RADii is an open design and collaboration platform aimed at designers and architects. RADii Viewer enables you to subscribe and view content published from Rhino3D in real-time as it is being created, anywhere in the world. Content can be retrieved from a cloud server on demand as well as saved locally for future offline use. Subscribable content so far includes meshes, point clouds, curves/polylines, materials, messages, control and other users. You control the scale of the received content, general properties as well as the world it inhabits. The focus of the platform is direct project communication and collaboration for professionals and amateurs.
