# To define additional points

Use Additional points to define design features like key positions for a drainage system or road cross sections.

You can key in points or import them from a CSV file or LandXML file.

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.
