nD-CAD를 위한 사용자 정의 속성 BIM 소프트웨어 호환성에 대한 연구

Building Information Modeling (BIM) technologies have increasingly utilized in the construction industries. Interoperability is important capability for BIM software data to run computer application throughout life cycle of project. The nD-CAD include graphics data and non-graphics data. These are the important elements in the project integrate management and interoperability. Thus, this study covers tests of the interoperability for these data among commercial nD-CAD softwares and provide direction to improve it. As result, non-graphics data show the lack of interoperability than graphics data. Futhermore, there should be a shift of emphasis from the graphic data to the non-graphics data in a BIM research field.
