3. Next create a new surface in the Project Explorer pane. To keep track of the
surfaces in our model, let’s call this surface the “West Rake”.
To simplify a few things, we are going to work this surface in the Properties pane
from the bottom up. This is because the Rotation Angle is taken from the center
point of the surface, so when adding a Rotation Angle, the starting coordinates
change. It is best practice to add the Rotation Angle first so you do not have to
enter the starting coordinates twice.
 Rotation Angle - rotate the surface 90 degrees. This will place the orientation
of this surface at a 90 degree relationship to the main floor surface. If you
look at the origin of this surface now you will see that it is not all zeros
anymore. It is displaced due to the rotation of the surface.
 Inclination Angle - set to 20 degrees just like the rake at the back of the
venue.
 Width - The width of the surface should match the length of the original
surface so that they line up. Enter in 200’ for the width of the surface
 Length - translates into the “depth” of the surface when the orientation has
been shifted to expand along the Y-Axis over the X-axis. Set the length of the
surface to match the length of the North Rake, which is 75’
 X, Y, Z - Since this surface starts halfway through the width of the main floor
surface and the main floor surface is 100’ wide, it is simple to figure out that
placing the surface along the Y-axis should be 50’. Since the surface Start
point is halfway down the length of the main surface, it is easy to determine
that to place the X-axis we would say 100’
4. To create the rake on the other side is exceptionally easy using the cloning
feature. Simply select the raked surface that we just created up in the Project
Explorer window named West Rake. Next to that title you will find the “clone”
