I've heard it said that people think computer drawings are final and locked in. Actually, the truth is that pencil draftings, marker renderings, and cardboard models are locked in. It is much easier to edit a computer drawing, model, or rendering or generate any number of alternative ideas.
Most Art Departments have gone digital for graphics, budgeting, Internet. Leaving out CAD is like driving a 2001 car with a 1980 engine. Digitizing the drawings will bring the full power of the computer into play.
A recent project, I used the computer exclusively: design, computer models, computer renderings, working drawings, even walk-throughs. I saved many hours of work.
Another project was done entirely by hand. I drew some sets over and over on different sheets, different scales, with many changes. I could have done this in half the time had it been entirely on the computer.
The project before, the Art Director surveyed the locations and drafted them by hand. Then had me redraw them on the computer, using his hand draftings as my data. Not only did this involve drawing each of the locations twice, but lost the accuracy of the computer by using less accurate hand draftings as data - "GIGO" (garbage in - garbage out). Had I done the survey and drawn each location once on the computer, It would have saved time and been more accurate.
I recently interviewed for a job to make a computer model. Drawings and a cardboard model were already started. I asked what they wanted from the computer model that they couldn't get from the cardboard model and the Art Director wasn't sure. Had I done the drawings on the computer and extrapolated these into a computer model, significant time savings would have resulted. As it was, I would have simply been duplicating work already done and saved little.
Imagine this example formula:
Draw once by hand (10 hours) + redraw/trace with changes (8 hours) + redraw/trace with changes (8 hours) = 26 hours.
Draw once by hand (10 hours) + redraw on the computer (12 hours) + make changes (1 hour) + make changes (1 hour) = 24 hours; save little.
Draw once on the computer (12 hours) + make changes (1 hour) + make changes (1 hour) = 14 hours; save almost half.

The same plan and elevations can then be used to make a rendering. This rendering was made in AutoCAD © R12. Materials were created in Photoshop 5.

I find CAD to be an excellent tool for laying out parts for Art Department study models.
Since the notes and dimensions are on separate layers, by turning off these layers, the
layouts for the model are free of these unwanted annotations. The layouts are very
accurate and since they are generated from the same data, match the construction drawings
exactly. AutoCAD © R12.
There are many advantages to using the computer in Visual Effects to preprogram the motion control, build the right amount of a model, to give a head start to CGI models. We used this method on Batman and Robin and Shrek.
Changes are fast and easy. Simple changes are quick, big changes are
Changes are faster.

Changes are a snap
much faster. Try making a room in the middle of the house 2 feet longer
using an electrical eraser and pencil. With my computer, I can usually
make such a change in about 15 seconds. You suddenly decide to flop
the entire set. Even erasing the notes and dimensions, turning the vellum
over, and relettering would take a few minutes, I can do it in about five
seconds. Rotating a set 5 degrees would take the computer a few seconds
as opposed to erasing and redrawing with pencil. Even if you were to
cut and tape a drawing in a new configuration, it will take longer than with the
computer and would not look as neat.

The cyan shaded area is where I stretched the center of this house 5 feet in less than one minute.

Flopping this house, including the lettering, took about 5 seconds.

Computer models are more versatile.
In additions to the fast changes listed above, there are other advantages
to computer modeling and rendering. Materials and colors can be
changed quickly. I've produced dozens of renderings for some projects
exploring different colors, materials, and lighting schemes. Viewing angles
and composition can be changed and rerendered in minutes, not hours.
Try doing a walk-through animation with marker renderings. As a model
maker for over eighteen years, I can assure you that a computer model
makes much less mess, dust, and toxic fumes

Two weeks of drawing were in your car when it was stolen, plot another copy.
I can store the drawings from an entire show on a CD-ROM or a Zip disk.
I can't think of a reason I've heard that I can't refute.
A Production Designer told me that "Carpenters don't like CAD drawings." I was a Prop Builder for 18 years. We loved CAD drawings. They are clean, clear, legible, the dimensions add up, and usually we stood around waiting for them less. Of course an inexperienced CAD operator can make bad drawings, just as an inexperienced pencil draftsperson can make bad drawings.
"CAD drawings are too clean." If you like inconsistent line weights, smudges, and lines that extend at the corners, this can be done in CAD. I don’t do these because I like clean accurate drawings.
"CAD drawings take longer than pencil." This is true for some individual drawings, but as a package, on most projects, 100% use of CAD would be considerably faster. An inexperienced CAD operator might take longer, just as an inexperienced pencil draftsman can take longer. But then with pencil, I can work more hours and make more money.
Please e-mail me some more objections, I’ll add my rebuttal here.
Note: These drawings are presented here for portfolio purposes only. These drawings are not available for sale or to be given away in hard copy or digitally in any scale. I will be happy to show hard-copy during a legitimate job interview for Set Designer.
Cleaner.
Have you ever seen a drawing that has been reworked and changed for months?
It's gray with graphite. You can see where recent changes were made, they are the clean areas. A CAD drawing never gets dirty.

Above is a computer drawing, below is a pencil drawing.

Backups and archiving.
Have you ever had a blue-print machine eat your vellum. You have no choice but
to sit down and redraw it. I simply plot another copy in ten minutes. Of course, I do
regular back-ups of my computer files and store them off-site.
Sorry, I can't do much about the car.
This is in addition to the plots which are stored like any other vellum.
Digital data can be transmitted electronically or faxed.
Have you ever tried to fax or e-mail an E size sheet of vellum? I have printers in a variety of sizes, including 8 1/2 x 11.
I can also fax directly from the computer. The newest AutoCAD was designed to interact with the web.
