Thank you very much Andy !    I did not see the post from Eric. By the way, it seems not to avoid obstacles:  Here it routed over the ground pad of a board edge SMA connector. Many Thanks ! rudi

I made this particular project Public: [https://easyeda.com/luudee/usb-3-to-sma](https://easyeda.com/luudee/usb-3-to-sma) I worked around the above issue, by: 1) moving the SMA connectors inside. 2) Then routing the differential signals. 3) locking the traces. 4) Moving the SMA connectors back. 5) Adding a small trace from the SMA connector to the differential signal. It looks good now!~~~~ rudi

Thanks for your feedback.
