Actually the pieces snap a lot better than in ark. Look up building tutorials on Youtube, i think it will clear a lot up for you. The game could use a few more parts, but the building system feels better than ark.

There are a few tricky parts when building a part close to the ground, but the video tutorials show a lot of good ideas on that.


If you really like to build much and have the option to use mods then maybe take a look at the building-mods. There is a mod that greatly increases the controls when building. You can then place items very fine tuned and even rotated back/forth.
