I am modeling an apartment or single room which does not require a roof to be generated, or simply do not want a roof generating over an enclosed room area, such as an outdoor patio.  How can I stop the automatic roof generator from puttinga roof over this area?


In Home Designer, it is easy to create a room that is open to the sky.

To prevent a roof from generating over a room

  1. Using the Select Objects tool,click to select the room over which you no longer want a roof to generate to highlight it.

  2. Click the Open Object edit button to display the Room Specification dialog.

  3. Select the Structure panel, uncheck Roof Over this Room.


  4. Click OK.

  5. Repeat this procedure for any remaining rooms in the plan over which you do not want a roof to be generated.

  6. Select Build> Roof> Build Roof from the menu and in the Build Roof dialog, click OK to rebuild the roof.

    • In Home Designer Pro, make sure that you check Build Roof Planes before clicking OK.

    • If you have Auto Rebuild Roofs checked in the Build Roof dialog, this step is not necessary.

    • Note:  Auto Rebuild Roofs is not available in Home Designer Essentials.
