Autodesk Infraworks 2021.2.1

ArcGIS Data Integration
Fixed an issue where a layer could not be published after update service name.
Fixed an issue where an ArcGIS layer could not be imported successfully with the clip-to-model option selected.
Fixed an issue where a layer published to ArcGIS Enterprise portal could not be opened directly.
Bridges and Tunnels
Fixed an issue with toggle behavior in parametric decorations that caused attribute toggles to be stuck on.
Fixed an issue where after adding cross frames to a bridge, the selection of bridge objects disappeared.
Fixed an issue where running refined bridge analysis a second time while having an analysis PDF report open did not give feedback to the user.
Fixed an issue so the road gizmo is now active when a new bridge is drawn.
Civil 3D DWG Import
Fixed an issue where road profiles which contained parabola with almost identical in and out grade were unable to be imported.
Fixed an issue of parabolas in road profiles getting removed when there were free parabolas that had almost identical in and out grade.
Component Roads
Fixed an issue that could occur if a road was selected when all data sources were deleted in the Data Sources panel.
Fixed an issue where road options at IMX tab and DWG tab of the Configure Road dialog box were not translated.
Improved the performance of adding roads in models containing tunnels.
Fixed an issue with the component decoration split tool that occurred when multiple clicks happened while the model was refreshing.
Fixed an issue in which only part of the lane marking was seletable if the road assembly was added in componnet roads.
Fixed an issue of incorrect geometry of alignment when importing anchored floating curves in IMX.
Fixed an issue when importing roads from Civil 3D from either DWG or IMX that caused some vertical curves to be discarded so that they showed as just PVIs in the Profile View.
Coordinate Systems
Fixed an issue with the "Which coordinate system should I choose?" link in the New Model dialog that caused the link to always go to the English page regardless of the Language setting.
Create, Edit, Delete Core Feature
Fixed an issue where the Content picker was shown when starting a Draw Tool from the toolbar, such as drawing a conceptual road or water area.
Fixed an issue that occurred when rapidly editing features.
Cross Sections
Fixed an issue that caused Right of Ways not to be displayed in the Cross Section View in circular curves and other tangent sections.
Fixed an issue with Cross Section View buttons that would cause difficulty switching between views.
Drainage Design
Fixed an issue in which the IDF icon was not shown in Size Drainage Network dialog.
General
The Open Model dialog changes to the correct size and the text in the dialog and also should adjust according to the Hi DPI scaling settings.
Home
Fixed an untranslated string on the new Home page.
Fixed the date and time format on the Recent tab of the new Home so that it responds to the Region settings of the operating system.
Model Builder
Fixed an issue when accessing Model Builder in mainland China.
Fixed an issue when importing a SHP file in Model Builder. If the polygon is not imported at the expected location, re-export the file from Civil 3D and use the MAPEXPORT option to perform coordinate conversion to LL84.
Selection
Fixed an issue where the component highlighting and selection could highlight or select the incorrect component.
Site Design
Fixed an issue that caused the triad gizmo and bounding box to not be enabled in 2021.1.
Stack
Fixed an issue in which the right edge of the Stack was cropped and information was illegible.
Stylization
Fixed a thumbnail image in the DrawStylePicker.
Watershed & Streams
Fixed an issue in which the selected station range was not shown in watershed anlaysis.

General
Fixed when selecting a Bridge and keeping it selected led to the memory increasing until InfraWorks ran out of memory or the user unselected the bridge.
Avoided a crash when the configure dialog box was opened for an Imported Civil drawing and InfraWorks model was synced from BIM 360.
Added more checks for consistency on importing corridors to avoid failures.
Fixed a failure to render bridge girders on corridors comprised of multiple assemblies.
Fixed failures to generate Parametric 3D due to some Python scripts issues.
Fixed foundation elevations that were incorrect after Shift-F5 in certain cases.
Updated InfraWorks to use the latest SQLite version: 3.32.3.
Fixed some terrain issues that would prevent the user from exporting a tunnel to IMX.
Plugins
Avoided errors and skip cutting terrain when a tunnel had no meshes.
Fixed excessive curve smoothing in Revit for variable width tunnels.
Avoided cutting failures when generating decks or girders.
Ensured UI strings are localized.
