PARAMETRIC TRANSFORMATION
PARAMETRIC TRANSFORMATION
Compared to the 2D and 3D modifications to
both chair projects, the One to Several Table
parametric app offers a much higher degree of
customization. The app allows you to produce a
file with dimensions that precisly match your
program and to adjust every part to fit your
exact material thickness (TMAX). The app has
optional features, enabling you to set hole
diameter to match fasteners and to adjust snig-
lets to match any alternative tool diameters.
PARAMETRIC DESIGN
The One to Several Table’s parametric opera-
tions were designed to offer tangible, functional
differences from one version to the next. To
understand the One to Several Table’s
parametric design, it helps to examine it
through the lens of parametric equations. We
can break down the table as a collection of con-
stants and variables interrelated by functions.
As you adjust its length or width, the table’s
four legs, feet, and joinery maintain a constant
relationship to the top. Only the distances
between the joints and assemblies change. A
more complex operation, defined by an if/then
statement, adds or substracts bays to the
table’s torsion frame. If the table width increa-
ses beyond a certain dimension, then the app
adds an additional cross member to provide
extra structural support. While the number of
cross members may change, all of the joinery
details are constant. And though the distance
between cross members increases or decrea-
ses, they are always spaced equally.
