In Toolspace, on the Prospector tab, expand the surface Masks collection and click the mask’s name.
The mask is displayed in the Prospector item view. In the Prospector item view, you can manipulate the view of the mask, including zooming, panning, rotating, and orbiting. You can also save the view to an image file.
Note: A render-only mask must be rendered before you can view it.
Right-click anywhere in the item view and select the option you want, such as Zoom To or Pan To.
