PR: Multiple IFC types for single Revit type element

[canpolatbaris]

Problem Description

I have a single alarm type, which has 10 instances in a model. It is exported as 3 different types, with the same name and information. When I check the ifc file within Solibri or Notepad, the only different information is GUIDs for those types. The instances in the project are seperated as 1-4-5. Normally, they should all belong to the single Ifc type.

This behaviour is not version specific. I attached the model (default revit template with the 10 instances of the same type). Also, using standard 2x3 CV export or IFC4RV export, or using or not using userdefinedpropertyset file doesnt change the behaviour. test_for_ifc.zip
