Common diameters
Even footprints center between blocks; odd footprints use one center block. Mixed oval footprints use a center line on only one axis.
Preset workflow
- Confirm the preset size in the input panel.
- Check the center guide and mode before collecting materials.
- Use the preset as-is or adjust size, thickness, shell, or cap settings.
- Export the final blueprint only after the preview matches the intended build.
Preset outputs
- Preloaded blueprint plus editable controls.
- Example block totals and row or layer counts below the workspace.
- Related preset links for nearby sizes.
Preset notes
- Presets are starting points, not locked templates.
- Changing any setting changes the export payload and share URL.
- Use related presets when the first size is too small or too large.

FAQ
Can I edit a preset?
Yes. The preset only sets the initial values; all controls remain editable.
Does the example output update if I change the tool?
The below-page example describes the preset default; the live tool output updates immediately in the workspace.
Should I canonicalize a preset to the main tool?
No. A preset has its own canonical URL when it serves a specific size task.

- Forgetting that spheres and domes should be built one layer at a time.
