SpaltX Forge — parametric CAD
From words to watertight
Describe a part, tune it with live parameters, export it to a printer — all in the browser.
How it works
01
Describe
“Enclosure 60×40×25, 2 mm walls, M3 lid screws.” The engine writes the script — or start from a template.
02
Compile
A deterministic kernel builds exact geometry in your browser.
03
Export
Saves become revisions. Export STL for the printer, or share the script.
const params = {
mastD: { value: 12, min: 4, max: 30, step: 0.5, label: "Mast diameter", unit: "mm" },
};
function build(p, f) {
let mount = f.rect(42, 42, { r: 5 }).extrude(5);
mount = f.merge(mount, f.cylinder(p.mastD + 8.2, 22.5).move(0, 0, 4.5));
return f.subtract(mount, f.cylinder(p.mastD + 0.2, 28).move(0, 0, -0.2));
}In the studio
Pro modeling ops
Sweeps, lofts, coil springs, ISO threads, involute gears, engraved lettering.
Live parameters
Sliders regenerate geometry as you scrub.
Design engine
Describe a part, get an editable script.
Viewport analysis
Section planes, measure probe, center of mass, cost by material.
Print-ready export
STL free; 3MF, OBJ, and PLY on paid plans.
Share and collaborate
Shared workspaces, pooled seats and credits, public links, revision diffs.
