Updating pcb from schematic in 4.0.7

There is no need to re-create gerbers. The normal way is to archive a set of gerber files that is used for PCB production.
With KiCad you can also re-create a PCB file by exporting the gerbers from KiCad’s gerber viewer to a PCB project.

Reverse engineering KiCad project from Gerber files

The goal of this reverse-engineering tutorial is to re-create a complete KiCad project from partial information assuming the only information available is a schematic in some readable, (but not EDA form, such as a .pdf or a .png picture), and a set of gerber files. The Gerber files will create a PCB with much PCB information missing, however, using this method is easier than re-designing a PCB from scratch, and can also be extended to any other program that creates Gerber files. What is “resc…
