切割体的识读方法

The Reading of Cutting Body

切割体识读一直是《化工制图》的教学难点,对学生的空间想象力要求较高,在作图过程中经常出现"多线"、"漏线"的情况。针对这些问题,本文阐述了切割体识读的基础和原理,并以举例的形式说明如何利用"一分、二想、三综合"的方法对切割体进行读图和作图。

The reading of cutting body has always been a difficult point in the teaching of chemical cartography,which need high requirements for students’ spatial imagination. In the process of drawing, " multiple lines" and " missing lines" often occur. In view of these problems,this paper expounds the basis and principle of reading the cutting body,and illustrates how to use the method of "one point,two thoughts,three synthesis" to read and draw the cutting body.
