When I build my roof I get a roof eave on the edge of a lower wall. Why is that? How can I get rid of it?


This is normally caused by not having the walls lined up vertically. To resolve this follow these directions to line up your walls vertically.

To align walls vertically

  1. Select the wall.

  2. On the edit toolbar click the Align with wall below or Align with wall above edit button.

  3. Finally, select Build> Roof> Build Roof ,and click OK to rebuild your roof.

You should now no longer have the unwanted roof eave.
