The current nightly (5.99.0-7040-g8c08b861ab) produces an empty board (board body only) when exporting STEP. Can anybody confirm this?
Working fine on today’s version and last Fridays’s version too.

I just exported a step file with KiCad:
Version: 5.99.0-unknown-fa8c48675~104~ubuntu20.04.1, release build
In FreeCAD it looks like an empty PCB with no tracks:
Which was sort of expected, because the export of the step file generated lots of errors:

Step file /home/paul/projects/kicad/mumar_base_stm32_5.99/mumar_base_stm32.step created
STEP file:
/home/paul/projects/kicad/mumar_base_stm32_5.99/mumar_base_stm32.step
has been created successfully.
But the simplest step is to simply open the PCB in KiCad’s internal 3D viewer. That also does not show any 3D models.
This PCB was first designed in KiCad V5, then opened and saved with KiCad V5.99 and the links to 3D got broken.
I have not looked into details yet.
=================
A bit later.
I changed:
"… / Preferences / Configure Paths / KISYS3DMOD"
from:
/usr/lib/kicad-nightly/share/kicad/3dmodels/
to:
/usr/share/kicad/modules/packages3d
And now all 2D models in both KiCad’s 3D viewer and in the exported STEP file are back.
@paulvdh: In the 3D viewer, the board is ok, no missing 3D models.
@pedro: I see you have OCE on. The official CMakeSettings.json has OCC on, OCE off. Maybe that’s a point, I’ll check that. I’m new to building, maybe I don’t have my ducks in a row 
But anyways, it happens with the official nightly.
Hi Pedro @pedro
It is the same with the official W10 build and my own compile.
Some boards work, others don’t. I think I’ll cry for help in the dev’s mailing list.
I can’t confirm. Just exported a demo project to report this bug:
Obviously it’s a bug. The file format changed in today’s nightly (I cannot step back to yesterday’s board version). Yesterday’s board version worked even today, after saving (converting) it with today’s nightly the bug appeared. Report already filed.
