Net guides

A guide is a drawn path assigned to a net. Copper routed with Guides snap follows it, and the link persists so you can reshape the route later.

  1. Draw and assign

    In Draw, sketch the path; assign the net.

  2. Route along it

    Route that net with Guides snap on, it follows your shape instead of the router’s shortest idea.

  3. Change your mind later

    Reshape the guide and the copper reflows. Lock pins copper exactly; Detach cuts the link; deleting a guide keeps its copper.

Once copper exists, most tools keep only the geometry. A guide also keeps the intended path, which is what makes later reshaping possible.
Limit: today’s guides steer single nets. Corridor, via-stitch and length-match guide kinds share the substrate but aren’t built yet. (Length tuning itself, the meanders added to a drawn trace, is built; see differential pairs & length tuning.)
