The Power of Global Editing

Global editing is a powerful feature that has existed in all AFT software since version 1.0. The Global Editing windows for pipes and junctions allow engineers to input or modify data for all or a select group of pipes and junctions in a model. This saves countless time when there are many modeling changes that need to be made.  Rather than making changes one by one, changes can be made once and applied to an unlimited number of pipes or junctions.

The global editing feature works the same on AFT Fathom, AFT Arrow, AFT Impulse and AFT xStream. This article will focus on how global editing works in AFT Fathom. 

Here is how global editing is used. First, you must have a model. Consider the model below which is one of the Example models provided with AFT Fathom. This model is a spray system with eight spray discharge junctions. Follow each of the remaining screen images to complete the process. Global editing will be used here to change the size of each spray junction from 0.5 sq. inches (3.2 sq. cm) to 0.75 sq. in (4.8 sq. cm) in order to provide more flow for the process.

Step 7. Select the OK button at the bottom to finalize the changes. Users have the option to select the Cancel button and no changes will be made.

 

These steps can be used for any type of relevant junction as well as pipes. Use global editing with caution as you can wipe out valid data very quickly.
