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].

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

Rating: 4.5/5

Tekla Structures Multi-User Server (Version 2.3.2.0) is an essential utility for local design teams who need to collaborate on the same 3D structural model in real-time. While newer cloud-based solutions like Tekla Model Sharing are available, the Multi-User Server remains a reliable, cost-effective choice for teams working on a shared local network. Key Features & Functionality

Real-Time Synchronization: Allows multiple users to connect to a central database, enabling them to see updates from colleagues as soon as they save their work to the master model.

Centralized Master Model: The system maintains one "master model" on a server, while each user works in a local "working model." This structure minimizes the risk of data corruption.

Low Performance Requirements: The server software is lightweight and does not require high-end hardware; it can even run on the same machine as the Tekla License Server. Part 5: Common Error Codes and Fixes When

Multi-Instance Support: Version 2.3 allows for setting up multiple server instances on a single computer by assigning different TCP ports (default is 1238), which helps in organizing different projects or teams. Pros and Cons Getting started with multi-user | Trimble User Assistance

Tekla Structures Multi-User Server (version 2.3.20) is an on-premises coordination service that enables multiple team members to work on a single 3D building information model simultaneously over a Local Area Network (LAN). While newer cloud-based technologies like Tekla Model Sharing

have largely superseded it for global teams, the Multi-User Server remains a stable, cost-effective choice for local, office-based teams. Tekla User Assistance 🏗️ Core Functionality

The server acts as a "traffic controller" for your project data. Master Model: One central model is stored on a file server. Working Models: Each user opens a local copy on their computer. Conflict Prevention:

The server manages write-locks, ensuring that when one person saves or runs numbering, others are momentarily queued to prevent data corruption. Real-Time Awareness:

Users can see changes made by colleagues every time they save their local model to the master. Google Groups ⚙️ Technical Specs & Requirements

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

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
