As you read in the prior post after the working drawings are delivered the Technical Director makes build drawings. I will only post a few here.
This drawing is an elevation. To the left you can see the first row of the balcony as well as the height of the set, the level of the first row of the orchestra and the opening under the stage where we bury all the bodies. Just checking to see if you were reading it's called the trap room. More about that when we get to LaMancha.
