You probably need to open .idf file in sketchup instead of .skp file. Thanks, Tauha From: trnsys-users-bounces@cae.wisc.edu [mailto:trnsys-users-bounces@cae.wisc.edu] On Behalf Of Stefano Lazzari Dear Forum, I am a new user of TRNSYS 17 and SketchUp 8. After creating the geometry within SketchUp (paying attention to draw always “inside” each activated zone) I saved both .skp and .idf files without getting error messages. Then, I opened the .skp file in SkethUp to proceed with the matching of adjacent surfaces. However, when I activate a zone some (many) surfaces are not recognized by the Object Info Tool (they can be selected on screen but are simply not seen by the Object Info Tool: the area showing Object Inputs properties is blank and the gray text “No EnergyPlus object selected” appears). Where I am wrong? Since the geometry is quite complicated, I hope I do not need to rebuild it from scratch… Thank you very much for your help. Regards, Stefano Lazzari Dr. Eng. Ph.D. Stefano Lazzari |
