工程制图学习过程中常遇到的三种问题的分析及解决方法

Analysis of Three Common Problems in Learning Engineering Graphics and Corresponding Solving Methods

对在工程制图学习过程中常遇到的3种问题（因高中立体几何基础差,学不好或学不会画法几何,以及机械制图;课堂上一听就会,课后却不会做题;在机械制图部分的学习中忽视相关国家标准的规定）进行原因分析,提出相应的解决方法。

There are three common problems that often meet in learning Engineering Graphics.The reasons include three aspects.The firstly,the dimensional imagination ability is bad or weaker because they are not good at solid geometry in senior school.The secondly,they can understand in class while they cannot do well with homework after class.The thirdly,they often neglect the rules concerning with national standard in the study of the mechanical graphics.The corresponding methods are proposed.
