I've been making one fourth of a sky island that is about 400 blocks from one side to the next. I was hoping to only have to build that much of it and then copy, rotate and paste the rest as I usually do on smaller builds. But, my machine can't handle the air blocks and the island body. Is there a way I can copy only specific blocks or not copy the air blocks?
Don't believe so. If your machine can't handle it, just do it in strips small enough for your PC to work with, like 50 blocks wide by whatever long. Copy, rotate 180, paste then shift 50 in whatever direction then repeat.

/copy -a, I think
(or /paste -a)
