I have and still working on something similar based on "No Mans Sky" stuff, and the best way that I have found is to get it as close as possible (by eye)
/ enable manual position, then change your Move / Rotation precision down to the lowest 0.01. (Rotation my not be needed) apart from this I'm not too sure if there is anything else apart from keep trying.
This for me seems the best way forward
Have you tried to stop and re-start the server?
I built something similar last Christmas and asked Red the same sort of question and Red replied that when electricity is implanted making timed switches will be possible, but of course this part of the game may be a while off.
Stunning 
Maybe that how Islands are being created!! 
Hello Red51 / community not sure if I have missed this anywhere or if its even been asked for but just for a QoL action that I personally would like is the ability to rotate elements using a combination of k/b + the mouse wheel, i.e. L/Shift + Mouse wheel up = Rotate clockwise / Mouse Wheel down = Rotate Anti-clockwise, this in my opinion would make when doing curves a lot faster & easier instead of having to press a key each time to rotate it.
You can also in the game settings / miscellaneous, change to "Instance digging".
Hope you have fun.
NB: just seen AlphaGodith's reply that says the same thing so you can bypass my comment lol.
Still hope you are enjoying the game
Both ways are optional which i have used but maybe at some point in the future we could have this as an option shape to have, a bit like how you can build a stone wall/house in Sons of the forest?
This will be the one main thing that I have been waiting for the most, I do love exploring and leaving a POI's on a map, just for my own information.
for me, I'm more excited about the things that we do not know what's going to be in the new update!!!
I guess this is where we need a windmill Grinder and when we get the option of movable objects (central pivot) surely this is a nailed-on building?
I am sure at some point there will be a plug-in for this like the one in the java version
Stunning, please tell me what other game out there can allow you to do something like this!!!! (without mods)
Merry Christmas to you too, there will always be someone who wants to make trouble for other's enjoyment, but in my experience (although it is hard) is just not respond to those who try.
Hi I have also just logged into it ok, but as far as I can see it's still the "test island" that Red released ages ago, so that would be down to the server owner who I'm guessing is no longer around to update it.
I do hope you are just joking, but just in case have a read of this https://www.britannica.com/science/physics-science

This is something that is planned under the "movable structures" which if I remember there will be a central element pivot point to which we can attach an object like the above, but I would say this is way off from being implanted.
If this is possible (never tried it) I guess it would be the "Worlds" folder, so if it's the new Unity version this will be C:\SteamLibrary\steamapps\common\RisingWorld\New Version\Worlds. ( and just look for the one that you have created for this)
But the other way that you could do this is by making blueprints, maybe build some sort of building with each floor showing the different types of blocks/items??, at least this way other players could include this within their own worlds!.
Hi Red with the last update now includes posters and decals which are all great but I have always wondered why GIFs are not a thing.
I think having the ability to include Animated GIFs in our world would make everything more "alive" Now I do not know if having a load of these say on a server would affect the performance or even if it's down to copyright but it would be nice to see.
If I remember right this was a topic a while back and the overall census was not to have physics to structures, this is because some buildings can have 100's if not 1000's of different elements just in a single build, the idea works well for games like Valheim (modular building) but not for Rising world.
Just imagine that you have just built a massive house that has taken you weeks if not months to build for someone or something to make half of it collapse
