In ArcGIS Pro ModelBuilder, the Create Building Scene Layer Content tool does not accept the Make Building Layer or Save To Layer File tool as an input.
Creating building scene layers using layer files as input in ModelBuilder. This was re-tested in ArcGIS Pro 3.5. In this particular support case, the IFC has an unknown coordinate system. The Create Building Scene Layer Content tool fails because not coordinate system is in the feature dataset. Ensure the BIM model is correctly georeferenced with a spatial reference defined.
