I have several AECOsim v8i 3D model files. I want to convert them into IFC4. When I ran the below one with the batch process, the IFC files come with the IFC2X3 version only. I need the key-in command or settings to convert the AECOsim v8i 3D model files into IFC4 using the batch process. I have both Openbuilding designer and AECOsim v8i. Please advice.
