How do corner stones work?

[beemancer]

Can you actually plug in corresponding blocks from Inventory to corner stone without having to buy the Blocks and blue print? I can't seem to do that or I am doing it wrong?

[AvilerED]

Blueprints are building guides, not autobuilders, if that's what you are asking.

[Hoki]

you always have to build them yourself (or with some help by other folks). like aviler said the corner stones are simply guides.

since R31 (the lastest update currently) you can get them for free and buy all required blocks with coins). but no matter you farm them or cash them you gotta place them 1 by 1 by hand

First you level (make it flat) an area of terrain, big enough to fit the building you intend to build. The last bit is important, because the fort, to name one, is larger than a claim by five blocks, while the Small Traditional House takes about one fourth of a claim.

If you are of that lazy type, you can deploy the cornerstone above water, so you start already with the leveled area.

Afterwards you drop the cornerstone on the selected are. Be aware that different cornerstones have different deployment positions. Some are in a corner of the building, but others are in the middle. The facing your avatar looks when you deploy the cornerstone is important too.

If the intended area is facing North-South, and you deploy the cornerstone while lookng East-West, the cornerstone will deploy wrong. Pick it up, correct your position, and deploy it again.

Once you have the cornerstone in the right place and with the right facing, a blue outline of the building will appear. At this point is when you interact with the cornerstone to activate it.

The blue outline of the building will disappear, and in its place will appear a smaller copy of the blocks you need to place (by hand, one by one) in their respective positions. Those small blocks are called hint blocks, as they hint at the block type that goes in a certain position.

So, if you see a small Stacked Stone Wall block, you know that you have to put a Stacked Stone Wall block in the position. If you have the right block selected in your quick bar, the hint block will get a green box around it, telling you you can drop the block in place. If the block type you have selected does not correspond, the box will be red.

Keep putting blocks in the indicated positions unrtil you finish the building.
