After the conversion, it said that some elements could not be exported due to missing geometry.<BR /> I check the IFC ID, the elements include some columns and some walls.<BR /> <BR /> Then, I open the IFC format in ArcGIS, it shows that the elements are really missing.<BR /> <BR /> Could someone give me some suggestions?
