IFC

• Enabled IFC 2x3 export to support steel elements with geometry cuts made by both Revit and Steel modifiers.

Import/Link DWG/DXF/DGN

Keyboard Shortcuts

• Updated the Keyboard Shortcuts dialog to only display commands that are available based on the current feature configuration.

MEP Fabrication

• Improved the Edit Part dialog to support double-wall seams.

Reinforcement

• Added the ability to place standard rebar shapes in 3D views.

Shared Coordinates

• Added a warning when the survey point values fall outside the Coordinate Reference System (CRS) extent during geolocation setup.

• Added a notification indicating the success or failure of setting or resetting geolocation data.

Steel Connection

• Improved the behavior of the Steel Connection dialog so that images scale proportionally with DPI.

Steel Fabrication Elements

• Enabled shape handle controllers for fabrication beams, allowing users to adjust element cutbacks directly from the canvas when cutback parameters are available.

Steel Modifiers

• Improved graphical display of contour cuts in structural steel elements.

Structural Analysis Results Exploration

• Added the ability for structural engineers to view analysis results with a modernized Results Exploration experience.

Structural Analytical Model

• Added the ability to create analytical elements by selecting grid lines or grid intersections to streamline analytical model creation and reduce placement errors.

Wall

• Allow users to choose whether Place by Room and Place by Segment select only room-bounding walls and columns.

General

• Addressed potential security vulnerabilities.

AEC Data Model

• Fixed an issue where datasets linked from Autodesk Forma displayed an incorrect PathType of Absolute instead of Cloud.
• Improved version consistency between Revit cloud model and AEC data model when the Forma Connected Client toggle status is unknown.

Autodesk Assistant

• Improved user experience by removing unsupported functionality from the UI and preventing confusion when customizing shortcuts.
• Fixed an issue where the Autodesk Assistant could not reliably apply color overrides to elements, including cases where colors appeared unchanged or were only applied one element at a time.
• Fixed an issue where the Autodesk Assistant could not apply filters to schedules when requested.
• Improved user experience by removing unsupported functionality from the UI and preventing confusion when customizing shortcuts.
• Fixed an issue where the Autodesk Assistant could produce incorrect results when asked to perform operations relative to grid lines, such as moving elements or creating section views.
• Fixed an issue where using the Autodesk Assistant to create multiple views or sheets in a single workflow could cause Revit to stop responding.

Beams and Braces

• Improved rotation for tag placed on components that are defined as Structural Framings.
• Improved Shorten so that after applying Split, it would still leave the beam extended.

Column

• Fixed an issue when creating columns without a Level Reference that would not disable the At Grids feature from the Ribbon.

Data Exchanges

• Fixed an issue where loading Data Exchanges with certain types of parameters would fail.

Design Option

• Fixed an issue that caused instability when trying to pick a plane from a different Design Option.

Dimensions

• Fixed an issue where the ribbon controls for Spot Slope appeared cut off in some localized versions of Revit.
• Fixed an issue where Revit could stop responding when working with dimensions in certain models.

Duct/Pipe Display

• Improved Union type pipe fittings with a single connector by scaling with annotation scale similar to end caps.

Energy Model

• Removed one layer from the construction 4 in face brick with 2 in insulation in the Constructions.xml to correct the U-value.

Export PDF

• Fixed an issue to notify users that background PDF export cannot start if other background tasks are in progress.

External Resource Framework

• Fixed an issue where the External Resource Add-in Error dialog could be unexpectedly displayed when opening a Revit family.

Forma Carbon

• Fixed an issue so that detached models saved in Forma Data Management show up in a new collaborative folder in the Project Browser.

Forma Connected Clients

• Fixed an issue where unnecessary permissions were required to disconnect a model from a scenario.
• Fixed an issue where the wind estimate would not work immediately after connecting to a scenario.
• Fixed an issue that required an unnecessary element permission when working with a scenario in a worksharing environment.
• Fixed an issue that prevented Forma Building Design models from loading into Revit when the model contained unsupported geometry types.
• Fixed an issue where wind estimate results would still display after disconnecting the terrain from the scenario.

Graphics

• Fixed an issue where a large TIFF background image does not display in Accelerated views.
• Improved the stability when editing a curtain wall profile in Accelerated views.
• Improved the stability when opening large models with progressive loading in Accelerated views.
• Improved the stability of Accelerated views in worksharing scenarios.

HVAC Zones

• Fixed an issue that caused a system-zone to be deleted if an assigned space is deleted.

IFC

• Fixed an issue where exporting fabrication parts to IFC was causing larger files.

MEP Fabrication

• Fixed an issue where fabrication pipes did not route correctly when drawn on a slope, preventing automatic connection of fittings.

MEP Systems Analysis

• Fixed an issue that prevented the folder path from changing when running a systems analysis.

Parameters

• Fixed an issue where, when new unit types are downloaded, the symbols for those units will also be downloaded.

Reinforcement

• Improved performance when splicing a rebar set that already had a staggered splice connection.
• Improved stability when switching from single to custom spacing, during varying rebar set placement.

Revit Home

• Fixed an issue where the View Online command was not working on the Revit Home page.
