Abstract
There have been several efforts for the investigation of the formal development team which was formed in the IAI to develop a common 2D standard specification between ISO/STEP and IAI/IFC since 2002. As a result, a drafting model has been included in the IFC2.x2 model. However, to be used actively in the construction practice for construction drawing exchange, the IFC model should be extended to the paper space for multiple views, drawing output, and delivery of drawings. Therefore, in this paper, the methodology of relating STEP and IFC has been investigated and schema extension of paper space(drawing sheet, presentation view, view pipeline), complex entity(leader), and dimension(associative) have been achieved. The resulting, IFC model will enable a basic harmonization with KOSDIC. SCADEC, and STEP-CDS by retaining the current IFC architecture. In addition, IT systems for the construction industry can be beneficial from the developed data model.
