To Create an Alignment From Graphic Entities

Create an alignment from selected lines, curves, or polylines.

This command converts a series of graphic elements to an alignment, and optionally adds curves between straights.

1. Draw one or more lines, curves, or polylines in the drawing.
2. Click Home tabCreate Design panelAlignment drop-downCreate Alignment From Objects Find.
3. Select the graphic elements and press Enter.
   Note: Enter XREF at the command line to select elements from within the xref drawing. See AutoCAD Help for more information about external drawing references.
4. Press Enter to accept the alignment direction or enter R to reverse the direction.
5. In the Create Alignment - From Objects dialog box, enter a unique name for the alignment.
6. Enter an optional description.
7. Enter a starting chainage value.
8. On the General tab, specify the following settings:
   • Site

     Specify a site with which to associate the alignment or accept the default <None>. For more information, see About Sites.

   • Alignment Style
   • Alignment Layer
   • Alignment Label Set
9. If you want to apply design criteria to the alignment, click the Design Criteria tab and specify a Starting Design Speed to apply to the alignment starting chainage.

   This design speed is applied to the entire alignment. Additional design speeds can be applied at other chainages after the alignment has been created. For more information, see To Change Alignment Design Speed and Design Criteria Properties.

10. To associate design standards with the alignment, select the Use Criteria-Based Design check box.

    On the Design Criteria tab, specify the following settings:

    • Use Design Criteria File

      Select this check box to associate a design criteria file with the alignment. The default design criteria file location and the Default Criteria properties become available when you select the check box.

      Note: The first design criteria file found in the C:\ProgramData\Autodesk\C3D <version>\eng\Data\Corridor Design Standards\<units> directory is used by default when the criteria-based design feature is used.
    • Use Design Check Set

      Select this check box to associate a design check set with the alignment. The design check set list becomes available when you select the check box. Select a design check from the list.
