i used Kicad well…and i upgraded Kicad5 to Kicad6.
i have some problem abont kicad6 to Altium converter.
when i used kicad5, Kicad to Altium converter is converted well.
But, when i used kicad6, kicad6 to Altium converter is strange about PCB.
PCB is not display anything. Just i can see Edge line. No trace and No device.
This is probably a problem with the KiCad file importer in Altium not being updated to accept the new V6.x.x format.
I think posting on an Altium forum would get you more help.
