| 摘 要： | 对基于关联图形的三视图联动作了初步的研究。在单视图联动的基础上，提出了实现三视图联动的基本思想，包括以下几个方面的内容：扩展关联图形子图形表，建立不同视图子图形间的投影关系，分别建立3个视图的基本子图形的约束关系树，并对某些特殊的工程约束进行预处理。在此基础上，实现三视图的一致联动。 |

| Abstract: | An approach for three viewpoints engineering drawing co-variation based on relating-graph is described in the paper. Based on co-variation method for one viewpoint engineering drawing, the co-variational idea for three viewpoints engineering drawing is proposed, which include extending relating-graph table, building the constraint tree for every viewpoint engineering drawing and pre-processing several special engineering constraints. With this method, the co-variation for three viewpoints engineering drawing can be realized. |
| Keywords: | relating-graph three viewpoints engineering drawing co-variation parametric design |
