The following issues have been resolved in the Autodesk Civil 3D 2019.3 Update:

Autodesk Subassembly Composer

• Improved performance when opening rail subassembly PKT files that use cant.
• Fixed an issue in which the superelevation of subassemblies created with the Subassembly Composer failed to be incorporated into a corridor.

Corridors

• Fixed an issue that caused the outer corners of corridors to not clean up correctly where there were straight-straight intersections in the baseline.
• Added the ability to generate slope stake reports for data referenced corridors.

Data Shortcuts

• Fixed an issue in which a data referenced corridor was not reported as being out of date after the associated data referenced alignment was deleted.
• Improved performance when synchronising data shortcut references.
• Fixed an issue that prevented creating corridor data shortcut references.
• Fixed an issue in which data referenced alignments were created as the wrong alignment type when creating data referenced corridors that had dependent non-centerline alignments.
• Fixed an issue in which nested alignment data shortcut references appeared to be broken after data shortcuts were deleted.
• Fixed an issue in which nested data referenced alignments and corridors reported being out of date.
• Added a warning to instances when the source of a corridor data shortcut reference needs to be rebuilt.
• Fixed an issue in which pipes lost their connections to structures when synchronising data referenced pipe networks after locking layer 0.

General

• Fixed an issue where in some environments, applying customisation files caused Civil 3D to close unexpectedly on startup.
• Updated a zlib component to correct a vulnerability issue.

Mapcheck Analysis

• Improved stability when performing a mapcheck analysis on a parcel with curved edges.

Labels

• Corrected an annotation issue along parcel segments created from alignments.

LandXML

• Fixed an issue that caused alignments to be added to sites when they were imported from a LandXML file.

Mapcheck Analysis

• Improved stability when performing a mapcheck analysis on a parcel with curved edges.

Pipe Networks

• Fixed an issue in which pipes and structures used the units specified in the pipe network feature settings instead of the units specified in the pipe and structure feature settings.
• Fixed an issue in which a pipe centerline that was referenced into a drawing using an xref was displayed using the colour of the xref layer.

Points

• Fixed an issue in which the point data in a .csv file parsed incorrectly during the point import process when the data contained user defined properties.
• Fixed an issue that caused properties specified on the Query Builder tab of the Point Group Properties dialogue box to change after attaching an xref.
• Fixed a graphical issue that could occur near the cursor when creating points.

Profiles

• Fixed an issue in which saving a drawing that has crossing objects in a profile view reported an error on the command line.

Quantity Takeoff

• Fixed a pay item formula volume calculation issue in QTO Manager.

Surfaces

• Fixed an issue where the volume of a volume surface shown in a surface level legend table didn't match the volume shown in the surface properties.
• Fixed an issue where the volume of a volume surface shown in a surface elevation legend table was incorrect when the elevation analysis contained a range with a negative elevation value.

Survey

• Fixed an issue in which survey figure data imported incompletely.
• Fixed an issue where accessing survey figure properties in model space from within a locked layout viewport would cause the viewport scale to change.

Traverse Editor

• Fixed an issue in which the syntax for an angle was not accepted as a valid input format in the Traverse Editor. For example, 3..12°34'142.0 cm (56'') would be reported as invalid.
• Fixed an issue in which an angle with a degree symbol was treated as a bearing instead of a turned angle.
• Fixed an issue in which docking or undocking the Traverse Editor would open the Unsaved Changes dialog box.
• Improved functionality of the Traverse Editor by retaining the calculated distance from point to point when saving a balanced TRV2 file.
• Improved the numerical precision in the TRV2 file to match the Traverse Editor and Drawing Settings.
• Removed trailing zeros and added numerical delimiters for clarity when displaying traverse adjustment results.
• Fixed scaling issues in the Traverse Editor user interface when using 4K displays.
• Fixed a precision issue when closure summaries were calculated using a vector from the point of closure to the last calculated point in the adjusted traverse.
• Added scale factor and rotation angle values to the report for a Grant Line adjustment.
