although, they'll hit their system limits a lot quicker than many PC players. This trick can even let console players build forever. People that do a lot of scrapping on the ground could find they never hit the object limit. It seems dropping an item doesn't increase the size count, but scrapping it will decrease the count. You can drop guns on the ground and scrap them to reduce your object count. It's unclear how things are weighted exactly right now, but as long as you don't build so much that you bring your system down, it doesn't matter too much.

It takes a lot more triangles to build a round section than a square section, so those round parts will make you hit the object limit faster. Also the 'count' isn't a one for one thing, some objects count more than others and this seems to be based on the number of triangles involved in the object mesh. Some settlements have much higher object limits than others, so where you build matters. People that start by scrapping everything will be able to build a lot more than those to scrap only what they need. All the pre-existing objects, even trees and tires, count against the size limit. Notice that size bars don't start at empty. I think the reason why some people hit the object limit more than others comes down to scrapping, where you build, and what you build.
