I started exporting the Pipe Fittings by the Default 'IFC4 Design Transfer View' in Revit 2019, and I have noticed all curved families are missing.
I have then went through multiple testing with v. 19.3.0.0 and below are the best outcome with the majority of elements I could get by exporting the geometry as High level of detail and ticking 'Allow use of mixed "Solid Model" representation', 'Use active view when creating geometry' and 'Keep Tasselled Geometry as Triangulation':

IFC4 export opened in Solibri Model Checker: [cid:image005.jpg@01D5A6B6.A4ECD1E0]
IFC4 model imported back into Revit 2019:
Same result as Solibri [cid:image007.jpg@01D5A6B6.A4ECD1E0]
IFC4 export opened in BIMcollab Zoom 3:
Surprisingly, some of the bends that weren't visible in Solibri or IFC import, have already appeared as curved segments and others appeared as a flat surface (circled in Red below) [cid:image009.jpg@01D5A6B6.A4ECD1E0]
IFC2x3 export opened in Solibri Model Checker:
Same settings however based on 'IFC 2x3 Coordination View 2.0' seems to fine [cid:image015.jpg@01D5A6B6.A4ECD1E0]
I have attached the Revit file I used for the export FYI.
Please let me know if there is a way to fix that in IFC4.
