How to use it
4 steps
- Set the width (east–west) and the length (north–south).
- Pick the wall: thin, thick (no diagonal gaps) or filled for a floor.
- Follow the runs: the numbers on the grid are the blocks in each straight run; coordinates count from the true centre.
- Build or export with phone build mode, the A4 sheet or a schematic file.
Questions builders ask
How many blocks is a 31 × 19 oval?
72 blocks for a thin outline, 96 for a thick one and 469 to fill it.
How do I read the oval pattern?
Start at the middle of the top edge and count the blocks of each straight run going clockwise: for 31 × 19 it is 9-4-2-2-1-2-5. An oval has a different pattern on the long and short sides, so the generator shows every run on the grid.
What size oval do I need for an arena?
A 64 × 48 oval is a common arena size: 156 blocks for the outline, 2,404 for the floor. Use thick for a wall with no diagonal gaps.
Can I make an oval tower or a dome on an oval?
Yes. Set the layers (tower height) and switch on "Add a dome on top"; the dome follows the oval base. The dome generator also takes a separate width and length.
