Hi Marco, Tekla BIMsight does not make any changes to IFC models. You can change the presentation how the model is shown to you and that you can save to views. Please see help here: http://helpcenter.teklabimsight.com/helpcenter/helpTopic.jsp?topic=bim_saved_views Check the links on the right to see help on details of views. Best regards, Marko Myllymaa
