I am converting a set of Gerbers generated by Proteus to Kicad. I have only the Gerbers & drill file.
The gerbers imported fine. A README file indicates “CADCAM Drill TOP-BOT Plated.GBR” is the drill file.
So I re-named the file - but the drill import failed
The file starts like this -

The other thing is that when I choode “export to PCBNEW” all pads (SMD and PTH) are round and the pattern at the front is copied to the back.
