How to reproduce

I exported an assembly from Onshape as a .step and a .3mf. When viewed in https://3dviewer.net/ both models load correctly, but when loaded into OrcaSlicer the .3mf shows all the components in the wrong positions.

Base.zip

Here is what Base.3mf looks like in OrcaSlicer. Note also the names of the components aren't accurate:

Here is the same file loaded at 3dviewer.net:

And here is Base.step loaded into OrcaSlicer:

Actual results

Assembly is loaded with components in the wrong locations

Expected results

Model loaded cleanly
