Hi Larry, The problem is either in the IFC exporter of Tekla Structures or in the IFC import plugin of Tekla BIMsight. Please try first to export your Tekla Structures model to IFC by using the Presentation view as an Export type to see if it’s making any difference. With that option the geometry of objects should be more accurately exported to IFC format. If that doesn't solve the issue I'll need the Tekla Structures model in order to investigate the issue further. I sent you email about this. Thanks, Heikki
