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个视图的基于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。
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.
