DomeSketch.ai
Domes, planned in seconds. Choose a style, size and materials — get every strut length, hub and panel count, a rough materials cost and a 3D model you can spin around and save. Then plan how to build it: robot-assembled, cement-printed, AirCrete, or earth-insulated.
Cedars and bushes for scale only — they're in no count or estimate, and they stay clear of the door, pad and drum.
A stud-framed stem wall through the base hubs that lifts the dome for headroom at the edge and a door without a dormer.
A dormer: a vertical frame at the base ring with side walls and a roof back to the shell. Panels and struts it crosses are cut to the frame.
Vertical boxed windows with a sill, cut into the shell like the door — up to 6, each with its own small dormer.
A round slab under the base ring with an apron, an optional thickened edge, mesh or rebar, and an anchor bolt at every base hub.
A gutter ring at the base feeds a drum set in the ground; a drip line around the dome irrigates from it.
3V base ring is not flat: hubs differ by up to 1.9". Plan a stepped base plate or trim the base struts.
