Allows the Renderer window to synchronize with the model or selected objects in the Main view. By default, the Renderer window is unlocked.
From the Renderer window, click the Lock to toggle the command to Unlock .
The Renderer automatically raytraces and then renders the model or selected objects.
The raytrace and reload performance depends on the size and complexity of the model or selected objects in the Main view. You can click Stop at any time to stop the rendering. The Renderer window displays only the data that has been loaded. You can also lock the Renderer window, navigate to a smaller, less dense section of the model or select individual objects and then unlock the Renderer.
