Why there is no ceiling
How to handle the following situations:
- When the ceiling does not display in 3D top-down view, you need to switch the view to 3D bottom-up view or Walkthrough mode.
- If the ceiling layer is missing in Walkthrough view, you can check ""Display"" – ""Custom finishing"" and ensure ""Ceiling layer"" is checked. Shortcut: Ctrl + Shift + Z.
- If the walls are not closed or properly connected, there will be no ceiling. You need to check for wall issues in 2D view.
