OpenCAD STEP Viewer

STEP (ISO 10303-21, AP203·AP214·AP242) Open 3D CAD files (.stp·.step·.p21, compressed .stp.gz·.stpZ·.zip) in your browser without installation or registration. You can view assembled product trees, part colors, units, layers, wireframes, PMI annotations, file head information, select or hide parts or faces, measure the distance between two points, and save the screen as PNG.

The file is read and rendered entirely within your browser; it is not sent to a server. A modern browser that supports JavaScript and WebGL2 is required.
