Parametric Modeling is the formation of a digital model
constructed on a series of pre-programmed documentations or algorithms called
'parameters'. To be precise, the model, or elements are produced automatically
through internal logic arguments instead of by being manually operated.
Relationship of
Parametric Rules with Design Components:
Normally, parametric rules build relationships among various
design components. To take an instance, a rule might be created to ensure that
walls should begin at the floor level and reach underneath the ceiling.
If the floor-to-ceiling height is altered, the walls will automatically adjust
to the building suit. Some other instances include the height of the window sill
over the floor level, the connection between the walls and a slanting roof, the
association between the floor area & the window size, and so on. The same
algorithm can be used throughout a model so that if a specific component or
rule is altered, changes can be seen throughout the model. Consequently, the
model turns out to be a depiction of all the rules defined by the user.
Previous Cases of
Parametric Modeling:
Earlier, parametric modeling was used for special design
tasks.
·
Beijing National Stadium built for the 2008
Summer Olympics used professional Parametric Modeling software for making a
bowl geometry optimized for athletics, that would work well for football after
the Olympics.
·
The geometry of Shanghai Tower was also created
parametrically with the Grasshopper Modeling tool, facilitating the association
between form and wind loads.
·
Parametric Modeling also helped in performing structural
analysis, to process intricate geometric rules like determining the panel
layout of curvilinear methods and making rules for fabrication.
Parametric Modeling
with BIM into Mainstream Building Design:
Building Information Modeling (BIM) technology has
ushered Parametric Modeling into mainstream building design to a certain
extent. BIM is an extensive term that defines the procedure of producing and
handling digital information about a building or facility like bridges, tunnels,
highways, and so on. In general, BIM is based on the object definition with parametric
attributes like color. Hence, if a color scheme for a building gets altered,
every object with color attribute gets changed. Other parameters consist of
positional data, magnitudes, manufacturer's data, algorithms describing the form, and so on.

BIM is empowering the move from the design based on the
arduous and error-prone manual operation of the 'dumb' objects and includes
the competency of using 'smart' parametric logic. To get your building
