尺寸标注的动态编辑与自适应处理算法

The Algorithm of Dynamic Arrange and Self adaptive Processing for Dimension

针对目前交互或参数化设计中尺寸标注存在的不足，通过对视图标注域的分区、关联尺寸的提取及自动分层，实现了删除、插入及参数修改而引起尺寸包容性变化等问题的自适应处理．

To solve the deficiency of dimension in the interactive processing or the parameter design at present, the authors present a method for deleting, inserting and modifying dimensions in engineering drawings. The relations between dimensions are extracted, the view areas and different level dimensions are divided, and self adaptive processings of the dimension changes are implemented.
