(1) Report node when the network is loaded, not found

　　a. The components in the schematic diagram use the package that is not available in the PCB library;

　　b. The components in the schematic diagram use the name of the name in the PCB library inconsistently packaging;

　　c. The components in the schematic diagram use the PIN Number in the PCB library inconsistent packaging. For example, the triode: Pin Number in SCH is E, B, C, and PCB is 1, 2, 3.

　　(2) You can never print it on a page when printing

　　a. No at the original point when creating the PCB library;

　　b. Move and rotate components multiple times, and there are hidden characters outside the PCB board. Select all hidden characters, reduce PCB, and then move the character to the boundary.

　　(3) The DRC report network is divided into several parts:

　　It means that this network is not connected, read the report file, and select the Connected Copper to find.

　　If it is more complicated, try not to use automatic wiring.
