Hi guys

I am looking for a no build collision mod. So basically when you trying to seal some hole or anything, you will find out that outer border of the item is red instead of green. I would like to know if there is some kind of mod out there that eliminates such restriction from the game completely.

Its pain in the butt to have properly placed items without them "floating" in air because ground is eneven.

If you mean you don't want walls to float in the air because ground is uneven. Not possible, you'd be talking about a rotaion system thats way too complicated. If you meant you don't want to see the holes, slap a smaller thing in front, I use gard rails mostly.

So start at highest point and work your way down, then see where you can put a wall closer to ground and so on and so forth and refill glass and or ligth something up.

Most mods at this point are going to be a bit limited to what they can do. Until the geck is released then you will most likely find a mod that will be able to do what you want. Be a while yet before that will happen though
