Error converting IFC file to WeXBim: item with the same key has already been added #30

Open MarcoGiorgi opened 6 years ago

MarcoGiorgi commented 6 years ago

I'm trying to convert an IFC file produced by Revit. I'm using the example code taken from the website. I get the following parser error:

[ArgumentException: An item with the same key has already been added.]
   System.ThrowHelper.ThrowArgumentException(ExceptionResource resource) +52

Inspecting the exception in the source, I found it's raised at line 196 of Xbim.IO/Step21/XbimP21Parser.cs: p21.Entity = EntityCreate(entityTypeName, p21.EntityLabel, InHeader, out reqProps);

The IFC file is correctly open by other IFC viewer. Is there a way to solve this issue? As I'm new to xBIM, please just give a direction on how to solve it, and I'll do my tries.

the IFC file can be found here: http://www.brainsengineering.com/bim/mep2.zip Thanks!
