1982; Sacks, Eastman, & Lee, 2004). Solid modeling is the most enhanced geometric
modeling method which provides accurate representation of a 3D shape, by
derivation of any shape measurements, by cutting of sections and by automatic
dimensioning features (Sacks, Eastman, & Lee, 2004). Even now, most of the CAAD
systems developed for Architecture, Engineering and Construction (AEC) industry
make use of solid modeling method (Eastman, 1999), like one of the major CAAD
software package, AutoCAD.
Although ‘geometric modeling’ opens up new alternatives and ways of working in
architectural design, there are also several problems in using this method. The main
problem is the spatial coordinate system which every geometrically defined object
based on (Saitz, 2005). For instance, if there appears a change in the design, the user
has to revise major sections of the drawing or draw the entire drawing from scratch.
This process of revising a solid model is a tedious process and also, defining a 3D
solid shape requires more effort than defining its equivalent 2D representations
(Sacks, Eastman, & Lee, 2004). These given drawbacks about ‘geometric modeling’
lead to a new modeling method, ‘parametric modeling’ to emerge.
‘Parametric modeling’ is simply rooted in ‘geometric modeling’ with extending its
ease of use and usually utilized in mechanical engineering and building design. “A
parametric model is defined by the rules and constraints, which define different
aspects of the building and their relationship to each other” (Katz, 2007). Therefore,
the geometry identified in the ‘parametric modeling’ has strong links with its
dimensions and parameters (Saitz, 2005). For this reason, when the parametric value
of an object changes, its geometry automatically updates. The most important feature
