Autodesk Forge modern conversion method IFC 2x3 creates model twice
I have a IFC 2x3 format model, that I want to render using Autodesk Forge viewer. When I switched from "legacy" (Navisworks) to "modern" (Revit) conversion, the model needs a long time to finish loading in the viewer and it is rendered twice. Here is a screenshot, how it looks now:
When the model is converted using legacy conversion method, the model is rendered correctly as one. Also, other IFC viewers render the model correctly:
Is there an issue with modern conversion method and IFC 2x3 files? Other 2x3 IFC models are rendered correctly, but as stated in this stackoverflow post, I have issues with another 2x3 IFC file which may be related.
On the supported formats website, there is only stated, that IFC is supported, but not which exact versions.
Thanks for any kind of help!
As in the other post, the problem seems to be the IfcSite. After replacing longitude, latitude and elevation with '$', the model is rendered nicely. The modern conversion seems to have issues with the geographic reference point of IfcSite, altough it is only given for informational purposes (Link).
