Survey Cross Section
To perform the survey of the cross section:
- Select between Road, H Align and None as required.
- Enter the name of the Road / Horizontal alignment manually or select it from the list
.
- When no alignment is selected (None), enter the Centerline Code from the drop-down list. Click the Code button to set attributes. More...
The centerline code must be a valid line code to apply to the surveyed points for creating the alignment.
If the road has not been set, define the plane. On the first station, the survey is performed so that every next point has a different code, for example A, B, C, cl, D, E, F. Press
to automatically change the station number. The application suggests that the survey on the next station uses the same codes in the opposite order: F, E, D, cl, C, B, A. The line is created along the points with the cl code.
- Set the X-Sect Sta where the cross section will be surveyed. You can select any road point as the current point. To do it, click
in this field and select any road point in the Road Points dialog.
- Enter the Interval of distance towards the next station.
- Select the Use automatic X-Section Station check box to automatically set a next nearest cross-section station to survey.
- Select the Use Horizontal Transition Points check box to include transition points, in spite of the station distance.
- If required, click the Range Limits button to open the Survey Cross Section Limits dialog and set up monitoring of acceptable limit of distance offset between cross section measurements and right and left ranges for the current cross-section measurement. This functionality is available for cross-section survey of existing road or horizontal alignment.
- Click
to start measurements.
Optionally, you can open the Roads dialog to edit the road. To do this, select the option Edit Roads from the pop-up menu that displays by clicking
