Hi, I try to update IDF file from version 8.6 to version 9.0 but modified one has all FenestrationSurface:Detailed removed. EP 8.6 could run it successfully. Don't understand why FenestrationSurface:Detailed has been being removed without replacement objects - is it error?
thanks
The original file: 8.6.0 The updated: 9.0.1

Conversion 8.6 => 8.7 Starting new Transition.audit Will create new full IDFs Will create new IDF lines with units where applicable Will create new IDF lines leaving blank incoming fields as blank (no default fill) Processing IDF -- G:\new_export.idf

Conversion 8.7 => 8.8 Starting new Transition.audit Will create new full IDFs Will create new IDF lines with units where applicable Will create new IDF lines leaving blank incoming fields as blank (no default fill) Processing IDF -- G:\new_export.idf

.............. Many repeated Warning and all FenestrationSurface:Detailed disappeared in updated idf I could not find problems with mentioned surfaces while it could run with EP 8.6
