Abstract
A first user having a certain set of privileges with respect to an initial three-dimensional (3D) model associates a watermark with the initial 3D model, so that the watermark is displayed whenever the initial 3D model is viewed or edited. A second user having a smaller set of privileges with respect to the initial 3D model is permitted to view, copy and/or modify the initial 3D model, but is not permitted to remove or alter the content of the watermark. The watermark is continuously displayed as the second user works with the initial 3D model. When the second user applies a change to the initial 3D model, an indication of the modifications applied by the second user is generated and stored with the model data corresponding to the updated 3D model.
