As a result of detailed information from customers who used the Customer Error Reporting Utility, a number of issues in the following areas were identified and fixed in this update:

Back to top

This update includes the resolution of over 70 issues. This section of the readme documents the resolved issues that previously caused loss of data, unexpected failures of AutoCAD Civil 3D, or reflect a change in functionality.


  • AutoCAD Civil 3D no longer closes unexpectedly when you insert a layout from a drawing template file.
  • AutoCAD Civil 3D no longer closes unexpectedly when you open a corrupted drawing using the OPEN or RECOVER command.
  • AutoCAD Civil 3D no longer closes unexpectedly when you run the LIST command on AutoCAD Land Desktop entities.
  • When you reopen an AutoCAD Civil 3D drawing that contains an inserted drawing, you no longer lose any Civil objects from that drawing.


  • Sample lines of an alignment that is a data referenced object no longer disappear when you use the RECOVER command to open the drawing containing such alignment.
  • The computational methods for Bi-quadratic, Bloss, and Sinusoidal spirals have been corrected. The updated computational methods will be applied to Bi-quadratic, Bloss, or Sinusoidal spirals when you open existing drawings.
  • The German version of AutoCAD Civil 3D 2010 now has the option to create a new alignment when an existing alignment is widened.


  • The .NET API CodeSetStyleItem::PayItems() method now works as expected.
  • Styles created using the COM or .NET API now appear in the Toolspace Settings tree without a manual refresh.
  • Custom subassemblies can now be used from any folder (as was the case with previous releases), instead of having to be located in the default AutoCAD Civil 3D subassembly location.

Corridor Design and Subassemblies

  • Corridor sections are now displayed properly when using the corridor section viewer along spirals in the alignment.
  • AutoCAD Civil 3D now behaves as expected when switching from paper space to model space, and then closing the Corridor Properties dialog box.
  • Retaining wall subassemblies (such as the RetainVerticalWall subassembly) now behave (draw) as expected when the Top Height parameter is set to zero, or close to zero.

Cross Section Views

  • Existing section view band labels are no longer erased when you update a section view group band set. Previously, if you used the Section View Group Properties > Change Band Set option to add a new band, the labels in existing bands were removed.
  • Section view band labels are now appearing in the correct locations after you move or delete bands. Previously, if you used the Section View Group Properties > Change Band Set option to move bands up or down or to delete bands, some of the remaining labels would not appear in the correct locations.

Grading and Feature Lines

  • The transition from a grading group to a surface now works as expected. No spikes in elevation appear at points where the transition crosses surface triangles.
  • Enhancements to the duplicate line removal tools and AUDIT/RECOVER tools were added to improve drawing recovery capabilities.

Hydrology Features

  • AutoCAD Civil 3D no longer closes unexpectedly when you import an STM file with a line that contains more than 126 characters.
  • Printing reports in Hydraflow Express now returns the expected results.
  • Plotting a schematic diagram now returns the expected results. Previously, the line weight display was distorted and the print command returned a blank document.
  • Pond tools now accept metric values.
  • Slope, Sx (ft/ft) values are now accepted for curb inlets, grate inlets, or combination inlets. Previously, a value of zero was displayed.



Object Enabler


  • When importing an STM file into a metric drawing, AutoCAD Civil 3D now detects and properly handles the drawing's SI units.
  • When exporting and then importing an STM file into AutoCAD Civil 3D, the rim elevation and pipe invert values are now calculated as expected. The values are preserved and no longer change on import.
  • In the Storm Sewers application, you can now successfully save an STM file that contains multiple outfalls.
  • In pipe-only pipe networks that are displayed in profile views, the ends of the pipes are now displayed properly when the Clean Up Pipe To Pipe Connections option is selected on the Profile tab of the Pipe Style dialog box. The ends of the pipes no longer extend beyond the profile view.

Plan Production

  • Match line labels are now correctly created only on the outside of the match line in the masked area on sheets. Previously, they were created on both sides of the match lines.


  • AutoCAD Civil 3D no longer closes unexpectedly when you view multiple points using the Object Viewer.
  • Point markers which use multi-view blocks as the symbol now appear correctly in a drawing.
    NOTE: A multiview block must be embedded in an AutoCAD block to use it as a point marker.

Profiles and Profile Views

Project Management

  • AutoCAD Civil 3D no longer closes unexpectedly when a file is saved to a Vault server with the "Create visualization attachment" option enabled.
  • Vault can now handle drawing or project folder names that contain the % character.
  • You can now use Vault Explorer to move DWG files in a Vault project when you are using AutoCAD Civil 3D As AutoCAD.


  • Layout profiles based on data shortcuts in an AutoCAD Civil 3D 2009 drawing no longer move to different locations when the drawing is opened in AutoCAD Civil 3D 2010.


  • Breakline processing during the surface paste operation now works correctly. Both the breakline edges created in the original surface and the triangle visibility property settings are retained in the target surface.
  • TIN surfaces created from contour data no longer display points with erroneous elevations.
    NOTE: If you have surfaces created from contour data and used the MinimizeSurfaceFlatAreas command in AutoCAD Civil 3D 2010, rebuild those surfaces.
  • AutoCAD Civil 3D no longer closes unexpectedly when you perform various surface operations, such as adding breaklines, displaying contour lines, or adding point groups on surfaces that contain points with unknown elevations, and the contour display settings are turned on.
