: The project manager should occasionally open the model in "Single-user mode" to run Diagnose & Repair tools on the database.
Remember the golden rule of Tekla Multi User: Communication saves conflicts. Use the server not just as a tool, but as a protocol. When version 23 eventually reaches end-of-life, you have a robust migration plan already tested for version 20 legacy models.
It maintains the locking mechanism for the central model database, ensuring that two users cannot modify the exact same structural object (like a specific steel beam or concrete column) at the exact same split-second. Tekla Structures Multi User Server 23 20
Do you still have a v23 MU server running in your server room? Let us know in the comments below.
Trimble offers two primary methods for collaboration: and Tekla Model Sharing . Understanding their differences helps determine the right fit for your organisation. Multi-User Server Tekla Model Sharing Network Requirement Local Area Network (LAN) / VPN Internet connection Infrastructure Local server required Cloud-based (Trimble Connect) Best For Teams working in the same office Distributed teams across regions Data Transfer Continuous lock/unlock requests Periodic "Write Out" and "Read In" changes Licensing Free utility tool Paid subscription per user 🚀 Best Practices for Peak Performance : The project manager should occasionally open the
Version 20 is older but renowned for its low overhead. Many precast plants still run version 20 due to custom plugins that never updated.
Setting up version 23 20 is a straightforward process. When version 23 eventually reaches end-of-life, you have
: 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
Even in a well-configured environment, issues can arise. Here is a troubleshooting checklist for common problems.
| Feature | Tekla 20.0 | Tekla 23.0 | |--------|-----------|-----------| | | 2015 | 2016 | | Server OS Support | Windows Server 2008 R2 – 2012 R2 | Windows Server 2012 – 2016 | | Tekla Client Compatibility | TS 20.x only | TS 21.0 – 23.1 | | .NET Framework Required | 4.0 | 4.5.2+ | | Automatic User Disconnect | Manual only | Configurable timeout | | Performance for Large Models | Moderate | Improved (better lock handling) |
