Hello,
The following Error is issued if I try to load the file “goboard-main.kicad_pcb” with the StepUp workbench in FreeCAD:

Trouble with nesting of brackets
The project can be found here: https://github.com/BerndGottschlag/goboard
The issue is present in all commits I tested. The newest commit at the time of writing is a253129a.
A few things to note:
- KiCad does not show any errors when opening the PCB and I can see the PCB in the 3D viewer.
- The PCB is currently a work-in-progress. Many footprint assignments and traces are still missing.
- Only the main board (hardware/main) has this problem, the numpad (hardware/numpad) can be loaded in FreeCAD.
- The only 3D-model I added (the USB-C jack) does not seem to be the cause of the problem. When I add it to the numpad the problem does not occur.
- If I remove all footprints from the PCB that are not from the standard library and not present on the numpad the problem still occurs.
This topic is linked to my problem:
Is there any way I can further troubleshoot the problem (e.g. logfiles)?
Do you have an Idea how to fix this?
Any help is appreciated!
