Hi, I wanted to share this trick that you will definitively need if you're a base builder. It's about the requirement that a base's entrance must be "2x2", and the way to check that is to ensure that two players must be able to fit in your base entrance side/side and infront/behind.
However, if there's no second person available to check it for you, you can simply use this prop called " furniture_desk01a.mdl " It's width is about exactly the same minimum size of a 2x2 base entrance!
I hope this guide will come to use for someone!
