This shows the correct angle for other lines parallel to the top and bottom of the building. This a a simple example of how to build a roof line or any other inclined plane when using two point perspective. The 3d drawing also differs very slightly from the line drawings including a false hip connecting the front porch to the bedroom hip to its right and some false roofs over the unseen shed roof and how the garage roof connects to the main roof and lack of crickets.

Draw two edges from the top of your vertical line to the corners of your roof. The 45 degree angle lines represent the hips. Step 11 draw a vertical line thru the center of the x and draw the front one as high as you want the roof to be. In this step i have drawn in some dashed lines.

Create a structure to put the roof on. Cursor changes to a transparent disc to gauge drawing height. The other 2 lines the horizontal and vertical line are there to make an imaginary box. Use the following steps to draw a roof.
