But be careful that the situations 02 and 03 cannot get them as in the 1 where you made the view of the red cube in shady mode and that of the cube emptied in removing hidden lines; in view 02 and 03 you will have to make a single view and if you impose it in removal mode hidden lines, as you did, you will not see the red color of the cube; you must therefore use the shaded mode and consequently you will see the color of the empty cube (in this case it is white so I don't think it is a problem, but if you use other colors it wouldn't be good)
