Import Excellon format in KiCad

[paulvdh]

Does this look familiar:

I created it with KiCad’s gerber viewer, but before I did I first pasted the header of another drill file into your file. When opened in a text editor your drill files seem to only hold coordinates and are missing the decimal points. I also do not know if it’s metric, imperial or banana units, so the scale may be vastly off when the file assumes the header information of another drill file, but at least the data itself is present.

I guess it is a very old format, and back then it was common to omit such information. I also tried gerbv from the GEDA project, but it also chokes on your (unmodified) file.

A quite different approach is:

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…

With that you do not directly fix your drill files, but by creating a KiCad project from your Gerbers, you can replace the pads with real footprints in KiCad, and those new footprints include fresh holes too.
