# Warnings after real-PCB transfer

Warnings after transferring a circuit to real-PCB may appear if:

- you move a 3D part, indicating a broken connection between the part and tracks.
- you delete a connection in 2D, indicating the tracks on the PCB no longer match the circuit.
- real-PCB was unable to route all connections, indicating the tracks do not represent the complete circuit. Unrouted connections are shown on the surface of the board.
- you use the manual transfer option and make changes to the electrical connectivity of the circuit. To fix this error, make the same change to your circuit in Crocodile Technology and then transfer the circuit again to fix the tracks. (Changes to part placement and track paths in real-PCB do not affect the electrical connectivity of the circuit and so will not produce this error.)
