Autodesk Civil 3D 2020.4 Update

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

Fixed Issues

Autodesk Collaboration for Civil 3D

• Added the DataShortcutsSourceCheck system variable to change the behavior of warnings when saving to a mapped drive on a Nasuni Edge Appliance.
  When set to 0: Source entities are not checked and the warnings occur on the host client after the source file is saved in the source client.
  When set to 1: Source entities are checked and the warnings occur when the source entities are actually changed.
• Improved performance when saving a drawing with unloaded external references.
• Fixed a stability issue that occurred when opening a drawing from BIM 360 that contained unloaded xrefs to drawings that contained xrefs to each other.

Corridors

• Improved performance when opening a drawing that contained a corridor that referenced a subassembly PKT file that was not imported.

Data Shortcuts

• Fixed an issue in which setting the data shortcuts working folder to a read-only folder would cause Civil 3D to close unexpectedly.
• Fixed a stability issue that could occur when repairing data shortcuts.
• Fixed an issue in which data shortcuts could not be loaded while using the Always Available Offline setting in Windows 10 on folders on a network location.
• Improved stability when saving a data shortcut source drawing that contained a corridor while both the host drawing and the source drawing were open at the same time.

ESRI ArcGIS Data Workflows

• Fixed an issue in which the values of the StartInvert and EndInvert properties for pipes in a published ArcGIS layer were not correct. To resolve this issue, the StartInvert and EndInvert properties have been replaced by StartInvertElevation and EndInvertElevation.
• Fixed an issue in which the Shape property created from publishing a pipe network from Civil 3D to ArcGIS prevented the pipe network from being imported back into Civil 3D. To resolve this issue, the Shape property has been replaced by PipeShape.

Hydraflow Extensions

• Fixed an issue in which a high elevation caused incorrect culvert calculation results in Hydraflow Express.

Miscellaneous

• Improved stability when using the Save or Save As commands to save a drawing.
• Fixed a stability issue that occurred when using the REFEDIT command to edit multiline text in an xref then saving the drawing.

Object Enabler

• Improved stability when saving a drawing that contained catchments in AutoCAD Map 3D with the Civil 3D Object Enabler installed.

Pipe Networks

• Fixed an issue in which pipes with a slope of zero were ignored when finding the outfall structure.
• Fixed an issue in which the outfall was not shown in the gravity network analysis report.
• Fixed an issue in which the EGL results were different when Inlet Analysis was not selected in the Analyze Gravity Network dialog box.
• Fixed an issue in which pipe slope was calculated by the 3D length instead of the 2D length in a gravity network analysis report.
• Fixed an issue in which structure depths were not updated on the Details page of the Analyze Gravity Network dialog box after changing the invert elevation of a pipe.
• Fixed an issue in which the Manning's n value would not be updated on pipes after clicking Apply in the Analyze Gravity Network dialog box.
• Fixed an issue in which critical depth was shown as 0 instead of N/A in a gravity network analysis report.

Plan Production

• Improved performance when plotting multiple sheets.

Points

• Fixed an issue in which the transformation settings that were specified in the Drawing Settings dialog box were not retained when a drawing was saved and reopened.

Profiles

• Fixed an issue in which a Multiply Owned Object error message was displayed.

Reference Templates

• Fixed an issue in which a Multiply Owned Object error message could be displayed at the command line when editing a label style that was referenced into the drawing from a reference template.
