Hi Sam, In addition to models, Tekla BIMsight project .tbp package contains also all other project information such as saved views, conflict check results and added notes and documents. Since these cannot be imported to another Tekla BIMsight project as such, it would be confusing if relinking a .tbp package would bring only model files inside the TBP package to Tekla BIMsight. In version 1.6 we introduced a new refreshing functionality which can be used to add multiple model at once to a Tekla BIMsight project. See the videos and instructions starting at the following page to see how it can be utilized http://www.teklabimsight.com/helpcenter/helpTopic.jsp?topic=bim_setting_default_model_folder Hope you'll find this functioanlity useful. Thanks, Heikki
