set design
The biggest challenges
David faces when designing a theater set is that budgets for community
theater are very tight, the construction time frame is very short, and
rehearsals often take place on stage while the set is being built.
Additional information about David's approach to set design and the
technologies employed are discussed in his
Autodesk University presentation "The Show Must Go On: The Art and
Technology of Virtual Set Design".
Recent sets for local and regional theater productions, include:
American Son

(click to expand or collapse)
(January 2026)A new director approached me and said, "I heard you made it
rain on stage." That was the start of our work together on American Son, a
gripping 90-minute contemporary drama that explores race, biases, and family
dynamics in America. In it, an estranged interracial couple wait in the
Miami Dade County police department at 3:30am for news regarding their
18-year old son, who was detained following an unspecified traffic stop.
I wanted the set to reinforce the tension by having them
appear lost in a large, impersonal institutional setting while a
thunderstorm rages outside.

Once again, I turned to Revit to design the set. The
structure was quite simple, consisting of standard flats and framed walls,
meticulously painted to look like concrete block. By turning the room
90-degrees, I was able to create the illusion of long hallways on either
side. The rear wall, which appears to be large windows, was actually just
painted lumber. The set also had ceilings in some areas, which was something
I had always wanted to try. That simple touch made the set incredibly
believable.

I also used Twin Motion to create the animated
thunderstorm, complete with flashes of lightning, and an occasional passing
vehicle.

Sister Act
(click to expand or collapse)
(November 2025)The set for musical Sister Act presented a unique challenge:
creating more than 20 unique settings for the 27 individual scenes that
range from the a night club to a police station to a neighborhood bar, not
to mention multiple scenes inside a large Cathedral in downtown
Philadelphia.

Happily, the theater has a large rear-projection screen
and a Christie projector, so I was able to build just a few set pieces and
relied primarily on a series of very detailed projected computer graphic
images.

The few physical set pieces that did need to be built were
modeled using a combination of AutoCAD and Revit.

And some scenes required no physical set pieces at all.

I took a page from the scene changes in A Gentleman's
Guide by alternating scenes in front of mid-stage travelers, so that set
pieces could be positioned between scenes.

A Gentleman's
Guide to Love and Murder
(click to expand or collapse)
(June 2025)This Tony Award-winning musical comedy presented a very
unique challenge because of the 40 scene changes. And unlike most musicals,
there are no segues—one scene must seamlessly flow into the next.

Rather than reinvent the wheel, I mimicked the flexible
"picture box" design of the original Broadway production, building a
separate stage with its own proscenium, complete with a red draped curtain
that could quickly and silently open and close.

Scenes then alternated between those played in front of
the closed drapes of the picture box and those that utilized the
entire stage. My artist friend Tom Roberts even painted portraits of six
actors. At the appointed time, those portraits disappeared to allow the actual actors to make the portraits
come alive.

For all of the scenes played inside the picture box, I
created detailed rear-screen projections, many of which were animated.

The few physical set pieces—some of which consisted of
nothing more than two-dimensional cutouts—were designed using a combination
of AutoCAD and Revit.

Cabaret
(click to expand or collapse)
(September 2024)The set for
Cabaret featured a raised, multi-level platform and lots of art deco.

The major design element is the proscenium of the Kit Kat
Klub, the fictitious Berlin cabaret where Sally Bowles performs. The
orchestra is placed on a raised platform behind this.

The set was designed entirely using Revit, with some
elements, such as the art deco designs, created in AutoCAD. Stencils
and 3D art deco elements were then either printed onto adhesive-backed paper
used as stencils or laser-cut from thin wood and applied directly to the set.

She Loves Me

(click to expand or collapse)
(June 2023)The set for this fabulous musical posed the biggest
challenge to date, consisting of a jewel box that opens and closes
throughout the show. Building the complex geometry required extreme
precision.

When closed, you see the exterior of a perfume shop in
Budapest.

When open, the audience sees the two-story interior of
the shop.

Both Revit and AutoCAD were utilized, with the movable
wall framing entirely modeled in 3D.

Numerous other scenes utilize large wagons that are
stored in the wings, yet can be moved into place in less than a minute.

The show was a huge success, selling out nearly every
performance.

Into the Woods

(click to expand or collapse)
(June 2022)This complex production of Steven Sondheim's classic
Into the Woods incorporated 4 wagons, a raised platform, Rapunzel's
Tower, numerous trees, and lots of animated rear-screen projection.

Despite all of the organic shapes, the resulting set
looked very much like the Revit model.

Everything was modeled using Revit, including
other large movable pieces, including a large pumpkin coach.

The set, costumes, rear-screen projections, special
effects, and lighting combined to make this show a feast for the
eyes—truly a work of art.

Vino Veritas

(click to expand or collapse)
(March 2022)The set for this show was not complicated, but it had to
be convincing as the interior of the upscale home of a pair of
professional photographers. Knowing how important photography would be
to the design, I reached out to numerous photographers months before
starting set construction to get permission to reproduce their work. The
Revit model incorporated all of the photos, applied as decals.

