Archicad --> Revit Door Swings

[LFBIMMAN]

Hi All, 

Currently send our models over to Revit users using IFC or RVT saves from the Archicad model, we have noticed that door swings do not really transfer through to Revit... well they kind of do when you move around the model in plan view in Revit they can be seen but when you let go of the middle mouse wheel they disappear.... hard to explain. 

This is how they currently look in a Revit model, we have tried using a variety of ways of importing the data but always comes out the same, does anyone know how to make them show permanently? we want to avoid linking a dwg of just door swings if possible. 

Thanks
