Hi, I tried to import gbxml sample from http://www.gbxml.org for checking openstudio capability but the result is still poor.There is a lot of faults. I am also not able to export shading element data from OS to gbXML file (check the data in xml file) - how to export and validate gbxml file with complex construction elements ? Should i use lastest version of TRANE Trace to get all gbxml import capabilities ? The lastest material from trane trace website was issued 5 years ago. Thank
