Parametric Modeling Methodology for Roof Components of the Traditional Korean House with Focus on Chu-nyeo , Gal-mo-san-bang , and Seon-ja-yeon

The roof of the traditional Korean house, Han-ok, has a curvilinear shape and its design derives from accumulated design principles. Three-dimensional (3-D) object-oriented parametric modeling technology enables the modeling of irregular and atypical geometries by embedding numerically analyzed information. In this study, the authors devised a methodology of parametric modeling for the roof components of a traditional Korean house, such as Chu-nyeo, Gal-mo-san-bang, and Seon-ja-yeon, which have the most complex shapes and 3-D curves. While respecting the conventional drawing method used by craftsmen, the authors re-defined primary factors and systematized the parametric logic considering not only modeling efficiency and accuracy but also user interface and convenience.
