Plinth 3D Review

Productivity

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Present a 3D model, pin feedback on it, and get a clear client decision — Approved or Request Changes — with a PDF sign-off record. USDZ in, decision out. Plinth turns 3D client review into one clean loop: import a USDZ model, pin feedback directly on the geometry, send your client a review link, and capture a clear decision — Approved or Request Changes — with a PDF sign-off record. Built for product and industrial designers, furniture and hardware makers, and anyone who presents 3D concepts to clients and needs a real decision back. WHY PLINTH • Comments live ON the model — pins are anchored to the 3D geometry, not to a screenshot or a video frame • A formal decision step — your client taps Approved or Request Changes (with an optional note), and that decision comes back to your dashboard • A sign-off record — export a clean review PDF with the decision, comments, and signature lines • No client account needed — clients open your review link in the free Plinth app and respond; they never pay HOW IT WORKS 1. Import a USDZ model from Files 2. Orbit, inspect, and pin review notes on the model 3. Publish a review link and send it to your client 4. They review and decide — you pull the decision back, status updates, done 5. Export the PDF sign-off for your records WHAT'S IN THE FREE VERSION Import and present your model, pin comments, and complete one full client-approval loop — free. Plinth Pro unlocks unlimited projects, unlimited comments, unlimited review links, and clean unbranded PDFs. HONEST SCOPE (v1) Plinth is early software, built in the open. Today it's iPhone/iPad with USDZ import; review links open in the Plinth app. Browser-based review, more file formats (glTF/OBJ/STEP), Mac, and spatial review are on the roadmap — tell us what you need first.
