    QUESTION
  
  
    I would like to create a barrel ceiling on the inside of my structure. How can I accomplish this?
    
    
  
  
    
  
  
    ANSWER
  
  
    You can easily create a custom curved ceiling for a structure using a manually drawn ceiling plane.
  
  
    
  
  
    To create a curved or barrel ceiling
  
  
    - 
      Open 
 the plan in which you would like to create a barrel ceiling.
      
      
     
    - Using the Select Objects 
 button, click in an empty space of the room in which you would like to create a barrel ceiling and click the Open Object 
 edit button.
      
      
     
    - On the Structure panel of the Room Specification dialog that opens, uncheck the box beside the Ceiling Over This Room, then click OK to close the dialog and apply your change.
      
      
      
      
     
    - With the default flat ceiling removed from the room, you can now create a curved barrel ceiling. Select Build> Roof> Ceiling Plane 
 from the menu.
      
      
        - Click and drag along one of the exterior walls on which the straight sides of the barrel ceiling will rest to create a ceiling baseline.
          
         
        - Release the mouse button, move your cursor into the middle of the room and click to set the ridge top of the ceiling plane.
          
         
        - The ceiling plane will display as a dashed, pink rectangle.
         
      
      
        
        
      
     
    - Using the Select Objects 
 tool, click on the ceiling plane near one of its edges to select it and display its edit handles.
      
      
     
    - Use the edit handles to resize the plane so that it completely encompasses the area over which you would like the barrel ceiling.
      
      
     
    - When the ceiling plane is appropriately sized, select it and click the Open Object 
 edit button.
      
      
     
    - On the General panel of the Ceiling Plane Specification dialog that opens:
      
       
      
      
        - Place a check in the box beside Curved Ceiling, which will enable the options directly below it.
          
         
        - Click the radio button to the left of the Lock Inside Bottom Height to lock it, then set the Lock Pitch value to 0.
          
         
        - Press the Tab key on your keyboard to apply this new value without closing the dialog box.
          
         
        - Return to the Curved Ceiling section and assign an Angle at Eave (in degrees) value between 0° and 89°. 0° would give you a flat ceiling and 89° degrees, a full 1/2 barrel. Notice that when you press the Tab key on your keyboard, the angle values update so that they are symmetrical.
          
         
        - If you are not sure what Angle at Eave you should use, specify 45°. This is a good starting point, and you can make adjustments to this value at any time.
          
         
        - Click the OK button to close the dialog and apply the specifications.
         
      
      
        
        
      
     
    - To see your barrel ceiling in a 3D view, select 3D> Create Perspective View> Full Camera 
 and click and drag within the room or area that contains the barrel ceiling.
