摘要 为了解决传统CAD/CAE集成系统对同一产品串行生成不同的全细节层次模型和抽象模型的低效性与不实用性,采用基于特征的多分辨率建模技术和LOD技术,通过建立和查询存储在公共特征库中的多分辨率特征及LOD/LOA模型链表,实现自定义层次模型的并行快速同步提取和修改。实际应用表明,该方法能快速求得基于不同细节层次和抽象层次的简化模型,提高了实体模型设计与分析的效率。 Traditional CAD/CAE integrated system work in a serial way,it generates two different models from one product.But simplified models at various levels of detail(LODs) and levels of abstraction(LOAs) are frequently more desirable than the full details of the models.This paper took feature-based multi-resolution modeling and LOD techniques,concurrently created and manipulated multi-resolution model table and LOD/LOA lists,extracted the custom size model information from the feature store through a selection pr...
