Did you know that schematica will even build for you? Its not like world edit where it just pastes the schematic into the world, as long as you are carrying the blocks etc it will place the blocks etc down when you use the print command. It will only build at the same rate as placing the blocks yourself and only as far as you can normally reach. IE enable printing, have as many resources as you can carry and just walk around your ghost image to see it get built. Now would be a good time to learn how to do this, not 5 minutes before the world gets reset.
