So I'm sure a lot of people are going crazy trying to do some precision building, with the clipping and snapping issues, I got some tips to help with that.
When placing a wall or floor if you do not want it to snap look down at the ground more until your cursor is off the object, then you can move it closer to other objects without it snapping beside them.
Also if your having a hard time building a fence against other objects and your gaps are ending up too big use the same trick as above and their outlines will turn green even though there clipping, this lets you place them much closer to bushes and houses then you normally can and close up those nasty gaps.
Bonus tip thanks to many people in these forums, raiders will not steal power armor without fusion cores so take those cores out when your leaving suits in settlements.
Final tip everyone should already know, without any perks you get much less materials back for scrapping objects so when your working on a design try not to scrap anything till its done, just put the extra objects aside that you might need again.
Stay safe wanderers.
