Unfortunately, I'm still quite a noob in Fortnite and play only a few days ago. I was told to build my focus and build fast, but how can I install doors etc if I have a wall in front of me and go to r3 or edit and then select 2 fields and confirm with r3 just happens nothing. I can only clear my walls etc with the pickaxe. What am I doing wrong? I've been around for 40 minutes, it's just not possible.

Just EDIT…

So on PC press G and press on PlayStation ume long circle I think.

Then in the bottom row, select the middle one and the one above and then hit the bottom.
