This functin allows you to coordinate the chainage points along the alignment, and produce a simple listing of the coordinates.
To run this option, an alignment defined by PI points and curve details must already exist. The start and end chainage for the calculation must be specified. The default values are calculated from the entered alignment but you are free to specify your own range.
If a road database has not been created for the current road, or if there is a database but it has no chainages, then chainage intervals must be specified for both straights and curves. Chainages at the specified interval are then inserted into the roads database, along with the calculated coordinates.
If the road database already exists, you have the option of using the road index (See the section on the road index). Each chainage record in the index has new coordinates calculated.
Make sure the Output window is open to see the listing on the screen.
