Tekla: Structures Multi User Server 23 20 ((free))

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.

Tekla Structures Multi-user Server 23.20 — Technical Overview and Administrator Guide Note: dates and product names follow Tekla/Trimble conventions. This document summarizes installation, architecture, configuration, operations, troubleshooting and best practices for the Tekla Structures Multi-user Server version used with Tekla Structures 23.20 (Tekla Structures 2023 series). It is intended for IT administrators and technical leads responsible for deploying and operating multi-user Tekla environments. 1. Purpose and high-level description

The Multi-user Server is a Windows service that coordinates multi-user access to a Tekla Structures master model on a network file server. It enforces locks, manages active user sessions, issues drawing and numbering IDs, and prevents conflicting saves/edits across clients. The server listens on TCP port 1238 by default and runs as xs_server.exe (installed as the Tekla Structures Multiuser Server service).

2. System components and roles

Multi-user Server host: runs the Multi-user Server service (AlwaysUp or native Windows Service). Responsible for TCP coordination and lightweight multi-user database files under ProgramData. File server / shared storage: hosts the master model folder (network share) accessible by all Tekla clients. Models must be stored on a network directory. Tekla client workstations: run Tekla Structures (same version/SP), open the multi-user model, and communicate with the Multi-user Server.

3. Version compatibility and requirements

Use the Multi-user Server version recommended for the Tekla Structures release; Tekla historically recommends using the latest Multi-user Server available for best compatibility even across Tekla versions. For the 2023 (23.20) Tekla release series, use the Multi-user Server package compatible with Tekla 2020+/2023 as supplied on the Tekla/Trimble download site. All clients in a multi-user model must run the same Tekla Structures version and service pack. All clients must use the same environment and role. Consistent configurations are recommended to avoid component/behavior differences. Tekla Structures Multi User Server 23 20

4. Port, network, and firewall

Default TCP port: 1238. Ensure bidirectional TCP connectivity on port 1238 between clients and the Multi-user Server host. Network share permissions: clients require appropriate read/write permissions to the master model share. The server host and clients should use reliable LAN connectivity; WAN or high-latency links will degrade performance.

5. Installation (summary)

Obtain the Tekla Structures Multi-user Server installer from Trimble/ Tekla Downloads for the appropriate release. Run the installer on the chosen server host; installation path is typically C:\Program Files (x86)\Tekla Structures Multiuser Server (default and not changeable during installer). The installer registers and configures the Tekla Structures Multiuser Server as a Windows service; it is set to start automatically. Installation log: C:\ProgramData\TeklaStructuresServer\xs_server.log.
