Hello,
I was trying to build something here but I don't think the structure exists yet so I'm just throwing an idea here: It would be nice to have a Sloped double door (smaller than the large one which are for dinos)

They could be used to make something like a basement or Anti-tornado / bunker entry combined with some nice stairs under them it would be so sick!

I really hope someone would implement this idea. I did not see it in any build mods I've come accross and as Nominal Structure is a fork of Structure Plus, it's one of the few mod closer to get it working (as Sloped dino gates aleady exist in S+).

I've seen some cool additions from Nominal Structures in the changelogs, so it might interests you to have this (new ?) idea as well. (I also posted this idea on the Structure Plus mod discussion, but I don't think it will ever be implemented by OrionSun looking at how he replied to my post)

Double hachframe would just be to complete the collection, but I don't think I would use it right now. Yet it's a nice idea I guess

Thanks for reading me.
