You can modify the layout of wires by moving their vertices using Location grips. This can be helpful when you want to clean up the layout by moving the wires around walls, equipment, or other floor plan geometry.
To maintain the connectivity of a circuit, wires are anchored to devices. As a result, you cannot move the wires using the grips at their endpoints. Instead, when you move a device, the connected wires stretch accordingly.
