It would be really good if you could spawn a blueprint from the Factory in the Survival mode so that the spawned structure gets connected to an existing base. That is, it would work the same way as when placing a block with the "Connect to Base" option on in the "N" menu. The spawned structure could be placed either adjacent to the existing target base or physically separate. Both would "snap" into the existing grid, though, the same way as when placing single blocks. This would allow you to build your base incrementally in a survival game using the factory. For example, you'd first spawn a small structure containing the most basic functionality, then you'd add more structures to it, like gun towers, a greenhouse, a hangar, a large warehouse for more storage etc. There's currently the possibility to do sort-of-copy-pasting but that only works in Creative and it doesn't do it incrementally i.e. you'd need to keep updating your blueprint instead of simply building something using modular pieces. And since it's Creative none of it is available for Survival play where it would benefit you the most. The user friendliest way to add this would be to just make it work the same way as the existing "Connect to Base" option but with blueprints instead of just single blocks. The "Core already exists" issue could be handled by simply automatically deleting the Core block in the spawned object if it gets connected to an existing structure that already has a Core block.
