Copy, paste & mirror

Duplicate placed-and-routed work instead of rebuilding it, within a board or across boards.

  1. Copy / paste, including across boards

    Select, copy, paste, in this board or another one. Connections re-resolve by net name, so a pasted block joins the destination’s GND, not a ghost of its old one.

  2. Mirror to the other side

    Copy & mirror or mirror-in-place flips the whole subtree. It’s a generic rewrite, verified by flipping 120 footprints twice with zero drift.

Why name resolution matters: a paste that duplicated nets would split your ground into two islands, which DRC would then flag. Resolving by name joins the pasted block to the destination board’s existing nets.
