Abstract

It is necessary to construct an equipment catalog in plant design. A different level of detail may be needed for the three-dimensional (3D) computer aided design (CAD) data for equipment, depending on the purpose. Equipment suppliers provide CAD data with high complexity, whereas plant designers need CAD data with low complexity. Therefore, it is necessary to simplify the 3D CAD assembly data. To resolve this issue, a system for automatically simplifying the 3D CAD assembly data of equipment was developed. This paper presents the architecture of the system, the detailed functions of the system, and a neutral data format used for uploading simplified 3D CAD assembly data to a plant 3D CAD system. In addition, experiment results using the prototype system are explained.

플랜트 설계를 위해서는 기자재 카탈로그를 구축해야 한다. 기자재의 3 차원 CAD 모델은 목적에 따라 서로 다른 상세도를 가진다. 기자재 제작사는 높은 상세도를 갖는 CAD 데이터를 제공하는 반면에 플랜트 엔지니어링사는 낮은 상세도를 가지는 CAD 데이터가 필요하다. 이와 같은 문제를 해결하기 위해서 기자재 3D CAD 조립체 데이터를 자동으로 간략화하는 시스템을 개발하였다. 이 논문에서는 간략화 시스템의 구조, 상세 기능과 함께 카탈로그 생성을 위한 중립 데이터 형식을 제안한다. 그리고 프로토타입 시스템을 이용한 간략화 실험 결과를 설명한다.
