Columns can be either
compounded of parts or made as a single
piece. Columns are frequently used to
support beams or arches on which the
upper parts of walls or ceilings rest.
The term column in architecture refers
specifically to such a structural element
that also has certain proportional and
decorative features. A column might
not support any major structure but
be a decorative or triumphant feature
with, for example, a statue on top.
Entasis is the application
of a convex curve to a surface for aesthetic
purposes. Its best-known use is in certain
orders of Classical columns that bulge
slightly in the middle.
Single-piece columns are among the heaviest
stones used in architecture. Other stone
columns are created out of multiple
sections of stone, mortared or dry-fit
together. In many classical sites, sectioned
columns were carved with a center hole
or depression so that they could be
pegged together, using stone or metal
pins. The design of most classical columns
incorporates entasis
(the inclusion of a slight outward curve
in the sides) plus a reduction in diameter
along the height of the column, so that
the top is as little as 83% of the bottom
diameter. This reduction mimics the
parallax effects which the eye expects
to see, and tends to make columns look
taller and straighter than they are
while entasis adds
to that effect.
The wind is inevitable
to a ship as the ship will sail because
of the wind. It contains the meaning
that smooth sailing before the wind
implies the design specification estimated
and validated in Ventus
connects to the downstream tool, Navis
smoothly. Thus, Entasys Design concentrates
on the research and development of innovative
design automation technology with "Entasis
Sprit". Entasis
is a metaphorical example of the designer's
effort to achieve the perfect design.
