摘要
Section cutting is used in geological work normally. In recent years,the domestic experts and scholars concentrated on the development and study of automatic section cutting and ignored the study of section cutting on paper map,computer grating graph and vector bottom image with no height properties. In today and some time in future when the computer drawing technology developing fast,especially the unprofessional geologist,can’t finish section cutting without traditional customs. Based on traditional ideas,the application of AutoCAD in secondary geological section cutting development is discussed.
