These sample lines represent the sections. For more information about creating an alignment, see About Creating Alignments. Depending on the sample line style, a line or multi-segment line is drawn across the alignment that represents the section.
Depending on the sample line style, sample lines are drawn along the alignment, cutting across the alignment at the specified corridor stations. These sample lines represent the corridor sections. Do one of the following: Press Enter to select from a list of alignments. In the drawing, click the desired horizontal alignment. Specify a sample line group. A sample line must belong to a sample line group. Review the default styles. Change them if necessary. Click OK. If a sample line group already exists in the drawing, the Sample Line Tools toolbar is displayed.
To assign a sample line group to the sample line, select the sample line group in the list. Do one of the following: At the command line, specify a station by entering the desired station value. In the drawing, use the cursor tooltip to find the station along the alignment. The rotated sample line rotates back to a perpendicular orientation 3 to its parent alignment, but retains the length to which it was stretched or contracted.
To use parameters to edit sample line location and length In the drawing, click the sample line you want to edit. In the Edit Sample Line dialog box, review the parameters for each vertex of the sample line by clicking Previous Vertex and Next Vertex. At the vertex you want to edit, do one or more of the following: In the Name field, change the name of the sample line. In the Sample Line Segment Length field, change the length of the swath width to the desired distance in ground units or click to pick a new segment length from the drawing.
In the Sample Line Station Value field, change the sample line station value or click to pick a new station value from the drawing.
To use grips to edit a sample line In the drawing, click the sample line you want to edit. Use the diamond-shaped center grip to move the sample line to a new location along the alignment.
Use the square-shaped end grips to stretch lengthen or shorten , move, or rotate segments. Use the triangular-shaped grips at the ends of segments to stretch lengthen or shorten each segment while keeping its relative direction. You can double-click a Style cell in the table to select the Section Style. The Sample Line Tools toolbar is displayed.
A Specify Station prompt is displayed on the command line. This option creates a sample line at each station found in the corridor model. The sample lines are created, and the Sample Line Tools toolbar is available for defining additional lines, if desired. To continue this tutorial, go to Exercise 2: Creating Section Views. In this exercise, you will create a set of sample lines along the alignment.
