Autodesk Civil 3D 2022.1 Update

Alignments
Added support for exporting and importing speed tables for all alignment types using LandXML.
Fixed an issue in which closing the Alignment Properties dialog box by clicking the Cancel or OK button with no change to the alignment would cause a corridor to redraw if the alignment was used as a target for the corridor.
The time to open drawings has been reduced by 20% for drawings that contain long alignments with labels.
API
Fixed an API issue in which the AlignmentRailInfo.RailWidth parameter was not accessible for rail offset alignments.
Fixed an API issue in which GeneralSegmentLabel.Create() failed on closed polylines.
Fixed an API issue in which the AppliedSubassembly parameter did not take the reference parameter into consideration. The main change was to correct the behavior of ValueAsObject in IAppliedSubassemblyParam. Now the same DesignValue/Value behavior as in the Parameter Editor in the Cross Section View Editor can be kept.
A CorridorSlopePattern created though the API will now have the default StartStation and EndStation set to the baseline alignment's start and end station, and assigning StartStation and EndStation after that will succeed.
Assemblies
Fixed an issue in which a dialog box couldn't be resized when adding a subassembly to an assembly.
Autodesk Collaboration for Civil 3D
Fixed an issue in which an XML file that was used as surface data in a drawing was uploaded to two different locations in BIM 360.
Fixed an issue in which the version of a large surface (.mms file) was increased unexpectedly when opening its host drawing from Autodesk Docs.
Autodesk Connector for ArcGIS
Fixed an issue in which the cursor was not active in the drawing after connecting to the Autodesk Connector for ArcGIS.
Corridors
Fixed an issue in which temporary alignments and profiles that were created for feature lines were shown in the corridor targets mapping list.
Fixed an issue in which the offset subassemblies for a corridor were not considered when creating a corridor surface.
Fixed an issue in which a corridor was not brought back to up to date when using the UNDO command after performing an edit that would cause the corridor to be marked out of date.
Fixed an issue in which additional objects from other baselines were shown in the Corridor Section Editor.
Fixed an issue in which a corridor required a rebuild or was marked out of date when creating a corridor surface in the Corridor Properties dialog box.
Fixed an issue in which intersections and corridors became out of date when saving a drawing that contains them.
Fixed an issue in which corridors were unnecessarily regenerated when there was no geometry change for corridor surfaces in the Corridor Properties dialog box. For example, this would occur if the corridor surface selection was cleared, or if the surface name or style in the Corridor Properties dialog box was changed.
Fixed an issue in which the profile of a secondary alignment was deleted unexpectedly when creating corridor regions for intersections.
Fixed a stability issue that would occur when creating a corridor with a grid surface.
Fixed a stability issue that would occur when opening a drawing with a corridor that targeted a grid surface.
Fixed a performance issue related to invoking the corridor surface target dialog box. The time to invoke the dialog box has been improved from 15 seconds to 1 second.
The Rebuild All command will now rebuild corridors based on their dependency relationships so that all corridors will be up to date after using the command.
The time to rebuild a corridor has been improved by 20% if the corridor uses feature lines or 3D polylines as targets.
The time to rebuild a corridor has been improved if error messages about the subassemblies that are used are displayed in the Event Viewer when the corridor is rebuilt.
Improved performance when opening a drawing that contained a corridor that referenced a subassembly PKT file that was not imported.
Improved the performance of opening corridor cross section views by 30%.
Reduced unexpected out of date corridor notifications caused by changes of horizonal baselines and corridor surfaces.
Reduced unexpected out of date corridor notifications caused when clicking OK to close the Assembly Properties and Subassembly Properties dialog boxes when no parameters were changed.
Data Shortcuts
Fixed an issue in which opening a data shortcut source drawing would switch to the original drawing after the source data was opened.
Fixed an issue in which a corridor data shortcut was referenced incorrectly.
Fixed an issue in which the current data shortcut project was reloaded when clicking Cancel in the Set Working Folder dialog box.
Fixed an issue in which the data shortcut reference out of date status was not updated after the broken reference was repaired.
