%X A series of practicable algorithms of preprocessing and information extracting from 2D engineering drawings was presented within 3D reconstruction based on B-rep method.These algorithms involved the whole course of preprocessing,including engineering drawings import,entity filter,views separation,coordinate standardization and views data process.By using these algorithms,it can not only obtain complete geometrical and topological information of the views,but also can deal withnon-orthographic views.It had been experimented in one CAD prototype system and shown to embody higher efficiency and practicability.
