Purpose-built modular shell design software

Design domes, tunnels, and shell structures with snap-first precision.

DomeCAD gives builders a focused workstation for triangles, hexagons, 254 mm modules, magnetic snapping, panel counts, 3D previews, and exportable build data.

Focused, not bloated

Modular shell geometry that turns into parts.

DomeCAD is a rules-aware layout tool for builders who need shape placement, snapping, counts, previews, and export data without learning a full 3D modeling suite.

01

Place

Build with triangles and hexagons on a shared 60-degree construction system.

02

Snap

Drag near valid positions and let magnetic snapping line up edges and nodes.

03

Inspect

Review panel counts, seams, nodes, area, module data, and selected part metadata.

04

Export

Generate project JSON, SVG layouts, CSV bill-of-materials, DXF geometry, and OBJ previews.

Why DomeCAD exists

General CAD can draw anything. DomeCAD helps you design things that can become modular shells.

  • Snap-first rules: 60-degree geometry, edge alignment, and module-based layouts.
  • Manufacturing metadata: panel family, channel depth, panel thickness, gasket logic, and future BOM rules.
  • Builder exports: practical files for CAD import, CNC planning, web previews, and project records.
  • Purpose-built workflow: one focused product instead of a blank modeling universe.

Key features

A workstation for modular shell layout.

Triangle + hex tools

Core shape placement with 60-degree rotation and shared lattice logic.

Magnetic snapping

Easy edge/node alignment that keeps layouts coherent and buildable.

3D preview

Flat, tunnel, and dome preview modes for quick spatial reasoning.

Panel metadata

Seeded DistroGrow SnapCell 10.25 family with 254 mm module context.

Export center

JSON, SVG, CSV, DXF, and OBJ files from the browser workstation.

Project persistence

Local saving plus account-based project records through MySQL.

Use cases

For builders working in modular skin, shell, and enclosure systems.
