3D Structure

For this topic, the first thing that came to my mind is to make a bridge because the bridge is the one
can hold and support many many different things, and it connects two different places
together. Although I find a hard time using the boolean difference tool, for some reason it looks like
some parts that are not intersected got cut too, so many ideas I was going to include in this project
got deleted from my mind.
