The preview window displays an elevation view of the roof that updates dynamically to reflect the actual dimensions of the roof including the difference in elevation between the front and rear wall plates. You can also estimate a roof pitch by eyeballing it from the ground from the gable side with a level and ruler. You can calculate slope area rafters length and other dimensions.
