[ Bug ? ] Window w/ Louver Do not Export Louvre

Post by paullee »

Hi, continue testing IFC export functions with the Villa Savoye model.

Have below findings:-
  1. Have created a numbers of Windows w/ louvers
  2. The transparency of the glass panes some time becomes opaque
  3. So created a few Window objects w/o louvers and create another series of Window Objects w/ Louvers only
  4. So far still good in FC
  5. When, export to IFC and viewed in BIMserver, the louver seems disappear for the Window integrated w/ Louver
Model + IFC at :-

More findings :-
  1. Whilst the concerned Window has the integrated Louver disappeared... when viewed from outside
  2. When viewed from Inside, the Louvers are shown
  3. BIMserver / BIMsurfer problem ? Exported w/ face normal inverted ?
  4. ...Other problems to be reported in BIMserver rather than here?
  5. And when viewed in IFC++, the integrated Louvers are shown whether from Outside or Inside...

Louvers are shown in BIMserver when viewed from Inside (not from Outside)

Then clearly a bimsurfer problem... But normals are not exported in IFC. So not sure what the problem would be... Maybe something to do with transparency...
