CAD and Drafting
The Computer Graphics Technology Department at Purdue University
is divided into four areas of expertise: Interactive Multimedia, Manufacturing Graphics,
Technical Animation, and Construction Graphics Communication. Each
student must declare an area of concentration, and this last area—Construction Graphics—was
mine. While I haven’t had much chance to use it professionally, the CGC area was the basis
for much of my advanced college coursework
My
final CGC project at Purdue University was to create a complete document set of a floor plan.
This plan, called “Montgomery,” consists of a complete architectural document set: foundation,
floor, and roof plans; full and partial elevations; and of course, the final rendering. This
document was creating in Revit 3.1, an architectural
program so good that AutoDesk—the makers of AutoCAD—just couldn’t stand it
any more: they bought them out.
On a more personal note, this rendering of Montgomery is designed as if it were located in my home
town of Pequannock, New Jersey, and faces south for maximum sunlight exposure in the front
rooms. As for the sun itself, it is positioned
exactly where it would have been on the day, hour, and minute of my birth. (HTML)
One of the most complex jobs of the Construction Graphics Technologist is to create an appropriate
rendering of a pre-existing blueprint. If nothing else, keeping track of thirty-some-odd
size E (34"×44") pages in a standard cubicle presents its own
significant challenges! But all joking aside, the amount of detail on a good blueprint
is well beyond that with which the CAD operator is often presented. Whereas a single-page
floor plan requires the operator to make some minor allowances, a complete document
set leaves no margin for error.
Please note that the third page—an interior
view of the first floor—is incomplete. I hope to replace this with a completed page as soon
as I again have access to Revit. (804KB PDF)
Drafting isn’t just about creating
3-D renderings; the builders need details, too. This project was to create
a detailed view of the inside of the walls and flooring in a six-story building, with three
levels of detail: an overall view of all six floors, a close-up of a
single floor, and an even closer detail of the point where the floor meets the wall. I have
also included the original information we received, for comparison sake. (628KB PDF)
My first position after graduating from
Purdue was as a CAD engineer for S&S
Fire Apparatus Co.. While this position did involve some design work, the primary focus was the
utilization of AutoCAD’s Libraries function to create 2D depictions of requested apparatus,
per the customer’s specifications. With thousands of options grouped into dozens of categories,
this is no simple task. The final drawing shows exactly what the customer expects—not only
as a means of helping said customer visualize his apparatus, but more importantly, to help
the craftspeople on the factory floor visualize it. (124KB PDF)
An early
project in my time at Purdue was to create a vector-based (i.e. scaleable) architectural
rendering. Having taught myself enough DenebaCAD to use it to design my wife’s and my dream
house, I decided to colorize a shot of the breakfast nook in the morning. In the end,
it reminded me of the sunrises my wife and I often watch over the Atlantic Ocean while vacationing
at my grandparents’ beach house. From thence came the title Sunrise on the Beach.
