Hi Anders, Please check the list of installed programs. Do you see import plugins there, they should start with either "Tekla Model Sharing Foundation" or "Trimble Solutions ImportSDK". There should be import plugins for IFC, DWG, SKP and other model formats. If you don't see import plugins: Has Tekla BIMsight been installed on your computer (same one) earlier by somebody else? Best regards, Marko Myllymaa
