      That is usually an indication that somehow the window that you
    added did not get assigned to a zone. I'd recommend that you delete
    the windows, make sure you select a zone, then start readding them a
    few at a time and importing them into TRNBuild to make sure that
    they're getting assigned correctly. It may well be that these are
    the exact steps that you are following; I have certainly seen
    Trnsys3d get into trouble assigning fenestrations to zones all of
    its own accord but I think that deleting them and then importing and
    saving lots of copies of the *.idf along the way solved my problem
    in the end.<br>
    Kind regards,<br>
