I am working on a technical questionaire for a traveling show coming into our school and have some questions on terms (this is the first non-school show during my seventeen-year tenure, and I don't do lighting/sound for our own shows). Because I run the light and sound boards for concerts throughout the school year, this form was directed to me (we have a new drama instructor for next year AGAIN, and she hasn't started yet - don't know about her theatrical background). I tried doing a "theater terms" search on the internet, but couldn't find answers to some of my questions. Please forgive the non-theatrical terms in my questions. 1) I have to get a measurement for the "Plaster Line to Furthest Upstage Pipe". Is that from the stage side of the Proscenium to the pipe furthest upstage with lights hanging on it? 2) How do I find the "Grid Height (if no grid, from floor to ceiling?)"? Where do I measure? They want me to send the following with this questionaire, if available (I'm not sure what they want): Hanging Plot, House Dimmer Board, Ground Plan, Electrical - Plan and equipment inventory, Section View HELP Please?!?!
