  1. Draw two straight walls using one of the Straight Wall Tools , such as an Exterior Wall .
  2. Next, draw a curved wall of the same type, such as Curved Exterior Wall , connecting the straight walls as shown below. Don't worry about positioning it perfectly: for now, just approximate the curve.

  4. In the Radius of Tangent Curved Wall dialog, specify a Wall Radius and the walls will be shortened or lengthened to accommodate this new radius.

  5. Your final result will be something similar to this:
