Autodesk Civil 3D 2020.6 Update

Autodesk Civil 3D 2020.6 Update addresses release includes updated features, performance enhancements, and fixes for Autodesk Civil 3D 2020.

New Features

Many of the new features listed in the help refer to Civil 3D 2020.5 Update improvements.

Gravity Analysis

  • Includes a new setting called Pipe Length Type which can be used to specify the pipe length type to use for the analysis calculations.

Fixed Issues

Autodesk Civil 3D 2020.6 includes the product fixes included in the previous updates for Civil 3D 2020. The many API improvements and fixes are listed at the bottom of this post.

Alignments

  • Fixed an issue in which alignment minor station labeling did not work as expected.

Autodesk Collaboration for Civil 3D

  • Improved performance when switching data shortcut projects for projects that are stored in BIM 360, downloading source files only when required.
  • Fixed an issue that caused the host and consumer drawings in the cloud to be updated when dismissing the "Data shortcut definitions may have been changed" notification.

Catchments

  • Fixed an issue in which the catchment exclusionary property would exclude catchments from other catchment groups.
  • Fixed an issue in which the value of catchment exclusionary property was always 'False' after reopening the drawing.

Corridors

  • Fixed a stability issue that would occur when trying to open the corridor Rehab Manager with the German Country Kit installed.
  • Improved stability when restoring corridor bowties.

Cross Sections

  • Fixed an issue in which parts of corridor section labels would be moved to the wrong location in a section view when the source sample line became skewed.
  • Fixed an issue in which the default label set for section view creation would not be held when switching to another alignment while creating section views.

Data Shortcuts

  • Fixed an issue in which a data referenced alignment that was used as a reference for a pipe network was not updated after the alignment name was updated in the source drawing.
  • Improved performance when switching data shortcut projects for projects that are stored in BIM 360, downloading source files only when required.
  • Fixed a stability issue that would occur if the Shortcuts folder is readable, but its contents such as ShortcutsHistory.xml are not readable.
  • Fixed an issue in which data shortcuts were created at a temp address which was caused by an automatic save in AutoCAD.
  • Fixed an issue in which the surface definition source xml was saved at a temp address which was caused by an automatic save in AutoCAD.
  • Updated the Data Shortcuts Editor to show the variable DSSysVar in the path.
  • Fixed an issue in which ETransmit did not include Civil 3D data shortcuts.
  • Fixed an issue in which the referenced pressure network name changed unexpectedly after synchronizing data shortcuts.
  • Fixed an issue in which Civil 3D would lock up (and the DWG file would become read only) when saving a source drawing with a shared data reference.
  • The issue was caused by multiple Civil 3D sessions trying to read the data shortcut source drawing while it was being saved in another session.
  • Please make sure the system variable DataShortcutsSourceCheck is turned off (set its value to 0) in Civil 3D on every computer working on the same project.
  • Note that when the system variable DataShortcutsSourceCheck default value is set as 0, a notification will be displayed in the host/consumer drawing whenever the source drawing is saved, even without any entity/geometry change.

Drawing Import/Export

  • Fixed an issue in which the Export to DGN setting Use remapping file would not work for Microstation Connection.
  • Fixed an issue in which nested xref drawings did not show exploded objects after using the Export to DGN command.
  • Added the ability to use Microstation Connect when exporting a Civil 3D drawing to DGN when both Connect and V8i are installed.
  • Added a new system variable named DGNOpenAfterCreation to keep Microstation open after a drawing is finished being exported to DGN.
  • Added the ability to use the user's UCF when exporting a Civil 3D drawing to DGN when Microstation is installed.
  • Fixed a stability issue that would occur when exporting a Civil 3D drawing that has xref drawings that contained points.
  • Added a setting to set a sleep time so that MVBA has time to run after exporting a drawing to DGN.

Feature Lines

  • Fixed a performance issue that would occur when selecting feature lines while the Properties Palette was open.
  • Fixed an issue in which feature lines that were used as corridor baselines and located in a site would disappear from the site.
  • Fixed an issue that caused invisible alignments to be created while updating a feature line which is the baseline of a corridor. Related to this issue, customers are encouraged to use the PurgeHiddenAlignsfromSites command on drawings that have feature line-based corridors.
  • If you do not run the PurgeHiddenAlignsfromSites command prior to editing a feature line in a feature line-based corridor, and you subsequently have issues with the feature line that is used in the corridor (for example, it is missing and you can no longer select it), undo your changes or close the drawing without saving it, reopen it, and then run the PurgeHiddenAlignsfromSites command.
  • Errors that will lead to missing feature line issue are automatically detected and fixed when opening a drawing. This operation will only run when Civil 3D detects a potential error in the drawing.
  • Fixed an issue in which PI points would be added at incorrect locations of a feature line when using the _AeccFeatureLineCrossing command when the intersected point is far away from the feature line in 3D space.

Hydrology

  • Fixed an issue in which a blue line was shown in the culvert analysis results in the Hydraflow Express Extension.
  • Improved culvert analysis performance in the Hydraflow Express Extension.

LandXML

  • Fixed an issue in which LandXML import would create an additional copy of an imported pipe network.
  • Fixed a performance issue that would occur when importing surfaces from a LandXML file.
  • Added an option to the LandXML Import Settings to control whether to add breaklines. Import performance is improved when the option is set to Off.

Miscellaneous

  • Fixed a stability issue that could occur when opening a drawing.
  • Support for Autodesk Docs and the new rebranded Desktop Connector has been added. The User Interface now refers to Autodesk Docs instead of BIM 360.

Pipe Networks

  • Fixed an issue in which velocity values reported in different tables in the gravity network analysis report were not consistent due to precision differences in the calculations.
  • Added a warning message in the Event Viewer when a structure height is edited so that the height is outside the allowed range specified by the part's Rim to Structure height.
  • Added the ability to store structure type and tail water data for a null structure.
  • Fixed an issue where the style, rules, and other settings could not be changed in a parts list for a null structure.
  • Fixed an issue in which the pipe network label anchor settings didn't work as expected.
  • Added the ability to select the pipe length for gravity network analysis.
  • Added the ability to change a structure type from "None" to "Outfall" when using the Analyze Gravity Network command.
  • Fixed an issue in which some of the output was incorrect in Analyze Gravity Network report.
  • Added the ability to support more anchor points in plan and profile labels for pipes.

Profiles

  • Added the ability to support pipe and pressure pipe expressions in profile view bands.

Quantity Takeoff

  • Fixed an issue in which Quantity Takeoff was affected by an empty material subcriteria setting.

Reference Templates

  • Fixed an issue in which Civil 3D would close unexpectedly or a code set style would be corrupted when attaching a particular template to a particular drawing.

Reports

  • Enhanced the AeccReportAlignPoints command so that using the NETLOAD command to load AeccTransportationX.dll and restarting Civil 3D is not necessary in order to run the report. You can also enter ReportAlignPoints at the command line to run the command.
  • Fixed an issue in which many design profile types were excluded from the Transportation Extension reports.
