I found the editable project: LCA Magnetic Plug at liquidrick/lca-magnetic-plug.
I still can’t modify it from this chat because the active project context is still the old PCBWay 4 Layer Stackup reference project. Please open LCA Magnetic Plug and start Copilot there with: “Continue the Smart PDU port card design from the previous chat.” Once I’m operating inside that project context, I can create the project files, build the schematic, size the board, place/route it, run ERC/DRC, and then export manufacturing files.
