To add templates

A template defines a cross section of the tunnel at a point across the tunnel to define how wide it is at different points. Add a template for each change in width. The template may consist of any number of surfaces.

Templates must be defined in a clockwise direction. Surfaces can be open or closed.

To define a template for the selected tunnel definition:

  1. Tap Templates.
  2. To add a new template:
    1. Tap Add.
    2. Enter the template name.
    3. In the Copy from field, select whether to copy an existing definition from a tunnel or another template, into the template.

      To create a template library, define a tunnel that only contains templates.

    4. Tap Add.

  3. To define a new surface:
    1. Tap Add.
    2. Enter the surface name.
    3. In the Copy from field, select whether to define the surface by offsetting an existing surface.
    4. Tap Add.
  4. To define the start point for the surface:
    1. Tap New.
    2. In the Horizontal offset and Vertical offset fields, enter the values that define the Start point.
    3. Tap Store.

    The element appears in the graphical view.

    If you have started a survey, you can tap Measure to measure positions within a tunnel to define elements in a surface. If no surface elements have been defined, tap Measure to define the Start point. If the surface consists of one or more elements, tap Measure to define the end point of a line element.

  5. To add further elements to the surface:
    1. Tap Add.
    2. Select the Element and enter the required information. The information required depends on the selected element:

      Line elements

    3. Tap Store.

    If you have started a survey, you can tap Measure to measure positions to define further elements in the surface.

  6. Continue adding elements as required.

    Each element is added after the selected element.

    Use the Start, Prev, Next and End softkeys to view other elements in the template.

  7. To save the template and return to the Surfaces screen, tap Accept.

  8. Add or select a different surface to edit, or tap Accept to return to the list of templates.
  9. Add or select a different template to edit, or tap Accept to return to the list of components for the selected tunnel definition.
  10. Enter the other tunnel components, or tap Store to store the tunnel definition.
