Unfortunately trims and Solid Element Operations do not show in floor plan - they should be fine in 3D.
You have to 'fake it with fills and lines.
Or you can try to convert it all to a morph - that will show a more realistic plan view.
But once a morph it may be harder to edit if you need to change anything.
Try with a copy first - i.e. copy and paste the elements to duplicate them.
If the copy morph does work, maybe use that in plan but keep the original in 3D.
Use layers so you can see the morph in plan but the real model in 3D.
If you need to edit the real model, then do so and delete the morph.
Make a new duplicate and convert that yo a morph again.
