How do I draw a line across an alignment at a specific station and offset?
Under the Lines/Curves pull down menu select Draw line @ Station/Offset, Specify station, then specify two offsets. If you want the line equidistant across the alignment specify the same offset but as positive and negative (e.g. 20 and 20). You could draw to one side by using offsets 0 and 20, for example.
