Issues Resolved for Autodesk Civil 3D 2007

This Service Pack resolves the following issues:



  • Slope values for the following subassemblies now migrate correctly: LinkOffsetAndSlope, LinkSlopeAndVerticalDeflection, LinkSlopeToElevation, LinkSlopeToSurface, LinkWidthAndSlope.
  • When creating cul-de-sacs that are modeled with the corridor object, the offset from the arc now computes correctly when the offset point is located at exact center of the arc.
  • Accessing the Subassembly Properties dialog box no longer causes the program to become unresponsive.
  • Civil 3D 2006 drawings containing subassemblies with slope values now open successfully.


  • Transitions using relative elevation criteria are now created correctly. Previously, the projections were sometimes created with incorrect distances.
  • Several issues that prevented drawings containing problematic grading geometry from opening have been resolved.
  • A performance issue with grading into a surface has been resolved. For example, grading a pond into a surface now completes in a more acceptable amount of time.
  • Pasting a grading surface into a corridor surface then saving now responds as expected.
  • An issue with opening a drawing containing grading feature lines, after closing another drawing, has been resolved.



  • An issue with pipes in a Profile View when connected structures are displayed as a solid has been resolved. Note that in the Structure Style dialog box, the "Enable part masking" check box is now hidden when the structure is being displayed as a solid. It is recommended that you use the “Display as boundary” option in the Profile tab of the Structure Style dialog box. The performance of this option is significantly faster than when the “Display as solid” option is used. Note that the “Display as boundary” option is the default for new styles, but existing styles from Autodesk Civil 3D 2006 are set to “Display as solid".
  • An issue with structures displaying as blocks in Profile Views has been resolved. Masking now works as expected.
  • An issue with drawings containing pipe networks that are parallel to sample lines has been resolved. Drawings containing pipe networks that are parallel to sample lines no longer terminate unexpectedly.
  • An issue with pipe network references creating dependent object data (such as alignments and profiles) has been resolved. Now when you create a pipe network reference, dependent objects do not get created.
  • Points modified in the Prospector tree and drawn by point groups other than the All Points point group now update appropriately.
  • An issue with using the Point Editor to change point styles, point label styles, or point layers has been resolved. The Point Editor now responds appropriately when you change these items.
  • An issue with opening a new drawing using a 2006 drawing template has been resolved. Drawings that have an external data reference in the point settings can now be updated successfully.
