The web’s 3D format, with real tools
glTF is the format the web runs on, compact and fast, which is why AR assets, product configurators, and online model libraries ship in it (GLB is the same thing in a single binary file). Most glTF viewers stop at “look, it spins.” This one gives you the working toolset: section planes to see inside, a part list to show, hide, or isolate components, full-color rendering, and true measurements in inches or millimeters, which is exactly what you need when a downloaded asset has to fit a real-world space or part.
Share it with your setup staged
Save the model to a free account, pin notes to the geometry, attach reference documents or images, and share one link. The person receiving it sees the model with your measurements and notes already in place, joins the discussion on the part itself, and pays nothing. You control downloads, permissions, and how long the link lives.
Free, and staying that way
Built and owned by Texas Metal Works, a fabrication shop that made this for its own teams and shared it. Free as in beer; the optional paid plans just keep it from being a cost center. About us.
