**Feature Request** Brief title for your desired feature: An attribute which prevents the auto-router from deleting tracks before it starts How would you like the feature to work? Among other attributes of a track, a new attribute, possibly named "Locked" or "Sticky" could be added, which if set to "ON", would prevent the autorouter from deleting the track before it starts. This attribute's function could be combined with the "Lock objects" feature request: https://easyeda.com/forum/topic/Lock_component_location_on_PCB-BtnFXR9rI Why is this feature important to you? Many times, it is important that some tracks go a specific way and they must be manually drawn. Then, for the rest of the routes where it doesn't matter where they go, the autorouter can continue. The autorouter must not modify tracks which are locked like this.

In the Autorouter there is already the **Skip Nets** feature: ![enter image description here][1] Does that not do what you require? [1]: /editor/20171024/59ee3df63dace.png

"Skip nets" kind of does the opposite: it is a list of nets which autoruter will not route, but will remove. But in any case, doing this for nets is not enough. This should be a track-based operation.

Hmmmm, Maybe I have misunderstood how `Skip Nets` is supposed to work... `But in any case, doing this for nets is not enough. This should be a track-based operation.` But surely a track is a continuous piece of copper and therefore it should have the same netname all along it?

on the left side, there is a option `Remove Existing Tracks`,is that you want? and the lock feature we will provide this, but need some time.

Hi, When "Remove existing track" is turned on, then ALL tracks, those created manually and those created with autorouter will be removed before autorouter runs. If it is turned off, than ALL tracks will remain. I am suggesting that those tracks marked as "locked" (usually they will be created manually) ARE NOT removed before the autorouter runs, and other tracks (usually they will be created by the autorouter) ARE REMOVED before the autorouter runs. In this way, tracks which need special placement which is done manually will not be deleted by the autorouter.

I had thought that the `Skip Nets` list was there to make the Autorouter ignore (in other words not rip up) and tracks that were already routed. That is not what it appears to do. In fact I don't think I now understand what this feature is for.
