Common diameters

Even footprints center between blocks; odd footprints use one center block. Mixed oval footprints use a center line on only one axis.

Dome blueprint workflow

  1. Set the source sphere diameter.
  2. Choose top or bottom half and cap height.
  3. Inspect the current layer, then export or print the layers you need.
  4. Use the share URL after confirming half, cap, and shell settings.

Dome blueprint outputs

  • Cap-aware dome layers with current-layer row segments.
  • Block totals for hollow or solid dome settings.
  • Selected-range print and CSV output for offline building.

Dome blueprint notes

  • Cap height changes the included layers, not the horizontal footprint alone.
  • Top and bottom halves have different build order expectations.
  • Print only the layers you will build in the current session.

FAQ

What does cap height control?

It limits how many layers of the selected dome half are included in the blueprint.

Can I print only part of a dome?

Yes. Choose Selected range, enter the layer numbers, then print the generated sheet.

Should I use hollow or solid?

Use hollow for shells and roofs; use solid when you need a filled mass or a conservative material estimate.
