Display states
The following states are available for displaying parts in Hull Viewer:
When Hull Viewer is started, the previous displayed state Shaded or Wireframe is restored.
Set the display state to Hidden if you want to hide parts temporary without removing them from Hull Viewer. Hiding a large part may be useful in order to see the parts behind it. For the same reason you can make a part transparent. Selecting Opaque will remove the parts transparency state.
The X-Ray state can be used to examine an object. When in X-Ray mode, the object can be seen through other objects so that it is always visible. Objects in front of the object being X-Rayed are made (partly) stippled are transparent (see Display).
