Sectional Views (剖视图)

In case of complex internal structures or complex structures behind the view, it might cause problems with too many hidden lines using standard or thographic view. For clarity and easy comprehension,sectional views are adopted.

为了清楚地表达机件内部或被遮盖部分的结构形状,以免画内部结构复杂的机件时,图形上出现过多的虚线,导致层次不清,影响图形清晰,给读图、画图带来困难,绘图时可采用“剖视图”画法。
