What I usually do when exporting to IFC is using a 3D view where I isolate the parts to export and in the IFC exporter check the box for option Only export parts visible in view.

Actually, I tried so many times with this but somehow I wasn't able to export this.

I don't know what's going wrong again and again. And because of the versions of those softwares many senior engineers are not having much experience on that.

So, I am not having any guidance on that. Even though YouTube and online sources also don't have any clear explanations on this matter.
