server hosts a central "master model." Each user opens a "working model" (local view) and saves changes back to the master model to make them visible to others.

Traffic Management: The server does not handle traffic simultaneously; instead, it processes requests in a queue to maintain data integrity.

Automated Service: It runs as a Windows service that starts automatically with the computer, requiring no manual login to remain active. Key Technical Specs (v2.3.0.20) Getting started with multi-user | Trimble User Assistance

Rating: 4.5/5

A primary feature of the Tekla Structures Multi User Server 2.3.20 is its ability to facilitate real-time, simultaneous collaboration by managing centralized write access and model locking.

This service acts as a traffic controller for teams working on a shared local network (LAN). Key functionalities include:

Conflict Prevention: It automatically locks the master model when a user is saving, numbering, or editing specific objects, preventing others from making overlapping changes that could cause data loss.

Active Session Management: The server keeps a live track of all active users and their client computers, allowing team members to see who else is currently working on the project.

Automated Numbering Control: It manages the distribution of unique ID numbers for general arrangement drawings and multidrawings, ensuring consistency across all users.

Local Synchronization: Users work on a local "working model" and only synchronize their changes to the master model on the file server when saving, which helps manage network load. Multi-user system | Trimble User Assistance

The "Master.usr" File Lock

If the server crashes

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].

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].

Security Best Practices for Version 23 & 20

Neither version 23 nor 20 has modern encryption (TLS 1.2 was not standard for the server service). Therefore:

Do NOT expose the server to the internet or use VPN-to-WAN connections. Use a site-to-site VPN or SD-WAN.
Isolate on a VLAN separate from guest Wi-Fi and general corporate traffic.
Use Windows Firewall IP restrictions: Allow only known workstations’ IP addresses to connect to ports 135 and 12000-12100.
