I watched this tutorial and they made a bedroom floor by creating a plane and adding thickness modifier.
I don't get why they would use that instead of just extruding it up along the z-axis?
Only difference I noticed is the thickness floor only has a top face on edit mode, but extruding it creates faces on all sides.
Does it matter for creating models?
Or as long as you don't need extra faces, then thickness would make sense?
Is there a benefit for using either or?
