Blueprint notes
- Even footprint: the center is between four blocks, so mark the 2×2 center area before mirroring.

Odd vs Even Center
Odd footprint (like 31)
Has one exact center block. Perfect symmetry around center.
Even footprint (like 32)
Center is between middle blocks. Mark the shared center line or 2×2 area before mirroring.
Common diameters
Even footprints center between blocks; odd footprints use one center block. Mixed oval footprints use a center line on only one axis.
Center-check workflow
- Choose a diameter or oval size.
- Read the Center type card before placing blocks.
- Mark the center block, center line, or 2×2 center area.
- Only then follow the row segments and mirror the footprint.
Center-guide outputs
- Center type, center instruction, axis markers, and row segments.
- Warnings for even or mixed odd/even footprints.
- Printable or shareable reference for the selected size.
Center mistakes to avoid
- Do not start an even circle from one block as if it were odd.
- Mixed odd/even ovals need a center line on only one axis.
- Mark axes before counting long row segments.

FAQ
What is a single center block?
It appears when both footprint dimensions are odd. The build mirrors around one block.
What is a 2×2 center area?
It appears when both dimensions are even. The true center is between four blocks.
What does one-axis center line mean?
It appears when only width or height is even, so only that axis is centered between two blocks.
