| Abstract |
Recently, the needs for sharing and exchanging drawing information between 2D and 3D CAD data in complex engineering fields are well recognized throughout the construction industries. The purpose of this study is to develop product model-based information framework for exchange and sharing of CAD drawing information between 2D and 3D CAD data in complex engineering fields. The current IFC2x2 model has the model space elements definitions to represent 2D drawing but not the paper space elements definitions. Therefore, it is necessary to extend the current IFC model to include the paper space elements for complex products. The study has been developed 1) IFC paper space extension model, 2) information framework to enable sharing and exchange of product model by adding various information factors, 3) the standard APIs and an IFC2DBrowser. |
