What's new in VIKTOR (June 2025)

IFCView now support IFC 4.3

You can now also load IFC 4.3 files in the IFCView, supporting the latest version of the IFC specification!

This update ensures your VIKTOR apps stay compatible with the most modern BIM workflows. No changes are required on your end; just load your IFC 4.3 files as you normally would, and everything will work out of the box.

Visit the documentation to learn how to implement an IFCView in your VIKTOR app.

Control which views users see

By default, all views in an app are visible, regardless of what users select. But sometimes, you only want to show results if a certain parameter is set.

With the new visible argument, you can control which views are shown. Either hide or display views dynamically to create a cleaner and more relevant user experience.

For example, if your app lets users choose between running a single load case or an optimization, you can now show different result views based on that choice.

Curious how to implement it? Check out the documentation.

Community Spotlight

This month in the community spotlight, we have the Facade Configurator, built by Team ASAPrompters during the UCODE25 Prompting Challenge.

This LLM-powered tool helps users explore facade design options by adjusting building parameters, facade systems, and design choices like materials, window-to-wall ratio, and sun shading. As you tweak the inputs, the app instantly updates the cost and carbon footprint, alongside a visual preview. 

The Facade Configurator was the winning tool in the category Best UX. Congratulations to Sam Holla (B2architecten), Alexey Matyunin (TU Delft), and Xinzhi Jiang (Hercuton)! 🏆
