Search Strategy Study of Piping Features Location Based on Smartline Model
基于智能线模型的管线特征定位搜索策略研究

The problem of features location and label occurs frequently in the production of many types of engineering CAD. For the efficiency of features location in piping CAD system, this paper presents strategies according to the characteristics of pipe-lines in plan & section drawing. Some methods of heuristic search based on smart-line model are introduced which make it possible to accomplish automatic placement of pipe-line features in local search space.
