There are often gullies along a kerb channel line. However, when surveying the channel line, the number of gullies is usually not enough to accurately reflect the shape of the channel line. A combination of a line feature and the ability to plot a symbol when it is necessary is required.
The Line property page should be set to display whichever line style is required.
The Symbol property page should be set to display the symbol required for a gulley. Since the symbol is not required at every point, the symbol type should be set to a 1-point request symbol. When needed, the symbol is generated using the same method as that for a 1-point aligned symbol. The request is made by assigning the symbol request comma code, normally S, to the point on the channel line.
