Preview and build a row of up to ten repeated pieces.
Lock a piece in Enhanced Build Mode, then tap Confirm to enter the repeated-row preview, called zoop. Aim to either side of the locked piece to change the row length. Origins are spaced 2 metres apart by default; hold the 1 metre or 4 metre spacing modifier to change that. Hold Confirm for one second to build the row, or tap it again to leave zoop. Every piece uses normal materials and placement checks; a blocked preview cannot start building, and construction can stop if resources run out.
You can change zooping distances in Configurations.
