Creating Sample Lines

Product Documentation

View Original

Create sample lines along an existing horizontal alignment.

Sections are cut along each of the samples lines for a specified set of surfaces. Corridor sections are created when you sample a corridor.

You can create one or more sample lines that are associated with an alignment. In Toolspace, in the Prospector tree, the sample lines are children of an alignment and appear in the hierarchy in the Sample Line Groups collection.

Note

When you create sample lines for the first time for an alignment, you are prompted to create a sample line group in which to place the sample lines. This group also contains the list of surfaces, corridors, corridor surfaces, and pipe networks (if any), based on the alignment so that you can select the data source(s) to be sampled.

In the drawing, sample lines can be labeled with annotations, including stations and other information.

The section can be displayed using the section view. For more information, see Working with Section Views.

Tutorial Exercise: Creating Sample Lines

To create a perpendicular sample line, of a specified swath width, across an alignment at a specified station

  1. Click Home tabProfile & Section Views panelSample Lines.At the Command prompt, enter CreateSampleLines.

    The cursor changes to pick mode. You are prompted to select an alignment.

  2. Do one of the following:
    • Press Enter to select from a list of alignments.
    • In the drawing, click the desired horizontal alignment.

    For information about creating an alignment, see Creating Alignments.

  3. Specify a sample line group. A sample line must belong to a sample line group. Do one of the following:
    • If this is the first sample line group you are creating in the drawing, the Create/Edit Sample Line Group dialog box is automatically displayed. 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.

    The cursor changes to station pick mode (default). You are prompted to select a station.

  4. 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. Click the station.
  5. Do one of the following:
    • At the command line, enter the left swath width. Press Enter.
    • In the drawing, at the desired distance, click the first point, which defines the start of the left swath width. Click the second point, which defines the end of the left swath width (that is, the length).
  6. Do one of the following:
    • At the command line, enter the right swath width. Press Enter.
    • In the drawing, at the desired distance, click the first point, which defines the start of the right swath width. Click the second point, which defines the end of the right swath width (that is, the length).
  7. Right-click to end the By Stations mode.

    Depending on the sample line style, a line is drawn perpendicular across the alignment at the specified location and length. This sample line represents the section.

Note

For left and right swath widths, you can attach an alignment, such as a right-of-way alignment. This enables you to define variable sample line widths. If you later use the Edit Swath Widths for Group tool on the Sample Line Tools toolbar, all sample line widths will be extended or trimmed to the group’s widths.

To create a sample line or multi-segment sample line by picking points on-screen

  1. Click Home tabProfile & Section Views panelSample Lines.At the Command prompt, enter CreateSampleLines.

    The cursor changes to pick mode. You are prompted to select an alignment.

  2. Do one of the following:
    • Press Enter to select from a list of alignments.
    • In the drawing, click the desired horizontal alignment.

    For more information about creating an alignment, see Creating Alignments.

  3. Specify a sample line group. A sample line must belong to a sample line group. Do one of the following:
    • If this is the first sample line group you are creating in the drawing, the Create/Edit Sample Line Group dialog box is automatically displayed. 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.

    The cursor changes to station pick mode (default). You are prompted to select a station.

  4. On the Sample Line Tools toolbar, in the sample line create method list, click , which selects Pick Points On Screen. You are prompted to select a start point.
  5. In the drawing, use the cursor tooltip to find the start point. Click the start point.
  6. Do one of the following:
    • In the drawing, click an end point on the opposite side of the alignment. Finish the pick point session by right-clicking. Press Enter.
    • In the drawing, click one or more points to define the sample line (section) with the final end point on the opposite side of the alignment from the start point. Note that if the final end point is not on the opposite side of the alignment from the start point, the sample line is interpolated to attach to the centerline of the alignment.
  7. Do one of the following:
    • Continue picking points on screen to draw more sample lines.
    • Right-click to end the Pick Points On Screen mode.
    Note

    When you create a sample line that is located between corridor stations, the data shown in the section is interpolated between the preceding and succeeding stations.

    Depending on the sample line style, a line or multi-segment line is drawn across the alignment that represents the section.

To create perpendicular sample lines, by a range of stations, across an alignment at specified station intervals

  1. Click Home tabProfile & Section Views panelSample Lines.At the Command prompt, enter CreateSampleLines.

    The cursor changes to pick mode. You are prompted to select an alignment.

  2. Do one of the following:
    • Press Enter to select from a list of alignments.
    • In the drawing, click the desired horizontal alignment.

    For information about creating an alignment, see Creating Alignments.

  3. Specify a sample line group. A sample line must belong to a sample line group. Do one of the following:
    • If this is the first sample line group you are creating in the drawing, the Create/Edit Sample Line Group dialog box is automatically displayed. 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 desired sample line group in the list.

    The cursor changes to station pick mode (default). You are prompted to select a station.

  4. On the Sample Line Tools toolbar, in the sample line create method list, click , which selects By Station Range.

    The Create Sample Lines - By Station Range dialog boxis displayed.

  5. Review the default settings. Change them if necessary. Click OK. Note that the station range defaults to the entire length of the alignment.

    Depending on the sample line style, sample lines are drawn along the alignment, cutting across the alignment at the specified intervals. These sample lines represent the sections.

To create perpendicular sample lines across an alignment at specified corridor stations
