No ceiling in the plan

How can I turn on the ceiling in the designer?

You can turn on the ceiling in the designer on the View tab located in the right-side icons by using    the button. This enables a ceiling with no thickness, similar to the walls. For a ceiling with thickness, you can use the wall block found in the Accessories1/Basic Shapes group, or by rotating a manual wall from the Accessories2/Walls group into the scene.
