About Annotations for Component Roads

InfraWorks displays in-canvas annotations for component roads depending on your selection and view position.

Note: Units of measurement displayed in annotations correspond to the units of measurement you specify in Application Options.

Some road annotations are editable. Refer to the table below for more information about editable road annotations. All annotations provide information to help in editing the road components. Depending on your selection and viewport position, the model will display values for:

fixed increment stations (in 50 meters or 100 feet increments)
road station/elevation at geometric end points for horizontal and vertical alignment
roadside grading area lengths
lengths of component parts and road transitions
area of easements, parcels, and right of ways
curve radius, curve length, and spiral in/out A values for horizontal curves

To hide road annotations: with the road selected, right-click and uncheckmark Show Road Geometry. Note that this option also hides the road manipulators for editing horizontal and vertical geometry. To show them again, checkmark Show Road Geometry.

Note: If annotations do not display when you check Show Road Geometry for a selected component road, you need to turn on the control, In-Canvas Labels, from the Interactions Settings menu of the high-level Visualization menu. In-Canvas Labels controls the default display (or hiding) of annotations and other labels in the current, high-level view: engineering view or conceptual view. You can set the default differently for each view.

Annotations display at different zoom levels:

Annotations for component roads will display when you select a road and zoom in. When you are zoomed out too far from the selected road, you will not see road annotations at all.

Road Annotations Hidden

However, as you zoom in to the selected road, the annotations will re-size and increase their display detail depending on how far your viewport position is from the selected road or component.

Road Annotations Visible

Horizontal Road Geometry (in Plan View)

When you are viewing a road's horizontal geometry from above, the model displays station values for horizontal geometry such as points of intersection, and points of tangency.

In plan view, fixed increment station labels also display at every 100 feet or 50 meter intervals.

Horizontal Geometry (Spiral-Curve-Spiral)

Labels for points of change to horizontal spiral-curve-spiral geometry include a non-configurable prefix. Additionally, curve radius, curve length, and A values for Spiral In and Spiral Out are shown-in canvas.

Horizontal Geometry spiral curve spiral

Note: The curve radius and A values are editable. Click on the curve radius value label or an A value label and input new values to directly modify that curve property in-canvas. You can also modify these values in the Stack.

TS = point of change from tangent to spiral curve
SC = point of change from spiral curve to circular curve
CS = point of change from circular curve to spiral curve
ST = point of change from spiral curve to tangent

Horizontal Geometry (Curve)

Labels for horizontal curve geometry include a non-configurable prefix.

Horizontal Geometry curve

BC = beginning of curve
EC = end of curve

Vertical Geometry (in Profile View)

When you orbit to view the road's vertical profile, the model displays station values and elevations for vertical profile points such as points of vertical intersection and points of tangency.

Vertical Geometry

Roadside Grading

When you select a roadside grading area for a component road, the model displays length values for the grading area you select. These values are dynamic and will update if you split or modify roadside grading areas.

Component Road Transitions

When you select a component part that has Transition In and/or Transition Out applied to it, the model displays length values for the tapered transitions, and full width sections of the component. These values are dynamic and will update if you modify the length of road transitions.

Component Road Transitions

Component Part Length

When you select an individual component part in a component road assembly, InfraWorks calculates and displays the length of that selected component. Component part label values are dynamic and will update if you split or modify a component's length.

Easements, Parcels, and Rights of Way

When you select an easement, parcel, or right of way, the model displays a value for the area of the selected easement, parcel, or right of way. These values are dynamic and will update if you modify the area of the easement, parcel, or right of way.
