New Features in Autodesk Civil 3D 2020.4

The Autodesk® Civil 3D® 2020.4 Update includes the following new features and enhancements.

Design Efficiency Updates

• The Automatic Corner Cleanup Options for corridors are now separated into inner and outer corner options. These settings are available in the Edit Feature Settings - Corridor dialog box.
  

  You can use these options to independently control whether the inner and outer corners of fixed width corridors are cleaned up at tangent-tangent intersections and at tangent-arc intersections.

• Automatic corner cleanup is now supported for outer corners of fixed width corridors at tangent-arc intersections where the line is not tangent to the curve.

  For more information, see About Corner Cleanup for Corridors.

• The Results page in the Analyze Gravity Network dialog box has been updated to include a Pipe Flow column.

  If the pipe flow value exceeds the full flow value of the pipe, this column is shaded red. When you place your cursor over the cell, a tooltip is displayed that shows both the pipe flow value and the full flow capacity.

  

  For more information, see Results Page (Analyze Gravity Network Dialog Box).

Production Efficiency Updates

• Use a new setting Add Labels to Points Interpolated from DREF Corridors to control whether to add labels to points that are interpolated from data referenced corridors. This setting is available in the Edit Feature Settings - Section View dialog box.
  
  When this setting is set to On, points that are interpolated from data referenced corridors are labeled and symbols are displayed on the points.

  

  When you move the cursor over these symbols, tooltips are displayed to inform you to confirm the actual value of the label in the source drawing.

  For more information about this setting, see Edit Feature Settings - Section View dialog box. For more information about labeling corridor points, see To Label Corridor Point Codes in Section View.

• The CorridorSectionLabelsConv command has been enhanced to support converting code set labels to corridor point labels.

  A selection dialog box is displayed when you choose to convert the labels to corridor point style labels so you can select a section label set that contains a corridor points label style.

  For more information about the CorridorSectionLabelsConv command, see To Label Corridor Point Codes in Section View.

• Components for corridor point label styles have been updated to include an Anchor Corridor Point Extension option that can be selected when specifying the anchor points.
  

• You can use the new DraftingBuffer command to turn the cross section view drafting buffers off and on.

  This setting controls whether annotation and drafting elements that are within drafting buffers, and are bound with the section views, are moved with the section views if they are moved. For more information, see To Turn Section View Drafting Buffers Off and On.

Other Updates

• The .NET API has been updated with several enhancements as described in New Features in the Autodesk Civil 3D API.
