PartWork.ai 3D Viewer – CAD, STEP & STL Files

PartWork.ai 3D Viewer puts an interactive 3D viewer on any page or post. Your visitors drop in a STEP, STP, STL, IGES, IGS, OBJ, DXF, BREP or GLB file and see it in 3D: rotate, zoom, switch views and go fullscreen, on desktop or phone, with nothing to install.

It’s built for sites whose customers send CAD files: machine shops, 3D printing services, fabricators, makerspaces and engineering firms. A customer can check their file on your “request a quote” page before they send it, and you can ask for exactly the file you need.

The plugin adds:

• A PartWork.ai 3D Viewer block, with a live preview in the editor.
• A [partwork_viewer] shortcode for the classic editor and page builders.
• Settings for title, light or dark theme, height and colors.

Free, with a credit link

The viewer is free on any site. It shows a small “Powered by PartWork.ai” link inside the viewer, which must stay visible. For a viewer without it, ask about a white-label license at support@partwork.ai.

External services

This plugin embeds the PartWork.ai viewer, which is hosted by PartWork.ai and loads in an iframe from cdn.partwork.ai on pages that contain the block or shortcode. The plugin adds no script to the rest of your site.

What the viewer sends, and when:

• Every time the viewer loads: an anonymous usage event (which viewer surface loaded and the origin of the page it is embedded on) is sent to api.partwork.ai. The viewer stores a random visitor ID in its own storage on cdn.partwork.ai to count repeat views. No cookies are set on your site, and no name, email or account is involved.
• When a visitor opens a STEP, STL, IGES, OBJ, DXF or BREP file: the file is uploaded to api.partwork.ai to be converted for display. Before the upload, a Cloudflare Turnstile check (challenges.cloudflare.com) confirms the visitor is not a bot. GLB files open in the visitor’s browser and are not uploaded.
• When a visitor clicks “Modify with AI” or “Open in Studio”: a new tab opens on studio.partwork.ai. Nothing is sent before the click. You can hide the button in the block settings or with ai="off".
