MeshMarkup is where 3D work gets reviewed with clients. Upload a 3D model and send one link. Your client opens it in any browser, with no account and nothing to install. They click the exact spot they want changed, and the note stays pinned there along with the camera angle they were looking from. You open the note and see exactly what they saw. No more "the bit on the left", feedback scattered across email, chat and screenshots, or clients who can't open the file. What you get: • Notes pinned on the model, each with its camera view, replies and a status (open, in progress, resolved, won't fix) • Versions: upload v2 and the open notes carry over; Compare shows what changed • Sign-off: the client approves a version in one click, on record • Email notifications, and you can see when a client opens your link • Internal notes and @mentions your client never sees • A printable report of every review round • GLB, glTF, FBX, OBJ, STL, PLY, DAE, STEP, IGES, Rhino 3DM, 3MF, 3DS and zips, including large CAD assemblies Built for 3D artists, product visualizers, industrial and furniture designers, studios and agencies, and engineers who share CAD with people who don't use CAD.
