在工厂设计的钢结构设计中，经常使用构件的图形轮廓，由于构件的图形构成形式多样，可能存在许多弧线和悬边，并且可能不封闭，需要一个有效的算法来求取这种带悬边的轮廓.文中提出了悬树和扩展轮廓的概念，通过对扩展轮廓的分析和定义，使用动态坐标系和动态包围盒技术，设计了一个扩展轮廓的求取算法.最后论述了与扩展轮廓相关的一些操作特性.

Component contour is often used in constructing steel structureof plant design. There are many kinds of lines in the component layout such as arc line and suspended edges which are not closed to form a loop. So, an algorithm to extract the contour with suspended edges is needed. Basic concepts and definition of suspended tree and extended contour are given, an algorithm to extract it is presented using techniques of dynamic local coordinate system and adaptive bounding box. At last, some operations related to extended contour are described.
