On the PCB Design toolbar, click Rework > Meander .
Zoom in to see and select one of the traces in the pair.
Click along the trace in the approximate location to start the meander pattern. You should see that both traces are highlighted, and the meander curves begin. A pop-up label shows the length of the longest trace of the pair, and the percentage length of each trace. Move the cursor across the traces, to change the shape and length of the meander curves.
Move the cursor along the traces until the trace lengths are close to 100%, and the meander stops lengthening.
To save the meander, click one of the traces beyond the highlighted section.
To delete the meander and redo it, click Undo.
