Certain Revit IFC Beams not converted to ARCHICAD Beams

Hello all.
I have a problem with REVIT IFC Beams. Some of them is Beams, another – Objects. Why? What's wrong?

Here is google translate of question:
287. WHY PART ELEMENTS Truss obtained with REVIT IFC "OBJECTS" AND REST OF THEM - "PROFILE BEAMS"?
(Working with REVIT Structure engineers. Guys performed the design of the roof, which we put in our project to fix conflicts and correct display of units. Why are some elements appear Objects, remaining Incline profiled beam? What should be done in REVIT to get all the elements were profiled inclined beams in ARCHICAD?)

Here is IFC txt screen on Object Beam:
Why this objets convert to ARCHICAD Objects after Merge IFC?
Here is original IFC REVIT Export (it is not our bureau work):

After Import REVIT IFC in ARCHICAD we have:
- 30 wrong converted Beams to ARCHICAD Objects
- 48 right Complex Profile Beams

Why?

I have checked the IFC file. Here is what is happening:
The Beams that are simple extruded profiles (they are not cut by Purlins) are converted to Extrusions in the IFC file, which can then be properly converted to ARCHICAD Beams.
The Beams that are cut by the Purlins in Revit are converted to BREP in the IFC file to preserve their exact geometry. Since these are no longer Extrusions, they cannot be converted to ARCHICAD Beams (since ARCHICAD Beams do not have such options), so they are converted to Objects to preserve the exact geometry.

The consultant should remove the cuts of those Beams by those Purlins in Revit so when you view those Beams in 3D they are simple extrusions. Then resave as IFC and then they will be converted properly to ARCHICAD Beams.
