Exporting round cut outs to a IFC model

Hello again

After exporting our model to an IFC file and open it i.e. on Revit software all round cut outs and circle openings on walls and slabs are shown as a polygonal cut outs and openings.

Our question is if there is a way to solve this problem or if this is normal when opening the file on a different software as Revit.

We had the same problem on Microstation V8i exporting dgn files to dwg files and opening them on Autocad all circles become polygonal objects

Thank you in advance for any help
