Dear All, It seems to me that I am not the first person which ask about that, but searching the archive seems to me too time consuming… Could you sent me explanation or link to some mails: Can I model in Google SketchUp interior window (between two zones). Does Trnsys (TRNBuild) accept such elements? If yes – how can I do it??? Regards! ----------------------------------------- mgr inż.
