Wiring harnesses are essential components of aircraft electrical systems, connecting and transmitting power, signals, and data. Using CAD for wiring harness design improves design efficiency, enables precise geometric modeling, and facilitates digital document management.

[0003] While CAD has achieved significant success in the drawing of aviation wiring harnesses, significantly increasing the efficiency and accuracy of their design, the traditional process for aviation manufacturing, particularly during wiring harness layout, involves drawing the wiring harness drawings using CAD, printing them using a specialized printer, laying them out on a workbench, and then laying the harness. This process presents several pain points: 1. Aviation drawings are extremely large, ranging from several meters to dozens of meters in length; 2. Modifications are cumbersome, requiring reprints if errors are made; 3. Drawings are easily damaged, requiring workers to use welding tools, which can easily ignite paper drawings; and 4. Wire tracing is difficult, requiring workers to look up the required wiring harness from a paper wiring diagram and then find the corresponding terminal numbers on the drawing, a tedious process. Therefore, it is necessary to digitally transform the entire process, achieving a digital, 1:1 display of drawings to reduce drawing preparation time and enabling wire harness highlighting to improve wiring efficiency and accuracy.