Since most of the photos would be on the rear wall, I
used PhotoShop to create virtual matts and frames as part of each image
to save money on framing.

All of the advance planning resulted in ample time to
construct and dress the set, right down to the beautifully painted wood
floor.

Scarecrow for Hire

(click to expand or collapse)
(January 2022)
I had the unique opportunity to design the set for the
World-premiere of this film noire-style detective story with characters
based on The Wizard of Oz. The set was entirely virtual, using
rear-screen projection.

Animated backgrounds were produced by Steve Shain.
In a particularly effective scene, two of the
characters sit in an actual 1949 Chevy automobile while the animated
background makes it appear that they are driving through a bustling
downtown.

Lighting, costumes, and makeup were designed to make
the audience feel like they were watching an old black & white movie.

Proof
(click to expand or collapse)
(September 2021)
For Proof, I developed a detailed Revit model,
which allowed me to perfect the look I wanted...

...right down to the animated math formulas that were
projected onto the walls of the set before the opening of each act.

And Then There Were None

(click to expand or collapse)
(September 2019)Most Agatha Christie plays include a detailed plan, since
the location of doors and even the direction of swing can have an impact
on the subtle clues of her classic murder mysteries. My set design for
this show
included a lot of marble, all achieved with nothing more than paint and
a very talented set crew.

It also incorporated a rear-projected background with
an overcast sky transforming to a torrential storm with drenching rain
and flashes of lightning.

I also created a system to make it rain on stage, with water
pumped from a reservoir to a pipe suspended behind the French doors and
a rubber membrane to capture the water and direct it back to the
reservoir.
The combination of animated weather and real rain was
incredibly effective.

Sight lines were also very important. You don't want
any ticket holder to feel that they're missing a clue because they can't
see what's happening in a scene. Again, Revit enabled me to demonstrate
to the director that even the worst seats in the house had a full view
of all the action.
And just to make things even more interesting, the
final character to die gets hung on stage, so the set had to safely
carry her weight via a hidden steel cable so that when she falls, her
weight is carried by the cable and harness, rather than the noose around
her neck.

La Cage Aux Folles
(click to expand or collapse)
(September 2018)Musicals present many unique challenges, the biggest
being that scene changes often take place between or even during musical
numbers. For La Cage Aux Folles, there were 5 different set
configurations and a total of 15 scene changes.

To manage this, not only was the geometry all modeled
in Revit, I also used design options to represent the various scenes and
show them all on one sheet so that the production crew could better
understand how all of the platforms and set pieces would move.

Scapino
(click to expand or collapse)
(March 2018)For this zany farce, I designed a cartoon version of a
small Italian fishing village, with a dock, a boat, and several adjacent
buildings, none of whose walls were vertical. Since Revit at that time
did not support sloped walls, I first modeled the building masses using
FormIt.

With the director unsure of the viability of my
design, I turned to virtual reality and had her don a VR headset so
that she could inhabit the virtual model.
Every aspect of this set was modeled, right down to
the paint colors.

Noises Off
(click to expand or collapse)
(June 2017)With its 2-story set that must revolve 180-degrees,
Noises Off is always a challenge. The show's director added to this
challenge when she stated that it would be impossible to turn the entire
set and its staircases as a single unit.

Instead of starting out in Revit, I turned first to
AutoCAD to work out the set's intricate geometry as stacked 2D plan
views.
Once I was sure the geometry worked, I imported the
DWG file into Revit and modeled the walls and stairs in 3D. The
construction documents totaled 16 pages. It took 500 man-hours to build
and the completed set weighed approximately 2 tons, but took 5
stagehands less than 30 seconds to rotate.
The show was a huge success.

A Shayna Maidel
(click to expand or collapse)
(January 2017)The set for this Holocaust remembrance play featured a
raked (sloped) floor and walls that appear as if drawn as cutaway
isometric views, to reinforce the intrusion of dreams into reality.

The entire set was modeled in 3D using Revit,
both so that the director could confirm the viability of the design and
so that I could provide the set crew with a full set of dimensioned
drawings.

This was the first of my sets to include floors
painted to look like oak planks and a model that included all of the
furniture that would be seen on stage.

August: Osage County
(click to expand or collapse)
(April 2016)For this show, the entire set and all 198 seats in the
theater were modeled using Revit.

I could then place a camera in any set in the house to
convince the director that there were no sight-line issues.
The resulting set looked almost exactly like the Revit
model and I could quickly produce a complete set of construction
documents.

Moon Over Buffalo
(click to expand or collapse)
(September 2015)The set for this 5-door farce was designed entirely in 2D
in AutoCAD.

The simple design consisted of little more than doors,
walls, and a staircase.

Artwork for bricks seen beyond one doorway were based
on a material file provided with AutoCAD, which was printed using a
wide-format printer.

The Sound of Music
(click to expand or collapse)
(September 2014)The design of this set was done using both a scale model
and AutoCAD.

Each wagon was modeled individually in 3D and then
inserted into a 3D model of the stage.

Materials and textures were applied to surfaces of the
model and 3D rendered views produced for the director. The background
image was painted on canvas by a local artist.
