Hi,
I cannot see what kind of tab is open in that screenshot, but from context I am guessing it is a Section View. In that case, the visibility of Windows/Doors is not controlled by the 3D filter, but the MVO (the 3D Filter is for when you are making 3D documents of the same view).
If that is so, then I think this might be your problem:

This issue is registered in our system (as #224959), but is not yet fixed. Until we manage to fix it, it should show the outlines properly as long as you use "Core Only" instead of "Core of Load-Bearing Elements Only", and hide the non-loadbearing elements by layer. I hope this solves your issue for the time being.
