When adding points to traverses based on their point codes, you can further control which traverse points are add to through the use of Aliases.
When you specify an Alias, point are added to the point code traverse corresponding to the Alias instead of the traverse corresponding to the code.
Here is an example
Code Description Alias
SW Sidewalk
SW1 Sidewalk SW
SW2 Sidewalk SW
When these three codes are sorted into traverses, only one traverse is created for the SW code. Points with the SW1 and SW2 are also added to the SW code traverse because of their Aliases. In addition, the SW1 and SW2 codes do not create corresponding traverses since no points would be add in them.
Aliases are handy when you want to place more than one type of utility into a single ‘Utility’ traverse. Doing so allows you to easily turn utilities on or off in a drawing and export them to a utilities layer when writing a DWG file.
