I do a lot of shingle style houses. The walls frequently flare out as it meets the foundation wall. I have done this by adding a curved sweep to the base of the wall. When I do this the fill pattern turns upside down and can not be rotated. Also a line is created where the sweep meets the wall. This is undesirable. The line can be deleted with the line work tool, but is occur in every exterior view. Rendering this also results in an incorrect orientation of the map. See attached example.
