Define additional points for LandXML string roads

Use Additional points to define design features that are not part of the road design file, such as key positions for a drainage system, lamp posts, or road signs.

During stake out, you can stake additional points as needed. You can add an additional point by tapping any point in the job, or by tapping a point in any kind of linked file, including DXF, BIM, or CSV.

Alternatively, you can define additional points by editing the road. This can be useful when you want to use a large number of points contained in a separate file. To define additional points, import them from a CSV file or LandXML file. You can also key them in.

When importing points from a CSV file, two formats are supported:

  • Station and offset where each position in the file must be defined by a station and offset and, optionally, an elevation and code, in that order. See the following:

    1+000.000, 0.250, 20.345, ,
    1+000.000, -5.000, 25.345, End curb
    1+000.000, 4.500, , Lamp post
    1+000.000, 7.000, 25.294, Begin sound wall

  • Northing and easting where each position in the file must be defined by a northing and easting and, optionally, an elevation and code, in that order. See the following:

    5000.000, 2000.000, 20.345, ,
    5000.000, 2100.000, 25.345, End curb
    5000.000, 2200.000, , Lamp post
    5000.000, 2300.000, 25.294, Begin sound wall

For both file formats, where points have null elevations you can choose to use the elevation of the vertical alignment at the station value of the point.

On import northing and easting coordinates in the CSV or LandXML file are converted to station and offset values relative to the road.

To add additional points to the selected road definition:

  1. Tap Additional points.
  2. To import points from a file:
    1. Tap Import.

    2. Tap and select the file. Tap Accept.

      The imported points are listed in the Additional points screen.

  3. To key in points:
    1. Tap Add.
    2. Enter the Station and Offset for the point.
    3. If required, enter the Elevation and Code.
    4. Tap Store.
    5. Continue adding points as required.
    6. When you are done, tap Close.

    To insert a point, tap the point you want the new point to follow and tap Insert.

  4. Tap Accept.
  5. Enter the other road components or tap Store to store the road definition.
