Road Objects

Road Objects

Road objects can be cross section based or stringline based.

Cross section based road objects:

Cross section based road objects:

Cross section based road objects consist of:

Cross section based road objects consist of:

A 3D alignment that has been created or chosen to serve as its centreline.
Cross section templates assigned to chainage values along the centreline.
Several material layers containing stringlines of the same level, material or phase of construction.

• A 3D alignment that has been created or chosen to serve as its centreline.

Any of the alignments available within the project can be chosen as centreline.

• Cross section templates assigned to chainage values along the centreline.

Cross section templates remain in the project even if assignments are deleted.

• Several material layers containing stringlines of the same level, material or phase of construction.

Daylight stringlines require a target surface to exist in the road object.

Example:

Example:

Optionally a target surface can be assigned to the road object to visualise cut or fill slopes. It must be available within the project as a surface, before it can be chosen as target surface.

Example:

Example:

If the target surface is removed from the road object, the so-called daylight stringlines which indicate the intersection of the road design with the terrain model also disappear.

Stringline based road objects:

Stringline based road objects:

Road objects imported from external files often come in in the form of a list of stringlines.

In this case the stringlines define the road object, which has typically been calculated in a 3rd party software and sent to Infinity for its preparation and conversion to a field-compatible format.

Example:

Example:

Any of the stringlines available within the road object can be set as centreline:

Any of the stringlines available within the road object can be set as centreline:

Right-click on the stringline and select Set as Centreline from the context menu.

Set as Centreline

To create a new road object:

To create a new road object:

1.	Select Road from the Infrastructure ribbon bar.Next to the Property Grid the New Road tab opens up.
2.	Enter the road properties.Go to Details and select    Edit next to Centreline to optionally select a centreline. All alignments available in the project are available for selection.Select    Edit next to Target Surface to optionally select a target surface. All surfaces available in the project are available for selection.Having a target helps when you intend to assign cross sections to the road.
3.	Select Create.

The new road object is added to the list in the navigator and the inspector.

To edit a road object:

To edit a road object:

1.	To edit a road right-click on the Road object and select    Edit from the context menu.The Infrastructure Manager opens up next to the Inspector.
2.	To assign cross section templates go to the Cross Sections tab.Each assigned cross section is added under Cross Section Assignments in the Inspector and the Navigator.
3.	Optionally add Material Layers.To add a new layer select Road Design > Material Layer in the Infrastructure ribbon bar.

Material Layer

When you assign cross sections to a stringline based road the nodes have to be assigned to material layers of their own.

Simple stringlines cannot share a material layer with stringlines resulting from cross section assignments.
