DomeSketch vs Acidome
A browser 3D constructor (acidome.com, acidome.ru) with icosahedral and octahedral bases, frequencies to 18, Class I and III subdivisions, four subdivision methods, several connection types, timber cut lengths and angles, cover and tent patterns, and an .obj export.
Where Acidome leads
- Far more geometry than DomeSketch: octahedral domes, Class III, Kruschke and Mexican subdivisions, fullerene trims, frequencies to 18.
- Beam cut lengths and face angles for a chosen timber size and joint type — the numbers a sawyer needs, which DomeSketch does not give.
- Cover and tent panel patterns, a scheme view, and a framework .obj export; eleven interface languages.
Where DomeSketch does something it doesn't
- Metric only; no feet or inches anywhere.
- No materials estimate, no openings, no site features, no build sequence; the URL carries the geometry but not a design.
- The result is a frame — anything about the building it becomes is left to you.
Pick Acidome if
- You need a geometry DomeSketch doesn't do, or timber cut lengths and angles.
- You work in metric and want an .obj for CAD.
Pick DomeSketch if
- You want the dome as a building: door, windows, riser, pad, rainwater, materials, and a plan to build it.
- You want the design as a link you can hand to a builder.
The run — 20 ft · 3V · 5/8 sphere, 2026-09-20
Entered: Icosahedron, 3V, Class I, Equal Chords, 7/12 of sphere, radius 3.048 m, Piped connection.
- Edges 3 kinds (165): A 80, B 55, C 30; faces 2 kinds (105); vertices 3 kinds (61); max triangle side 1230–1257 mm; height from base 3.62 m
- DomeSketch: 165 struts 80 / 55 / 30, 105 panels, 61 hubs; longest strut 4.124 ft = 1.257 m
Counts match exactly and the longest chord matches to the millimetre. Acidome reports beam cut lengths (953–1147 mm) net of the joint rather than vertex-to-vertex chords, and its 7/12 is the same vertex-ring cut DomeSketch calls 5/8. Height differs by the base convention.

About our side of this page
DomeSketch is our product; this page is written by us. Its numbers for the run are computed from the geometry when the page is built and are the same as the reference table. What DomeSketch does not do:
- Class I icosahedral only, 1V–8V: no octahedral, no Class II or III, no Kruschke or Mexican subdivisions (Acidome, Simply Differently).
- No bevel, dihedral or mitre angles and no timber cut lengths net of a joint (Geo-Dome, Acidome).
- No reverse calculation from a strut length (Domerama, Desert Domes); no lath cut optimisation (Simply Differently).
- Feet and inches only in the interface; millimetres only in the STL export.
- Prices and mix yields are placeholders and the page says so; the materials estimate is rough.
- No hub cut deductions for any specific connector (Sonostar).
