Using AutoCAD to draw plane figures

运用AutoCAD进行平面图形绘制时,首先,对平面图形进行分析和条件分析,对图形分析时,要确定哪些是已知圆弧,哪些是连接圆弧,哪些是已知线段,哪些是中间线段,哪些是连接线段,对尺寸标注时注意尺寸基准,定形尺寸和定位尺寸。其次,选择恰当的工具。最后,确定绘图顺序,完成图形的绘制及尺寸标注。

When using AutoCAD to draw plane graphics,firstly,analyze and analyze the plane graphics.When analyzing the graphics,determine which are known arcs,which are connected arcs,which are known segments,and which are intermediate.Line segments,which are connecting line segments,pay attention to size reference,shape size and positioning size when dimensioning.Second,choose the right tool.Finally,determine the drawing order,complete the drawing and dimensioning of the graphics.
