With Tekla BIMsight you can combine, view and check modelled building information created with almost any modeling software. The supported file formats are DWG, DGN and IFC, which is the preferred format. Tekla Structures Viewer and Tekla BIMsight are not compatible. However, if the designers provide you the Tekla Structures models in IFC format, you are able to view them as well as check for clashes and add documents and comments with Tekla BIMsight. BR Heikki
