IFC Export to Revit :: IfcPolyLine #1063146 is too short, discarding

[Anonymous]

Any idea how I can track this one down?;)

That's a Revit limitation, not ARCHICAD. It may happen when you have smaller items, which are meshed (triangulated) upon export and end up as small triangles. Anything below a certain size is discarded by Revit.

Typical situations are inside the turns of a stair or within library objects with smaller details.
