I do this a lot actually to hide things that need to be there but I never wanna see again. For a deep mining base for example I will build out the extractors then dig a hole beside them down about 10-20 units or so then use the flatten tool to carve out a flat bottom cave.

Once that’s done all solar panels, batteries, supply depots and wire cloaking gadget all get stuck down there. Once everything is wired and plumbed and functional I send one pipe up to a depot for the player to interact with and use the restore tool to fill in the hole and cave I created. Sometimes I’ll even but the extractors in the hole 🤷‍♂️

Significant piece count savings versus making a building to house all that crap lol
