Fixed Issues
General
- Addressed potential RFA Out-of-Bounds Read Vulnerability in Autodesk Revit.
Coordination Model
- Fixed a Coordination Model changes processing glitch and potential unexpected close of Revit that could occur when working with the same Coordination Model in two Revit sessions side-by-side or in two Revit projects in the same Revit session.
- Improved the numbers reporting for modified and deleted elements in Coordination Model Changes.
Import/Export Data Exchange
- Resolved an issue affecting placement and scaling of certain objects linked into Revit via the Data Exchange Connector for Revit.
Export DWG/DXF
- Fixed an issue where hatches were exported incorrectly to CAD formats if the patterned elements were transparent in the Revit view.
Parameters
- Corrected editing of the "Tilt Angle" within the type editor on objects such as lighting fixtures.
Properties Dialog
- Added a new option in Revit.ini "DisableParamSortInMPPAndEditTypeDialog" in section "UserInterface" which sorts parameters in the order of creation, to match the behavior in earlier releases.
Reinforcement
- Fixed an API issue where updaters subscribed to geometry changes are not triggered when free form rebar constraints are edited.
Revit Cloud Model (workshared)
- Updated Revit to load upiconfig.xml from a new location (C:\Program File\Autodesk\Revit XXXX\UPI).
- Fixed the issue where cloud models with a long path are not available for linking.
- Fixed an issue with the Revit Link API to ensure cloud models initiated via API can be published as expected.
Stair
- Fixed an undefined behavior when the cut plane level is equal to the height of the top nosing (tread).
Steel Connections
- Resolved instabilities when opening corrupted models.
User Interface
- Fixed an issue that Revit UI became unresponsive in some cases with Windows 11.
