MODEL MILLING
    by Thomas Seebohm, with B.J. Novitski

	Rapid prototyping technologies such as 3D printers and
	stereolithography have achieved some popularity in
	producing architectural models. But these methods are
	limited in the size of the models they can produce, and
	they require expensive materials. So at School of
	Architecture at the University of Waterloo, we have
	been working with computer numerical control (CNC)
	milling to produce architectural models. We have
	demonstrated the utility of CNC machining by producing
	a 1:33 scale model of a curvilinear, precast-concrete
	structure for the Ballingdon Bridge in Suffolk County,
	England.

	Although most major structures are designed today with
	digital technologies, there are still times when a
	physical model is necessary. To understand a structure
	as complex and innovative as the Ballingdon Bridge, we
	wanted a physical model that we could hold in our
	hands.

	In investigating techniques for creating physical
	models from digital data, we found limitations with
	other rapid prototyping technologies. For example, the
	largest 3D printer from ZCorp produces models of a
	maximum size of  20 by 24 by 16 inches (500 by 600 by
	400 millimeters). While it is possible to produce
	larger models by assembling smaller pieces, this is
	cumbersome.

	Another concern is the expense of materials. Producing
	a 40-inch (101-centimeter) model of the bridge with a
	3D printer would have cost over $3000 (Canadian).

	To produce larger, less expensive models, we purchased
	a three-axis CNC router from Techno-Isel with a 50- by
	50-inch (127- by 127-centimeter) table and with a
	Z-axis travel of 6.5 inches (16.5 centimeters). The
	material cost of building the bridge model, using
	basswood, was less than $200.

	"Everything happens as if there were one-to-one
	oscillations between symmetry, order, rationality, and
	asymmetry, disorder, irrationality in the reactions
	between the epochs of civilizations. My own musical
	research on sounds with continuous variation in
	relation to time [...] led me to lean towards geometric
	structures based on straight lines: ruled surfaces"
	Iannis Xenakis, Greek composer and architect (1922 - 2001)

Michigan AIA Awards
    by ArchitectureWeek
    http://www.ArchitectureWeek.com/2006/0816/news_1-1.html

	In May 2006, in its annual awards program, the Michigan
	Chapter of the American Institute of Architects cited
	sixteen projects for design excellence and creativity.
	Many of these fall, coincidentally, into pairs of
	similar building types, inviting design comparisons.

Architecture Answer - for last week's quiz...
	During the early 1800s, Greek Revival was a prevalent
	style for residences in the United States. This style
	was spread by builder's common use of pattern books and
	by the influence of such architects as Town and Davis
	and designer/ writer Minard Lafever. Due in part to the
	publications of Andrew Jackson Downing in the
	mid-1840s, the Greek Revival style was challenged by a
	new style of architecture. What was this style? Can you
	name any of A.J. Downing's influential books?