Fixed an issue in which corridor baselines could not be referenced using data shortcuts.
Fixed an issue in which duplicate data shortcuts with the same name were generated when repairing a broken data shortcut or reference.
Enhanced the data shortcuts Repair Broken References command to provide an option to fix the broken reference by using the data shortcut with the same Name for a Handle Only reference or by using the data shortcut with the same Handle for a Name Only reference.
Improved performance by not loading the most recent data shortcut project when starting Civil 3D. There is a new system variable LoadRecentDSProjectOnStartup which can be set to 1 to enable the old behavior.
Significant performance improvements have been made when working with large data shortcut projects. For an Autodesk Docs-based dataset with 500 data shortcuts the following improvements were observed:
- The Set Working Folder command was 30 times faster, as was loading a project on startup of Civil 3D and loading an associated project when opening a drawing.
- The Set Data Shortcuts Project Folder command was 20 times faster.
- The Refresh command was 60 times faster.
- The Repair Broken Shortcut command was 5 times faster.
Depending on the project size, the improvements might differ. Local area network (LAN) projects will see slightly lower but still significant improvements as well.
Dynamo for Civil 3D
Fixed an issue in which a Dynamo script failed after closing the Dynamo Player.
Fixed an issue in which files in the same folder as the drawing file would be removed accidently after running a Dynamo script and publishing to ArcGIS.
Added a Dynamo Binding setting in Dynamo for Civil 3D to turn trace data on and off.
Updated Dynamo Core to Dynamo 2.12.
General
Added the capability to show out the of date shield mark on the collection parent level in the Prospector tree.
Added a tooltip that is displayed while hovering the cursor on an out of date shield in the Prospector tree.
Fixed an issue in which exporting simple geometry as KML from Civil 3D resulted in geometry at the wrong location in Google Earth.
Improved shared views to show the name of objects in the Model Browser.
Fixed an issue in which Civil 3D would lose focus if the AutoCAD Properties window was open.
Grading
Improved the display of glyphs that appear at the vertices of a feature line when the Grading Elevation Editor window is displayed. The display of glyphs is affected by the values of Resolution, Scale, and Layout in the Display Settings of Windows. The display is best when you use the recommended system settings and the quality of the display will decline as the value of Scale and Layout increases.
Improved usability when editing PIs or elevation points in the Grading Elevation Editor by keeping the focus on the edited points.
Intersections
Fixed a stability issue in which grip editing an intersection would cause Civil 3D to become unresponsive.
Fixed an issue in which intersections and corridors became out of date when saving a drawing that contains them.
Parcels
Fixed a stability issue that would occur when deleting parcel segments and then using the UNDO and PURGE commands.
Performance
Multiple performance enhancements have been made in Civil 3D. The percentage of the improvement on drawings will vary since the drawings contain different content, thus all the improvements mentioned below are calculated based on the sample datasets that were used for benchmark testing. Those sample datasets are shared by customers, and are real world projects. The overall time taken to run the tests on all these customers' datasets was reduced by 50.3% when compared against the time taken using Civil 3D 2022.0.
1. Multi-Core Plotting from AutoCAD 2022 reduced the time of publishing from 8 minutes to 2 minutes.
2. Open drawing and regen time has been reduced up to 14% to 40% for drawings that contain corridors.
3. Regen time has been reduced up to 14% for drawings that contain long alignments with labels.
4. Invoking the Corridor Section View Editor has been improved up to 80%.
5. Open drawing and regen time has been reduced between 14% and 40% for drawings that contain multiple section views.
6. Opening drawings has been improved up to 61% for drawings that contain a large number of pipe network catalogs with user defined attributes.
7. Opening drawings has been improved up to 80% for drawings that have missing subassemblies.
8. Rebuilding a corridor improved up to 20% if corridors are using feature lines or 3D polylines as targets, depending on the number of vertices in the feature lines or polylines.
9. Switching from model space to paper space have been improved up to 35% if the viewport in paper space contains sections since surfaces, pipes, structures, and alignments are not drawn.
