Label Profile On Centerline

This command labels a road profile on a centerline in the plan view. First you are asked to select a road profile and a centerline. Then on the Label Profile On Centerline Settings dialog, you need to choose which labels to draw. The left list shows the available labels to draw, the right list shows the label that have been chosen to draw. Add button moves the highlighted label on the left list to the right list, Remove button moves the highlighted label on the right list to the left list, and Setup button allows you to edit the options of how to display the highlighted label in the plan view.

The available labels include:
PVC, PVI, PVT, High and Low Points: To label the station and/or elevation of the profile at these points.
Slope: To label each different slope in the profile.
Station At Interval: To label the stations along the centerline at a station interval.
Elevation At Interval: To label the profile elevations at a station interval.

On the point label edit dialog, you may choose to display either the station or elevation, or both, or neither of them, and specify their prefix or suffix. If you choose to label both the station and the elevation, the labels are drawn in two lines by default, unless you elect the option to Label Station and Elevation on Same Line. When the screen is twisted, some of the labels would possibly be drawn upside down, the Flip Texts for Twist Screen option flips the text to the proper direction. Draw with Symbol setting draws a symbol at the position of the label. Next, you would select from a list the Symbol Name, Layer Name, Style Name and Color for displaying the label. The Label Position can be set to Above or Below the centerline or to the Left or Right of the centerline. There are three Label Orientation settings: Horizontal, Parallel and Perpendicular. Text Size Scaler and Symbol Size Scaler determine the size of the text label and symbol label respectively in plan view.

The slope label edit dialog is very similar to the point label edit dialog, the big difference is the Arrow Direction. There are four arrow directions: Centerline Direction, Uphill Slope Direction, Downhill Slope Direction and Away from PVI.

An example dialog for editing Slope Label

Here's a site design example shown below, where a profile is labeled on the centerline. The PVI labels are above and parallel to the centerline, the PVC and PVT labels are below and perpendicular to the centerline, and the slopes are above and perpendicular to the centerline, their arrows are in the downhill slope direction.

A closer look of profile labels

If the road profile is modified by a Carlson program, the profile labels will be updated automatically. When you double-click on one of the labels, a dialog of the labeled PVI section will pop up for editing. In the sample dialog show below, you can modify the station, elevation, and other parameters of the PVI point. Pick button allows you to pick on the screen to get the station. Through Pt button opens a dialog where you can define a point on the profile to pass through the fixed station and elevation. When click on Spreadsheet Editor button, the road profile editor is opened for you to edit road profile.
