Use this dialog box to specify the settings to use when creating an alignment by horizontal regression analysis through a series of objects.
Specifies the type of source objects (COGO Points, Feature Lines, 2D Polylines, or 3D Polylines) from which to create the horizontal regression alignment.
Specifies that the alignment is created through a single path of regression points. For COGO Points, select from the drop-down menu. Click
to select feature lines or polylines.
Use this option to create an alignment from centerline sample data.
Specifies that the alignment is created between two paths of regression points. For COGO Points, select from the drop-down menu. Click
to select feature lines or polylines.
Use this option to create a centerline alignment between sample data of the either the edges of pavement of a road, or the left and right rails.
This step is optional. If you choose to select a Path 2, the output of the regression will be the CENTERLINE between Path 1 and Path 2.
Specifies the name of the alignment. Each alignment must have a unique name.
Specifies a site for the alignment. Select a site from the Site list.
Specifies the type of alignment you are creating: centerline, curb return, miscellaneous, offset, or rail. Use these alignment types to categorize data based on alignment function. For example, select the centerline type for a road centerline, the rail type for a railway, or the miscellaneous type for other uses, such as a utility conduit.
Displays the current style. Click the arrow to select another alignment style: Basic, Existing, Intersection Basic, Layout, Offsets, Proposed, or Standard.
Specifies the station value that is assigned to the beginning of the first alignment entity created.
Displays the default alignment label set. You can either accept the default label set, or use the list to select a different one from the drawing.
Displays the layer on which the alignment object is created. Click the arrow to select another layer.
Specifies the spiral type to use in the best fit alignment. For more information, see About Spiral Definitions.
This value is populating the design speed field of the resulting alignment.
Specifies the direction of the alignment. When Positive, station numbering increase along the alignment. When Negative, station numbering decreases.
