Um, I’ve built a tall building and when I came back about 7 of the blocks were missing at the very top. I thought maybe a needed a beacon and plotter to expand upward, but that doesn’t seem to be required. It recognizes the beacon below.
Any ideas why blocks are disappearing? I’m certain it was complete. I spent time viewing the complete build from different directions.
Thanks!

A plot is 8 voxel blocks by 8 voxel blocks.
You have to plot up, plot down, …everyplace you want to build. It’s not automatically plotted to the sky.
If you place a block and it has an orange outline, it’s outside of your plots and will disappear.
If you have a tall building, you’ll need to plot it every 8 voxel blocks.
Thank you, appreciate it!
Ok, I’ve placed the beacon all over in different areas and no matter where I put it, it says the plot is reserved by another beacon… ah… nevermind. I’m playing with a miner alternate.
Thanks again!
Another thing that might be handy in Knowledge → Tips → Worlds … make sure the World Regeneration does not have a check mark by it.
This way, any time you place a block outside of a beacon by accident you will get the following popup on your screen.
If it is directly above one you already have, you don’t need a new beacon, just the plotter. 
If it is saying reserved, probably because it is my plots there. But anything directly above and below what you already have will be reserved by you, so you can claim them with a plotter.
Yes, I think I just need a plotter! I came back because I’m still getting the reserved message! Thanks, Paka!
Also, very helpful! Thanks!
Hmm, is it directly east of the miner’s place there? I can fix that actually… I’m pretty sure I can make it so you can plot in the reserved areas I have if that is where it is. I’ll have to do it in the morning though when I can get back on that character. 
I think it will be fine once I climb back up there lol I am about to, but I just learned something NEW while doing this! In Build mode, I can reach WAY HIGHER with my hammer!! LOL
*makes total sense.
Yep (something like 20 plots later) LOL My plotter still works.
Press “B” when building …
It shows you the space wich you have plotted 
And wich you can safely build without the blocks getting regenerated outside the beaconed area 
Another trick, if you don’t have the plot view on - look at the outline before you set down a block. If there is a green outline, that’s yours, you’re good. If orange, it isn’t plotted.
