基于AutoCAD环境下的一种二维平面图消隐方法

Method of eliminating for planar draft based on environment of AutoCAD

为解决二维平面图形的消隐问题，针对二维平面图的自动绘制，提出了一种非人机交互，自动寻找内外边界，进而与内外边界求交点，最终实现装配图中隐藏线的自动消去的方法．在实际应用中效果良好．

For resolving the problem of eliminating for the planar draft, aiming at the automatic drawing of planar draft, the paper presents a method that needs no man-machine conversation and automatically searches for the inner-and outer-borders, then converts the entity to be eliminated to data-list and makes out their cross points with the borders, finally eliminated the hidden-lines in the assemble drawing.
