IFC & Groups (Displacement of objects)

[Asemblance]

Hi All,

 

I'm trying to export an IFC model for a BIM project, and have run into some problems with grouped objects. Hopefully something I'm just not understanding properly..

 

When I view IFC data I've exported, any objects contained in a group seem to shift from their correct positions. Screenshots attached, of the same objects not grouped, then grouped (you can see how the row of 4 blue panels shift out of position). Have I missed something? Any tips??

 

 

 

 

Thanks, A
