Hi Brad, When you export from Tekla Structrures, use export to IFC. From IFC export dialog click edit for additional property sets. Then select the wanted properties and save list of selected properties to a name. Then verify on export dialog that you have that name listed on the additional property sets. by exporting with these settings you should get the part position visible in Tekla BIMsight also. Best regards, Marko Myllymaa
