| Abstract: |
| 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. |
| Key words: Feature location, search strategy, heuristic search, algorithm, piping, CAD. |
