Got a minute? We appreciate your feedback:
Curved beam and arched beam is not exporting to Etabs through IFC. Y?
I have attached the image.
In this post, they have given to convert from AC to IFC through Revit software,
But if we don't have Revit, the convertion we need to do using with Archicad
Could you take the IFC exported from Archicad and open it in an IFC Viewer such as Solibri?
Can you see those elements in Solibri?
If yes, that means the IFC Export is successful, but the IFC IMport into Etabs causes the problem.
If no, then you should try exporting the IFC using other options, for example, try to export geometry as BREP which will always export exact geometries.
