I have a two-story house plan. I would like to place the roof of my structure on floor one and have it ignore floor two, such as for a story and a half, or Cape Cod style building.

Is there a simple way to accomplish this?  


By default, Chief Architect will place a roof on the top of the highest story in your structure. For example, if you have a two story structure, an automatically created roof will be placed on the second floor. You can, however, specify that the top floor be ignored when the roof is created.

To build an automatic roof ignoring the top floor

  1. Open the two-story plan to which you would like to add a roof.

  2. From the menu, select Build> Roof> Build Roof to open the Build Roof dialog.

  3. On the Roof panel:

    • Check Build Roof Planes.

    • Check Ignore Top (#) Floor.

    • Specify the desired pitch, overhang depth, or other information as needed.

    • Click the OK to build your roof.

  4. Notice that the roof planes do not display on the top floor in floor plan view, but are instead displayed on the floor below.

  5. To confirm that the roof planes you created rest on the floor below the top floor, create a 3D view by selecting 3D> Create Perspective View> Perspective Full Overview .
