1. What is the difference between presentational material and the working drawing?
Presentational material, a rendering or scale model, is used by designer to present his ideas to the director, producer and cast.
Computer Model Designer Boyd Ostroff created the presentational material for this OperaPhilly production of La Boheme on a Macintosh using Strata StudioPro 2.1. Like the more traditional watercolor or pastel rendering, the computer generated 3d model can show how the set will appear under theatrical lights. The working drawings are the "blue prints" -- floor plan, front (or designer's) elevation, painter's elevation, cross section, detail drawings -- used by the production crews to build, paint, and assemble the set on stage.
The Opera Company of Philadelphia has posted a nearly complete set of drawings (Computer Models, Scenic Photos, Floor Plans, Section Views, Designer Elevations and Shop Drawings) for a number of the operas they have produced. Go to their Technical Production Web Page. While there explore their shop (OCP Production Center) and the opera house (Philadelphia Academy of Music) in which they perform.
2. What is a rendering?
A rendering is a colored sketch of the finished set as it will appear, under light, to an audience member seated in the center of the house. Today many designers create their renderings on a computer using both a CAD program (VectorWorks) and rendering software such as Art*Lantis or RenderWorks. Link to the computer generated renderings for Northern's 2005 production Disney's Beauty and the Beast. or to some of my early experiments with the demo version of Art*lantis 4.5
3. Which, a rendering or a scale model, better illustrates a designer's concept of how the set will look under light?
A rendering.
4. Which will best help the director understand the stage space with which he has to work?
A scale model.
What is a virtual model?
Unlike pencil drafting where the designer is forced to work in only two dimensions, on a computer, the two dimensional world of the ground plan and elevation can be extruded into a three dimensional world. The virtual model can be viewed in perspective from the front, side, top, and back. Using Flyover Function it is possible to view the virtual model from any seat in the house.Below is a view of the virtual model I created in VectorWorks 8.5 for one of the two major sets in Northern's spring 2002 production of David Lindsay-Abaire's Fuddy Meers.
Virtual Model: Gertie's Kitchen, Fuddy MeersThe 10'x12' kitchen wall plus the three 12' tall masking units were created using the Wall Tool. The 4x12 wagon plus the kitchen appliances (the stove, sink, counter, and refrigerator) began as simple 2D rectangles which were extruded to give them height. The two figures were imported from another drawing and the table and chairs were symbols included in the VectorWork's Architectual Tool Kit. Below is a photograph of the set as it appeared on stage.

5. What is a floor plan?
A top view of the set. The floor plan is used by the crew to locate the set on the stage floor.
6. What are the conventional plan symbols for a door, windows, flat, step unit and platform?
7. What is the difference between a Designer's (or front) elevation,
A Designer's Elevation is a front view of each individual piece of scenery. The designer's elevations are used by the shop crew to determine the height and architectual detail of each scenic unit.
Painter's elevation,
A Painter's Elevation is a copy of the front elevation which has been rendered to indicate the color and painting techniques which are to be applied to the final set. .
Cross section, and
The cross section is a side view of the set
Detail drawings?
A drawing that describes the details of a scenic unit or prop. It is usually drafted in a fairly large scale, typically between 3/4 " = 1' 0" and 1 1/2" = 1' 0".
