When creating alignments, use a naming format that identifies the real-world reference for the alignment, such as “MapleSt - Edge_of_Pavement”. The default names such as “Alignment - 1” can get confusing as the design progresses and the number of alignments multiplies. Either type in the name of each alignment as you create it, or modify the alignment naming template to add any standard text to the name, such as project phase.
Some corridors can be designed entirely from a single centerline alignment, but most require additional alignments, such as the centerlines of intersecting roads. Create these other alignments before generating the corridor if you have the design information available. Other alignments such as gutter flow lines and curb returns, can be generated from the corridor design or added later in the process.
