Description

Creates Horizontal and 3D alignments to represent a reference system used to position linear objects in space.

Note: You can offset Horizontal Alignments. The result of the OFFSET command on Horizontal Alignments is a non-associative polyline.
Horizontal Alignment is created by specifying points of intersection (PI) of the tangent polygon. Curves are drawn automatically between the tangents.
Note: The DEFAULTCURVETYPEHA system variable specifies the curve type to be used when create a new horizontal alignment or adding new PI. The default value is Auto Spiral-Curve-Spiral.

Options within the command

Select TIN surface
Allows you to select a TIN surface used to drape Horizontal alignment and to create 3D alignment.
Note: Two 3D alignments are created: one represents the projection of the Horizontal Alignment to the TIN Surface and second represents the Vertical Alignment, which is calculated based on the Vertical tolerance parameter.
Pick pi point
Allows you to pick the PI points for your Horizontal alignment.
Note: If Select TIN surface option was previously selected, the 3D alignment is automatically generated.
Undo
Undoes the last PI point.
Specify start station
Allows you to define the start station when start creating a new alignment.
