altium2kicad creates invalid .kicad_pcb file

[BreakingSiam]

After running altium2kicad on a large Altium project, it creates a .kicad_pcb file which Kicad version "6.0.4-6f826c9f35116ubuntu18.04.1, release build" reports "does not appear to be a valid KiCad project file".

The generated .kicad_pcb file is 13891785 bytes long, and on visual inspection of the beginning of the file appears to be a valid KiCad project file.

During conversion of the altium project, after displaying writing to "Regions6/Data.dat.txt", altium2kicad reported:

The complete conversion output is attached.

Please provide me with your altium file, so that I can analyze the problem. I couldn't reach you through email.

I just tried the new Altium Importer that has been integrated into Kicad itself (one in PcbNew and on in EESchema, to be found in "File -> Import -> Non-KiCad Files", and the results are much better than altium2kicad, so I would suggest to you use the KiCad integrated importer yourself instead of altium2kicad. If it works for you, please close this issue. If it doesn't work for you, please let me know.

Has the integrated imprter in KiCAD superseded this project?

[thesourcerer8]

Yes, it was developed based on this converter, and it seems to have surpassed the quality of this converter now. So unless anyone still needs this converter, I would declare it superseded now.
