Revit curtain walls and IFC export?

[jzee.101345]

Hi,

Has anybody successful expirience of exporting Revit curtain walls to ADT using IFC format. Everethigs looks good exept the curtain walls - they are missing, instead only 1 segment with 1 mm long and 7500 mm height and 0,0 coordinate.
Any suggestions with this issue?

I am using Revit and AutoCAD Arch 2010 and was able to export using 2x3 ifc without any problems.

Did you make sure to check curtain wall under options in the Import IFC dialog box in AutoCAD Arch?

All that I have founded out till now is that it is defenetly an issue of ADT. ADT 2009 64 bit doesn't translate curtain walls, ADT 2009 32 bit does it correctly with simple model, but when I try to import a model I am currently working on it just crushes in the middle of a process.
ADT 2010 64 bit translates curtain walls correctly but I still need them in 2009 version.
In addition some basic walls are missing inspite of version being used.
