There is a way to bypass some of the clipping while building in a settlement, this is very helpful especially if you are on consoles(Xbox & Playstation). As we don’t have access to the Fallout 4 console like people that play on PC.
This trick will allow all clipping to be based on the floor covering decoration of your choice. It will however doesn’t make you able to put through things your built yourself.
You can clip through most objects, but this is yet another useful settlement bug.
Step by Step
- Go under Decorations > Floor Coverings and select mat or rug
- Place it on the ground
- Place your structure,wall or whatever on the floor covering object(Mat, rug), it doesn’t have to place on top of it. It can be placed just close to it.
- Then press the select key and hold it to pick up all objects
- You should now be able to place it through objects. This however does not work if it collide with another settlement item, but you will be able to do a lot more stuff.
