# To add template positions

After adding templates, you must specify the station at which the Roads software starts to apply each template. A template is applied at the start station and the values defining each string are then interpolated linearly (applied on a pro rata basis) from that point to the station where the next template is applied. See Template positioning examples.

To add template positions to the selected road definition:

1. Tap Template positioning. The Apply template screen appears.
2. To specify a new position at which template(s) should be applied:
   1. Tap Add.
   2. Enter the Start station.
   3. In the Left template and Right template fields, select the template to apply.

      To interpolate the template for this station from the previous and next templates in the road definition, select <Interpolate>.

      If you do not want to apply a template, for example to create a gap in the road definition, select <None>.

   4. Tap Store.
3. Continue adding positions where templates should be applied, as required.

4. When you are done, tap Close.

5. Tap Accept.

6. To select the interpolation method for calculating cross sections between template positions, select Elevation or Cross slope. Tap Accept.

   The Road cross section interpolation by field is added to the road Options screen. To change the interpolation method for the road, tap Options in the road components screen.

7. The software returns to the Apply template screen. Tap Accept.

8. Enter the other road components, or tap Store to store the road definition.
