Hi Klaus Thanks for this. We hit this relocation of BSa's XSD earlier in the year (#273) in relation to some tests... I think the latest xbim v5.1 code handles...

Looks to be triggering a StackoverflowException

Confirmed still an issue in 5.1.254.0.26 Geometry. No warnings generated It looks like the geometry is there but obscured by a bounding bx

Presumably due to: ``` GeomScene: #108903="IfcBooleanClippingResult" ["Is an empty shape"] ```

Still an issue in 5.1.346. It processes gracefully but with an error logged: ``` Processing failure General Error Creating IfcExtrudedAreaSolid, #9774 at Xbim.Geometry.XbimGeometryCreator.Create(IIfcGeometricRepresentationItem geomRep, IIfcAxis2Placement3D objectLocation, ILogger logger) at Xbim.Geometry.Engine.Interop.XbimGeometryEngine.Create(IIfcGeometricRepresentationItem...

I'm not familiar with running under Wine. The issue here doesn't look like geometry - looks like you're missing the .netcore runtime/SDK. Assuming you get Essentials running then I guess...

OK: so you understand. The reason for this is because Xbim.Geometry.EngineXX.dll is not a managed assembly, so the .net compiler doesn't automatically treat it as a transitive dependency and copy...

Tested in v4 where it fails gracefully with an error:  In the very latest v5.1.307 geometry `CreateContext` hangs with the only warning being: ``` Xbim.ModelGeometry.Scene.Xbim3DModelContext GeomEngine: #351="IfcCompositeCurveSegment" ["Unconnected composite...

Martin & I discussed this a few days ago. I guess some of it kind of depends on : 1. whether ifc4x2 introduces breaking change on ifc4x1 schema (I think...

Can you retest with the latest Geometry Engine (5.1.376)?
