Kicad import leads to incorrect trace widths of net classes

[and3rson]

Hello,

First of all - thank you for this amazing piece of software!

My problem is that every time I import my kicad project into diptrace, the wire widths of net classes seem to be using incorrect units.

Source file (`main.kicad_pro`):

Code: Select all

// ...
  "net_settings": {
    "classes": [
      {
        "bus_width": 12.0,
        "clearance": 0.2,
        "diff_pair_gap": 0.25,
        "diff_pair_via_gap": 0.25,
        "diff_pair_width": 0.2,
        "line_style": 0,
        "microvia_diameter": 0.3,
        "microvia_drill": 0.1,
        "name": "Default",
        "pcb_color": "rgba(0, 0, 0, 0.000)",
        "schematic_color": "rgba(0, 0, 0, 0.000)",
        "track_width": 0.25,
        "via_diameter": 0.8,
        "via_drill": 0.4,
        "wire_width": 7.874015748031496 <<<<<<<<<<<=============
      },
// ...

`wire_width` is set to ~7.8740 (seems like it's in `mil`), an in UI it's being shown as `0.25 mm`.

However, when I import this project into diptrace, the width becomes `7.8740 mm`, so this seems like a problem with diptrace's importing feature.

Any thoughts on why is this happening or whether this can easily be fixed on my end? I've tried changing units in "View -> Units" with no luck. My only workaround for now is to manually fix wire widths of net classes every time I re-import.

Thanks in advance!

Thank you for the report. Could you please share Kicad file for verification.

Thank you for the report. Could you please share Kicad file for verification.

Sure, here it is: https://github.com/and3rson/65ad02/tree/main/kicad

I've updated my Kicad to 7.0 and the issue is still there (except that now the width is displayed as 7 mm), so I think it might be related to DipTrace's importer.

Code: Select all

  "net_settings": {
    "classes": [
      {
        "bus_width": 12,
        "clearance": 0.2,
        // ...
        "track_width": 0.25,
        "via_diameter": 0.8,
        "via_drill": 0.4,
        "wire_width": 7 <<<<<<<<==========
      },

FYI - My DipTrace version is 4.3.0.4.
