Concrete elements are missing from the exported IFC file
Environment
Not environment-specific
Problem: When I export concrete elements to IFC using the selected objects option, some objects are missing from the file. There doesn't seem to be any clear logic which objects are missing.
Solution: Do not select any rebars in the model view when exporting to IFC. This way you should be able to export all the selected elements. The easiest way to ensure that no rebars are selected is to hide the Reinforcing bars from the Display settings. When you select the option Reinforcing bars on the Advanced tab of the Export to IFC dialog box, all the rebars connected to the selected father parts are exported, so there is no need to select any rebars for exporting separately.
