Snap Points for Structures

Hey there,

is there any kind of tutorial for Snap Point Logic, or how to configure your selfmade structures so they snap into the right place?

All I’ve seen so far are some snippets of thoughts about how this whole snapping stuff could work and this reference list, but I still don’t know what to do if I want to configure my own structures.
Are there any tutorials? I’ve searched the forum but couldn’t find something adequate.
And if not, why? I think this part is pretty important to get right, because the finest 3D models are useless if they can’t be placed in the game where the player wants them to.

I don’t think that it would be to hard to understand, but it needs to be explained from someone who knows how it really works. May a dev could take a couple of minutes to explain something?

Best regards.
