Rev2016 GetBuildingConstruction() throws InternalExceptionProxy - cannot find...

[eN27]

Why this code under Revit 2016 throws exception? On Revit 2015 everything was fine ...

Document document = cmdData.Application.ActiveUIDocument.Document;
ElementId eid     = EnergyDataSettings.GetBuildingConstructionSetElementId(document);
MEPBuildingConstruction mEPBuildingConstruction = document.GetElement(eid) as MEPBuildingConstruction;
Construction c    = mEPBuildingConstruction.GetBuildingConstruction(Autodesk.Revit.DB.Analysis.ConstructionType.Door);

Autodesk.Revit.Proxy.Exceptions.InternalExceptionProxy: cannot find creator to create the public API instance.

Dear eN27,

Thank you for your query.

Which exact line throws that exception?

Have you looked at the various elements involved in RevitLookup?

What happens there?

In order for us to say anything more at all, we will need a reproducible case to explore including an absolutely minimal external command implementation and an absolutely minimal sample model to execute it it:

I hope this helps.

Last one, method GetBuildingConstruction() from MEPBuildingConstruction class.

Please see attachment RevitSample.zip, as a minimal model you can use any empty model, based on any default Revit template (Construction Template for example), it should work always.

I'am trying get these informations:

Under Revit 2015, it works perfect.

Under Revit 2016, 16.0.428.0 20150220_1215(x64) I get:

For me, it looks like internal Revit exception ....
