画法几何与工程制图

时间:2020-03-11 15:20

      全书要紧情节有:阴影法,几何几何图形的正阴影,正阴影转换法,定位情况,量情况,曲面张,轴侧阴影,数目字电子电脑在图解中的使用。

      堵盖连着封圈是得以取下的,取下后有三个恒定螺钉,用于恒定过滤结合筒。

      本科目为后续专业课中的图片示意法子打下地基。

      这种阴影使用在轴侧阴影相安无事光打样的阴影图中。

      他不得不做实际职业,随时盯梢测和绘图打交道。

      2在维持原本画法几何学问思想体系静止,维持原教材字风骨特征的地基上,对教材情节进展了以次几点审订:1、三章增多了例题。

      比值的老幼,是指其比值的老幼。

      3)斜轴测图正斜轴测图、水面斜轴测图。

      难题:螺旋面的画法。
