1.0 Creating a Job File – Subject Network
This document will illustrate how to create, modify and customize a single line diagram using Design
Base graphical user interface. The system shown in Figure 1 will be used as an example. As the actual
step by step process is explained, the user will be simultaneously introduced to a critical application
called the “Master File Editor”. This tool allows the user to control base-parameters and settings that are
critical during the modeling and analytical process of the job file.
