In GASMOD Version 7.0, the pipeline model may be created graphically using a drag and drop approach. In this method, objects such as pipe segments, valves, tanks, compressor stations and other devices may be selected from a toolbox and dropped on a drawing canvas. These objects can be connected with pipe segments to form the pipeline system. The properties of each object may be defined by double-clicking on them and entering data in the screen that is displayed. A video tutorial is available that explains how the pipeline model can be created graphically.
