What it does
CADAM is a web app that turns text descriptions, and optionally reference images, into 3D CAD models: the kind of precise designs used for engineering and 3D printing.
It finds the important measurements in the design and gives you sliders to change them instantly, without asking the AI again. You can export the result as STL, SCAD or DXF files.
There is a live version to try in the browser with nothing to install. Running your own copy needs keys for several AI services.
Who it's for
Makers, 3D-printing hobbyists and engineers who want a quick way to create custom parts.
Can I use it without coding?
