Bad import of step file

[jmansion]

I generated a STEP file with cadQuery, its quite simple.

However, viewing (and subsequent re-export) in ABViewer 15 has an artifact on one of the faces which hosts a hole cut.

FreeCAD imports correctly, and the viewer I use in vscode in development gets it right too.

File attached - there is a very thin fillament across part of the hole. I've had similar artifacts from numerical precision in OpenSCAD (not exporting, just internally) but I believe teh STEP format should not be problematic.

Hi,
