While the Columbus user interface provides great flexibility and control when adjusting a network, any change to those project settings settings will affect the adjustment results. For this reason, Columbus supports the concept of adjusting from a file. The Adjust From File page allows you to perform an adjustment based solely on the contents of an input file, bypassing the user interface settings.
It’s similar to solving an adjustment from a command line prompt, but with the ability to view the results within sortable user interface grids.
To use Adjust From File, simply define your entire network adjustment settings (all adjustment parameters, data, overrides, etc.) in one data file, and then hand off that file to the adjustment engine. There is no need to change the user interface settings, because your input file tells the network adjustment engine exactly what to do. If you never change the input file, the results will always be the same, run after run. Changes in the Columbus user interface will not affect results when using the Adjust From File feature.
Projects that have been laying around for months, and whose data files have not changed, can be resolved instantly using Adjust From File, with the added assurance that the original adjustment settings are intact.
With Adjust From File, you can share data with others and be guaranteed to produce the same results each time. Once you try Adjust From File, you may never want to adjust using the main user interface again!
