MeshMarkup vs Autodesk Viewer

Autodesk Viewer is a free online viewer for 2D and 3D designs, and good for a quick look at a native CAD file. MeshMarkup is for what comes after the look: the client’s notes on the model, the next version and the sign-off, with nothing expiring halfway through the job.
