    Hello Paul,
    thank you for posting this question on Architect 3D forum webpage.

    All Architect 3D editions are capable of creating flat roof. Just go to the Roof plan then select Freehand Roof drawing tool, draw the roof shape, select it and set the pitched angle to 0 degrees. This is how flat roof is drawn.

    While previewing the drawing in 3D plan, please drag and drop concrete surface material from library onto the roof so it appears as you want it.

    Alternative approach to achieve the same result is to set the elevation of concrete floor above the wall’s height on this level.

    Kind regards,

    On a similar subject, how can i take a hip roof and then put a table top (flat) roof on? It doesn’t seem to work using the dormer cut out. Also, the free form drawing tool does not seem to support such a shape. Thanks Jeremy

      Hello Jeremy,
      thank you for commenting on Architect 3D forum.

      Hip roof with flat area on top isn’t included as pre-set, but it is possible to construct with precise measuring and careful drawing.

      Start from the flat area by drawing zero degree tilted rectangle roof piece. Use either the Freehand Roof tool or Rectangle tool on Details tab.

      Once the flat area is drawn, move on to draw the four slops. Keep these slops flat as well and the side length equal to all!
      Grab one of the ends of the Pointing arrows and rotate all to point away from the flat area.

      Now make sure the Laser Alignment in Properties is selected and grab one of the outside corners of a slop panel and drag it in a straight direction to the exact distance of the neighbour slop. Repeat that to joint all corner tips together.

      After that select one slop and hold down Shift on the keyboard to select the other three slops. In Properties in section Elevation chose (Peak) and as a Pitch Angle type in 28° then press Enter.

      Go to 3D plan to preview.

    Apols- setting slop to edge means you can build up such a roof. Thanks
