In an equally spread offset, which part of a layout will NOT be the same for all three lines?

In an equally spread offset, the starting point represents the location from which measurements begin. This starting point can vary depending on specific factors such as the layout of the piping system, the height of the installation, and other design considerations. Therefore, while the run, set, and travel may be consistent across the three lines in the layout, the starting point can differ significantly based on the orientation and specification of the pipes being installed. The purpose of an equally spread offset is to maintain uniformity in dimensions and angles, but each pipe's initiation point may be influenced by surrounding equipment or structural constraints, making it the correct aspect that will not remain uniform across the layout.
