Hi

I can't find the class "ExporterIFCUtils" under the IFC namespace. What references are you using ?

[recepagah12]

As reference in visual strudio, use the  using Autodesk.Revit.DB.IFC;

In IFC Namespace -->

ExporterIFCUtils -->

ComputeAreaOfCurveLoops (Ilist<CurveLoop) curveLoops)

The method return 0 for curveloops that are non-planar.

Any idea how to compute the area of the curveloops laid on the curved surfaces? I'm trying to find  the area of an opening in a curved wall.
