AI-built parametric CAD
Tell an AI what you want to make and refine it in plain language. Instead of a one-off 3-D file you get a forge — a self-contained web app for that part, with just the controls that matter. Share it, and anyone can dial in their own version and export something to print.
The forges below are live — open one, change a parameter, download a part to print.
Example forges
A planter, cup, or vase. Set the facets, taper, twist, and wall, toggle a drainage hole, then export a part to print — thin the wall and the forge flags that it won't print cleanly.
A parametric standoff: pick a screw-size preset, add a base flange, set the clearance bore. The simplest forge to crack open if you want to see how one is built.
Native fillet and chamfer, routed to the exact-geometry (OCCT) backend — the one this forge uses to export STEP for downstream CAD.
Keyframe animations, camera cues, and assembly steps — play the lid open or walk the build order a step at a time.
Take it further
In the wildThe Drum Machine — a parametric capstan drum, built as a forge for a real robotics project. Configure it, then export a part to print.
