허용 가능한 LOD의 상하한을 고려한 특징형상 3D CAD 조립체모델의 단순화

Abstract

Three-dimensional (3D) computer-aided design (CAD) models require different levels of detail (LODs)depending on their purpose. Therefore, it is beneficial to automatically simplify 3D CAD assembly models tomeet the desired LOD. Feature-based 3D CAD assembly models typically have the lowest and highest feasiblelimits of LOD during simplification. In order to help users obtain a feasible simplification result, we propose amethod to simplify feature-based 3D CAD assembly models by determining the lowest and highest limits ofLOD. The proposed method is verified through experiments using a simplification prototype implemented as aplug-in type module on Siemens NX.
