Annotation

• Added an Isolate Annotations edit mode, which highlights annotation elements supporting streamlined selection and editing across multiple views. Include Categories can be used to adjust the isolated categories. Model elements are displayed as halftone and are not directly selectable.

Duct/Pipe Sizing

• Added a warning in the MEP Sizing Calculator for pipe sizes that belong to a different segment which would use a different material.

Dynamo for Revit

• Upgraded Dynamo Core version to 4.2.1. See the release notes for details.

Energy Model

• Improved the Energy Model Guide by separating analytical surfaces by Surface Type and Opening Type.

Graphics

• Added the ability to display Coordination Models and Forma Connected Client data in Accelerated views.
• Added the ability to display Coordination Model, Forma Connected Client geometry, and Wind Analysis in Accelerated views.

Reinforcement

• Improved rebar tagging so that tag leaders point only to rebar geometry visible within the view extents.

Site

• Added the ability to order road data from Forma Contextual Data Marketplace without leaving Revit.

Shared Coordinates

• Enhanced the experience of setting Draft Geolocation in cloud models and included additional options: Elevation, Rotation, and Fit Region.

Steel Connections

• Added the ability to add stiffener steel connections to Custom Connections in edit mode, save in connection templates, customize from the ribbon, and adapt to input element sizes.

User Interface

• Improved dockable panel stability and performance when opening and switching Revit models.

General

• Addressed potential security vulnerabilities.

Analytical Model

• Fixed an issue in which groups of physical elements were ungrouped when using the Analytical to Physical for Buildings script to update them.
• Fixed an issue in which the Analytical to Physical for Buildings script generated a warning message when updating a floor element.

Assembly

• Fixed an issue where the model couldn’t be saved in a specific scenario after copying a beam.

Cloud Rendering

• Fixed an issue where a cloud rendering did not match local renderings of the same view because some material assets were missing.

Column

• Fixed an issue where the steel column geometry disappeared when applying steel fabrication to Concrete Filled Steel (CFT) compound column families. A warning is displayed when fabrication is applied to multi-solid family elements.

Copy-Cut-Paste

• Fixed a performance issue where copying many in-place elements could take hours.

Data Exchange

• Fixed an issue where room geometry failed to load when opening a Revit 2026 exchange containing rooms. Room geometry now loads correctly across versions.

Duct/Pipe Sizing

• Added a warning in the MEP Sizing Calculator for pipe sizes that belong to a different segment which would use a different material.

Energy Model

• Improved the Energy Model Guide by separating analytical surfaces by Surface Type and Opening Type.

File Open/Save

• Updated the mnemonic for enabling Incremental Model Open from the File Options dialog.
• Fixed an issue that could cause the Unresolved References dialog to close unexpectedly when opening a model with missing linked files while Incremental Model Open was enabled.
• Addressed potential security vulnerabilities when opening Revit files.

gbXML

• Fixed an issue that caused gbXML Export to fail.

IFC

• Fixed an issue that prevented IFC exports to network folders.
• Improved security when importing IFC models packaged as .ifczip files.
• Improved Revit stability when opening/importing a malformed IFC file containing cyclic placement relationships.

Install

• Improved stability after installing an update while Revit was still running. The installer now requires Revit to be closed before an update can proceed.

MEP Graphics

• Improved stability while working in MEP views.

MEP Fabrication

• Fixed an issue where Route and Fill checked out extra elements after the command finished.

Pipe

• Improved stability when modifying the system after starting the pipe command.
• Fixed an issue where modify/edit tools were disabled when selecting piping branches with nested family fittings.

Project Browser

• Fixed an issue that caused the Project Browser to become unresponsive when dragging views onto sheets.
• Added the missing Collapse All item to the Project Browser context menu.

Railings

• Improved stability of railings.

Reinforcement

• Fixed an issue where the other rebar in the host would incorrectly become selectable during the first step of the Path Shape Distribution placement.
• Improved stability when propagating rebar to a host element owned by another user in a workshared model.
• Fixed an issue where rebar could not be propagated between columns in certain models.

Revit Cloud Worksharing

• Fixed a permission issue that could occur when opening a Revit Cloud Model in Forma Data Management.
• Improved resiliency of the Sync with Central and Model Open dialogs.

Revit Home

• Fixed an issue where the Revit Home title was truncated in the project title bar.

Roombook

• Improved stability when calculating and adding areas within Areabook.

Schedules

• Fixed an issue where Revit stopped unexpectedly when a schedule was edited in a specific scenario.
• Fixed an issue where the view templates applied to a schedule were not copied to a new model along with the schedule.

Sketching

• Improved stability when placing a Roof by Footprint.

Stair

• Improved stability of railings.

Structural Analysis Results Exploration

• Fixed an issue that could occur when exporting families from a model to the Content Catalog.

Structural Analytical Model

• Fixed an issue in which the Analytical to Physical for Buildings script generated a warning message when updating a floor element.
• Fixed an issue in which groups of physical elements were ungrouped when using the Analytical to Physical for Buildings script to update them.

Tags

• Improved stability when interacting with tags that use calculated parameter values from the API.
• Improved rebar tagging so that tag leaders point only to rebar geometry visible within the view extents.

UI Frameworks

• Improved stability when closing Revit.
• Fixed an issue that made docking windows to the left and right difficult.
• Improved stability when rapidly changing the Windows theme while a cloud worksharing model was opening in Revit.
• Improved dockable panel stability and performance when opening and switching Revit models.
