(4) Circle
There are two ways to create a circle: 3 points and Point +R. 3 points
requires three points on the circle to create a circle. Point + R requires the
center point and radius of a circle to create it. Their usage is similar to
that of creating an arc.
(5) Alignment
There are two types of alignment: horizontal alignment and vertical alignment.
Horizontal alignment is generally composed of left arc, line and right arc. It
uses point + azimuth + length to create a line and point + azimuth + length +
R.

5.5 Road
eField User Guide V7.5.0
5.5.1 Road stakeout
eField Roading is a module that allows to create and manage road design data
and perform all the necessary stakeout operations without to use point
coordinates but by using original design data. The user is free to stakeout
and to have road design information at any stations.
Road design data can be created or be imported from LandXML format and the
complete design can be managed directly on the controller; it is possible to
manage more than one axis at the same time and all design data are displayed
in the plan view and cross-section view.
It is possible to work in two different ways:
Cross-sections at specific stations: in this case at any stations the
interpolated cross-section is calculated.
Cross-sections templates: one or more cross-section template can be applied
along the center line; cross-section template can be fully customized by the
user by defining the cross-section shape and also additional information as
superelevations and widenings.
Is is possible to stakeout the road design data and sideslopes at any station
and with any offset; the point to stakeout can be easily specified on the
cross-section view and your current position is displayed in two different
views: plan, cross-sections.
A useful command called `Where am I’ allow to have all design information
about your current position along the road: station, H offset, H alignment, V
alignment, Design elevation, Elevation,
eField User Guide | 2023-01
Page| 160
eField User Guide V7.5.0
elevation difference from design elevation and from current surface, Cross
slope.
A command called `Survey cross-section’ allow to measure crosssection points
at any stations.
It is possible to stakeout road design data and use a tridimensional design
model(surface) as reference for the elevations.
5.5.2 Road manager
Road manager is the control panel of all the data of the road project. They
are listed all axes that have been loaded; the road definition can be imported
from LandXML format.
It is possible to list road in two different ways:
Select: in this case you can select a road to stakeout.
Edit: when you click a road, the Delete, Edit and Property menus appear,
enabling you to delete or edit the road definition, or to edit the properties
of the road.
You can switch between Select and Edit modes via the Modify menu at the top
right.
TIP If the road is imported through a LandXML file, you can`t edit the
definition of the road, can only view it.
eField User Guide | 2023-01

eField User Guide V7.5.0
Define a road
When defining a road, you create a rodx file and add elements to complete the
road definition.
The station equations define station values for an alignment.
The horizontal alignment defines a line that runs along the center of the
road.
The vertical alignment defines the changes in the elevation of the road.
The cross-section template defines a cross section of the road at a point
across the road to define how wide it is at different points.
The cross-section template must be defined only for the right side of the
section but the definition can also be used for the left side.
Add a template for each change in width. The template may consist of any
number of strings.
Add cross-section template positions to assign the appropriate template at
different stations along the road.
Add superelevation and widening to add extra slope and widening on curves in a
road design to assist vehicles negotiating the curves.
The sideslope tempate defines the shape and the characteristics of the section
to be applied along a track; through the composition of simple linear elements
it`s also possible to define shapes of complex sections.

eField User Guide V7.5.0
Slope
Enter the Slope to define the element of the sideslope. The shape of the sideslope is relative to the left/right side axis point at a certain station. From the side axis to the direction away from the center axis, positive values represent uphill and negative values represent downhill.
Width
Enter the Width to define the element of the cross-section.
Key in the sideslope template positions
After adding sideslope templates, you can specify the station at which the
Roads software starts to apply each template. A template is applied within a
range specified by the start station and end station.
The software supports the following sideslope transition types:
No gradient: The same sideslope template is used for this range.
Gradient: A start template is applied at the start station and an end template
is applied at the end station. The values defining each element are then
interpolated linearly from the start station to the end station. The start and
end template must have the same number of elements.

Import road definition from LandXML format
LandXML road file can contain one or more alignments with associated road
definition information.
Select the LandXML file to import. All axes will be loaded and visualized in
the list.
The software can obtain the following road components from a LandXML file:
Station equations: Define station values for an alignment.
Horizontal alignment: Define a line that runs along the center of the road.
eField User Guide | 2023-01
Page| 180
eField User Guide V7.5.0
Vertical alignment: Define the changes in the elevation of the road.
Cross-section: Define how wide it is at different points across the road. The
cross-section may consist of any number of strings.
String interpolation
The cross-sections are computed by determining where the cross-section line,
formed at right angles to the alignment cuts the strings associated with the
alignment. For interpolated stations the offset and elevation values for the
position on an associated string is interpolated from the offset and elevation
values of the previous and next positions on that string. This ensures the
integrity of the design, especially on tight curves.
See the following example, where the cross section at station 100 has a string
offset from the alignment by 3 and an elevation of 25. The next cross section
at station 120 has a string offset by 5 and an elevation of 23. The position
on the string for the interpolated station 110 is interpolated as shown to
give an offset of 4 and an elevation of 24.
