CIBSE verified
CIBSE's pioneering Software Verification Assessment program, the first of its kind in the UK, has verified our electrical demand, cable sizing, and protective device calculations. You can confidently rely on the accuracy and efficacy of your calculations.
General Updates:
- This update introduces an optimized Protective Device Database foundation, deliveringfaster performance and immediate access to our latest device libraries. We’vere-engineered the backend to ensure your workflow remains seamless and future-ready.Note: Users must update to this version to access the new database and future devicelibraries.
- Microsoft ended support for Windows 10 on 14 October 2025. To maintain the security ofyour system and ensure uninterrupted compatibility with Trimble Electrical Designer, westrongly recommend all users migrate to Windows 11.

Improvements
- Enhanced the underlying AI architecture for Trimble Assistant to support more complexreasoning and faster resolution of user queries.
Notice of AI Interaction: We want to inform you that you are interacting with an Artificial Intelligence (AI) system. This AI agent service utilizes generative AI technologies to support your experience and success with the software.
Provider: Trimble Inc.
References: Trimble AI Statement and Principles
Purpose and Intended Use: This AI system is designed to improve user efficiency by answering Trimble Electrical Designer product-related questions. This AI system is not intended for use in, and may not be used in, any manner or purpose that would be considered “high-risk” under the EU AI Act.
How It Works: The assistant combines information retrieval from Trimble resources with generative language models to provide answers. The AI acts strictly as an advisory support tool and does not make autonomous operational or design decisions on your behalf.
Data Processed & Privacy Controls: The system processes your interactions (chat prompts) and all data is handled in strict accordance with the Trimble Privacy Notice.
Limitations & Required Human Oversight: Generative AI systems can occasionally produce inaccurate, incomplete, or unexpected results (often referred to as "hallucinations"). Because ProDesign facilitates complex engineering and mathematical workflows, you must independently review and verify all AI-generated calculations, results, and design suggestions before relying on them. The Trimble Assistant is designed to augment, not replace, professional engineering judgment and certified design practices.
Feedback: If you encounter unexpected or inaccurate outputs, please use the Thumbs Up/Down feature within the Assistant interface to help us continuously improve the system safely.
- [MEPEL-7563] Data Entry tool now retains the selections across tabs of the same component. For example - if you select two cables in the ‘Details Tab’, the same cables will be selected in the ‘CPC Tab’.
Resolved Bugs
- [MEPEL-10852] Resolved a bug where the selected AFDD appeared blank in the data entry and component editor due to project data inconsistencies.
- [MEPEL-12432] Fixed a bug where Modular Board Schedule Reports would be blank.
- [MEPEL-12439] Fixed a bug where the project would not open when being saved with a file path containing ‘non standard latin’ characters.

Upgrade procedure
In order to upgrade your software to this new version, you need a Trimble ID. The ProDesign suite of applications will notify you when an application update is available for User Licence. For further support, please see the following Technical Assistance section.
Software Update Notifications
The ProDesign suite of applications will notify you when an application update is available for download.
In case your software has received any calculation updates, you will be notified with a “Calculation Service Version Update'' during the first instance of calculation.
In case your software has received any calculation updates, you will be notified with a “Calculation Service Version Update'' during the first instance of calculation.
Named User Licensing
All products within the Trimble Electrical Designer Suite (ProDesign, Protect, SingleCable and PowerNet) are now powered through named user licensing. This means that users have dedicate licences assigned to their own Trimble ID and ensures everyone uses the same, up-to-date calculations and content. This empowers you to significantly reduce the risk of design discrepancies that occur when different versions of the software are used within your team.
To learn more about this and moving to a Trimble Electrical Designer subscription, call our sales team on 01908 608833 (opt 2). If you have any questions regarding the licence management and accessing the product, please contact our support team via the details below.
Technical Assistance
Our Technical Support team uses a support tool which allows them to view and control users’ machines remotely. This is only ever undertaken with the user’s permission – and while being supervised by the user.
Our applications have a menu option link to the support web page containing details of this assistance should it be required. For more information, please contact our support team via Amtech Support@Trimble.com or call +44 (0)1908 608833 and then choose Option 1, and then Option 1 again.

Trimble MEP makes Building Information Models (BIM) a reality by delivering solutions that transform disconnected workflows between stakeholders into a coordinated, constructible and actionable building model. To ensure a building is constructed in the most efficient way, the Trimble Constructible Process goes beyond BIM by creating models that use actual manufacturer content, allow for prefabrication and full clash detection, connect stakeholders to coordinate in real-time and bring the model directly from the computer to the field. This process optimizes the entire design, build and operate lifecycle.
