I'm completely new to Blender and wanted to gain some experience with the software. As my first project I decided to recreate an entrance to a underpass that's close to where I live.
The walls from the structure are mostly continuous so I'm not sure on how (or if) should I break them into multiple objects. I tried leaving it as a single giant object but I don't know if it would give problems when adding modifiers (as I'm looking forward to round the wall edges a bit).
I also thought about breaking it down it like so:
But it still feels like the objects are too big, and since everything is a single scenario I don't know if it's really a good idea to break it down to multiple pieces. What should I do, and if there's no concrete answer, what are the pros and cons of each method?
