This function exports a specified road layer in HEC RAS SDF file format.
Civil Designer exports the following:
A single STREAM NETWORK that ranges between the specified start and end chainages.
A single REACH that runs along the coordinated chainages.
The SDF file format is as follows:

Procedure
In order to export HEC-RAS sections you must have an alignment along which the cross-sections are extracted.
Specify the chainage range you want to export, and the road cross-section layer to export. You can also apply a constant to the chainages and elevations by checking the Add constants to sections option.
Click OK.
