2026.0.0
A new major RevitLookup update with official Revit 2026 support and a lot of enhancements 🎉
This release focuses on performance, a renewed UI, expanded functionality, redesigned application architecture, clearer separation of core components and user flow improvements. Let's move to the details.
General
- Revit 2026 support.
- Added shortcuts.
SSshortcut opens the Snoop Selection window. - Unlocked Ribbon buttons for document-independent actions. Some dialogs can be opened without opening a document.
- Improved context actions. Now
Deletecommand shows the number of deleted Elements from the document. - Improved exception handling. Now shows more informational messages, added more supported error types. Fixed some application crashes.
- Fixed dependency conflicts for .NET Framework versions of RevitLookup, according to tests, you should no longer encounter startup issues.
- Added AppBundle, that can be installed with all available versions in the release.
- Added user manuals, visit the Wiki for RevitLookup features.
- Added digital signature. Thanks Kinship for providing cloud services!
User Interface
Dashboard page
The Dashboard has been significantly redesigned to make it easier to understand for users unfamiliar with the Revit API.
- Added description of all actions, navigation became more intuitive and clearer.
- Added UiControlledApplication action to analyze properties and methods available when running the add-in.
- Actions now grouped according to the window size.
Summary page
Updated and improved Summary page components.
- Improved responsiveness of the whole page. RevitLookup now supports displaying large amounts of data, 100k rows will not cause freezes and glitches.
- Improved shortcuts, now the F5 key works in all cases, previously it was required to focus on an element.
- Improved filter menu. Now applying Show/hide filters does not close the menu.
- Improved tooltips. Tooltips now display more useful information, number of elements contained in the type, full type name.
- Improved search. It is now more intuitive and faster. Priority is given to the members table, the table is filtered first, then if nothing is found, the list of items is filtered. When searching the table of members, the elements with the same type will be filtered as well.
- Show Extension filter is now enabled by default.
- Patched WPF issues causing non-obvious member's table behavior.
Settings page
- Added description of all settings, navigation became more intuitive and clearer.
Unit dialogs
- Improved context menu, Copy commands are grouped into sub-menu.
Modules dialog
- Added new context menu action. Added navigation to the module directory or directly to the module file.
- Added column sorting. Click on the column header to sort.
- Improved context menu, Copy commands are grouped into sub-menu.
Application
- Adjusted default window sizes for better display due to changes in Win.UI components.
- Synchronised UI library and styles with Wpf.UI.
- Improved theme synchronization with Windows.
- Added a new high contrast theme.
LookupEngine
RevitLookup now runs on its own engine.
The engine can run outside Revit, and can be reused across the entire family of Autodesk products.
This is a pledge for the future for products like AutocadLookup, InventorLookup and others.
Isolating the engine also brings many new improvements:
- The engine is much faster than the integrated version, it allocates less memory, and supports more features.
- Added context support, now allows additional metadata to be used to resolve members.
- Fixed CLR exceptions for critical .NET Core components when evaluating members.
- New Lookup Engine API. Isolation encouraged independent use of the API in any application.
- Improved context detection, objects now understand what context they are in and provide values specific to their context, not just the active context.
- Added navigation stack, now it will be easier to add support for new unsupported parent-dependent methods.
Improvements
- Revit 2025.4 patch brings some fixes to the API, now some methods and properties are available again for use in RevitLookup:
DatumPlane.CanBeVisibleInViewDatumPlane.GetPropagationViewsIndependentTag.TagText
- Added new View extensions:
GetAllPlacedInstances
- Added new Wall method overloads by @SergeyNefyodov:
IsWallCrossSectionValid
- Added new CompoundStructure method overloads by @SergeyNefyodov:

- Visualisation now supports the new CurveLoop type, thanks @JieGou for the implementation!
Development:
- Redesigned project structure:
- Standalone LookupEngine. The LookupEngine is now a separate project, independent of RevitLookup.
- Standalone LookupEngine.UI. The LookupEngine UI is now a separate project, independent of RevitLookup.
- UI Playground for development and testing the UI outside the Revit, independently.
- Moving to Central Package Management, all dependencies are now managed in a single file.
- Moving to Central Build Management, common build configurations are now managed in a single file.
- Automatic registration of MVVM components in the service provider, no longer need to register each component manually.
- .NET 9 SDK support for development.
- Migrated to SLNX solution format, to avoid Git merge conflicts.
- Changed API for ContextMenu. Now it provides dependencies and execution context.
- Disabled PresentationFramework traces for the entire domain to address UI performance issues and freezing under an attached debugger, leaving only Critical events enabled.
- Updated Contribution guide.

Revit.ini File Editor
The Revit.ini file is a key configuration file in Revit that stores settings related to user preferences, system behavior, and project defaults.
The Revit.ini File Editor provides a simple and efficient way to manage these settings without the need for manual editing.
With this tool, users can quickly adjust Revit’s configurations to match project needs or personal preferences, making it an essential utility for both professionals and teams working with Revit.
This is our first public version, and we are excited for you to try it out for yourself!
Make sure to file issues you encounter on our GitHub so we can continue to improve it.

Dependency conflict static analyzer
Some users experience issues launching RevitLookup, often caused by conflicts with third-party plugins (see issue #269).
To help resolve these issues, we've introduced new tools that allow you to analyze, identify and upgrade problematic plugins causing crashes.

Addins dependency isolation. End of DLL hell
In this release, RevitLookup now runs in an isolated container for addin dependencies.
This new capability prevents conflicts and compatibility issues arising from different library versions between plugins, ensuring a more stable and reliable environment for plugin execution.
This enhancement uses the Nice3point.Revit.Toolkit to manage the isolation process, effectively eliminating DLL conflicts.
By integrating this package, RevitLookup ensures a consistent and predictable user experience.
Detailed description how it works: https://github.com/Nice3point/RevitToolkit/releases/tag/2025.0.1
Dependency isolation is available starting with Revit 2025.
Note that the isolation mechanism is implemented by an additional library that must be loaded into Revit at first startup for it to work.
Therefore, if your other plugins use Nice3point.Revit.Toolkit, it must be updated to version 2025.0.1, which introduces this feature

RevitLookup ✨1000 Stars on GitHub
We're proud to share that RevitLookup has achieved 1000 stars on GitHub!
This milestone is a testament to its value and the dedication of our community.
Thank you for helping us reach this landmark!
To celebrate it, we are excited to introduce a major new feature in this release that will transform your interaction with models, offering a deeper understanding of the geometric objects that constitute your models.
Introducing Geometry Visualization
This release includes comprehensive Geometry Visualization capabilities, enabling users to visualize various geometry objects directly within the RevitLookup interface.
In Revit, geometry is at the core of every model.
Whether you are dealing with simple shapes or intricate structures, having the ability to visualize geometric elements can significantly improve your workflow, analysis and understanding of the BIM.
To illustrate the power of these visualization capabilities, here's a glimpse of the geometric objects you can now explore directly within RevitLookup:
| Geometry | Illustration |
|---|---|
| Mesh |  |
| Face |  |
| Solid |  |
| Curve |  |
| Edge |  |
| BoundingBox |  |
| XYZ |  |
For detailed documentation, visit: https://github.com/jeremytammik/RevitLookup/wiki/Visualization
